Three little-known ways to significantly save fuel in traffic jams. How to save on gasoline (no nonsense about magnets and additives).


What is the trade-off between the need for speed and common sense?

It is very important to remember that not every travel speed saves fuel. Experts recommend moving the car at a speed not exceeding 2/3 of the maximum possible. Acceleration in high gear with a further transition to coasting is economical outside the city on a good track.
In the city, where there are constant traffic jams and idle times at traffic lights, it is useless. In addition, constant acceleration / deceleration will lead to high costs.
Smooth engine starting and gradual acceleration reduce the need for braking. Every time the brake pedal is depressed, the rolling inertia of the machine becomes useless and harmful to the brake pads.
Just like in any other business, moderation is important here. Very slow city traffic will interfere with traffic and, of course, annoy other motorists.
The automotive market gave a worthy assessment to the new product – a stylish and very powerful car Renault Laguna. Motorists immediately noticed the sporty appearance of the Renault Laguna Roadster. Connoisseurs instantly noted its excellent aerodynamics.

At what speed can you save?

In light of the ever-increasing price of fuel, the desire to save it is of great importance. Much affects its consumption, and speed in this case does not take the last place. That is why car owners are often interested in what speed will save fuel?

Economical driving

It is difficult to give an unambiguous answer to this question, since the cars are different in design. They have different aerodynamics, power units and gearboxes. Therefore, the speed at which you can save is different.
It is known that the faster a car accelerates, the more fuel it needs. Its consumption increases with increasing crankshaft speed. So, savings are achieved only at low speeds.
When starting off, you do not need to put pressure on the gas, the car should accelerate and pick up speed smoothly. Having reached the desired speed, it should be kept constant. The revolutions of the crankshaft of a gasoline engine should not exceed 2000-2500 rpm. Fuel consumption in a particular case will be minimal. As for the diesel engine, here the limits are lower – 1500-2000 rpm.
If we say something about the economical speed, then it is achieved when the crankshaft rotates 2000-3000 rpm. For modern vehicles, the value varies between 90-110 km / h

With an increase in dynamics, fuel consumption increases for the following 2 reasons:
1 rpm increases;
2, the resistance of the oncoming air flow increases.
Since old cars have poor aerodynamics, the economical speed for them is 80-90 km / h. If the car has a four-speed gearbox, then its most optimal speed for saving is 75 km / h.

How else can you save fuel?

Economical driving requires compliance with certain rules. Savings can be achieved calmly without sudden acceleration and deceleration. On a suburban road, of course, this can be achieved, but in the city, due to a series of constant start-off stops, this will not work.
Drivers should remember: too much fuel and time in the city “take” traffic jams.
Even, seemingly, the shortest path, clogged with cars and with many traffic lights, “eats” more fuel than a long, but free and straight road.
There are many opportunities to save “fuel” in the gas tank.
You can save, for example, gasoline by keeping on the track for other vehicles at a distance of 20-25 m. The point is that the rarefaction zone emanating from the vehicle in front reduces the resistance of the oncoming air flow. This is clearly noticeable on vehicles with poor aerodynamics. Since the topic of aerodynamic drag was touched upon, it must be remembered that motorists themselves often become the culprits of its deterioration, laying bulky cargo on the roofs of their cars. Any trunk with a streamlined shape increases the engine “zhor” by 20%. The heavier the load placed on the roof of the car, the greater the gas mileage will be.
Another possibility to reduce aerodynamics is to open car windows in the direction of travel.
Much also depends on the quality of the fuel. Poor quality fuel increases consumption. Some car owners, wanting to save money, fill their “iron horses” with fuel with a low octane number. They replace the AI-95 with the AI-92. In reality, such a replacement does not bring benefits. The engine will use up such fuel faster, and modern engines with a high compression ratio require high octane fuel. Otherwise, knocking may occur and the engine may be damaged.
Consequently, the cost of repairing and replacing the motor will reduce such savings to zero. Do not forget about the technical condition of vehicles. A serviceable car “eats” much less gasoline.

Influence of speed on flow

How closely related parameters such as speed and “gluttony” are, experts have studied in detail for a long time. The Swiss magazine Automobile Revue published the results of the work carried out from 1987 to 1996. These were test data from various cars that moved at a speed of 60 to 180 km / h.

It became obvious that when representatives of various car brands are accelerated from 100 to 180 km / h, the fuel consumption coefficient can vary within the range of 1.86-4.49. This parameter depends on different types of resistance, engine torque, rolling resistance and is expressed in kW.

For example, when driving at a speed of 100 km / h, it is equal to 14 kW, and at 200 km / h, this coefficient rises to 80 kW. Thus, in the second case, the fuel consumption rises to 15 liters per 100 km.

Driving style

From the very beginning, every driver forms the optimal driving style for himself. At the same time, at first, it rarely does without increased fuel consumption due to a sharp press on the accelerator pedal, braking. After bringing the basic skills to automatism, the manner of operating the machine often changes.

On the other hand, there is a group of drivers who advocate “aggressive” driving style. They sharply accelerate cars, slow down, move at high speeds on uneven roads. Such actions lead to increased combustion of gasoline, diesel fuel.

For greater savings, it is recommended to drive smoothly without sudden movements, even driving on the track. In addition, it is important to change gears on time, avoiding unnecessary torque increases during engine operation.

Three little-known ways to significantly save fuel in traffic jams. How to save on gasoline (no nonsense about magnets and additives).

Many young drivers cannot imagine their car without a powerful audio system. They install additional speakers, amplifiers to use the full power while driving. It should be borne in mind that the more electrical appliances operate while driving on the road, the more gasoline will be consumed.

How to save

Well-formed driving skills will help to reduce fuel consumption. Among them, one can single out the correct gear shifting on a car with “mechanics”. It is important to accelerate the vehicle at the rpm corresponding to the engine torque. In this case, press the accelerator pedal smoothly, avoiding sudden movements.

On the highway, it is better to stick to a cruising speed of 90 km / h. This tactic has shown its expediency, since against the background of tangible savings, the time to overcome a long distance remains at a decent level.

If, while driving, there is a need for long stops, it is better to turn off the engine at this time. At the same time, it is advisable to avoid traffic jams and not move during rush hours. To save money, it is recommended to give priority to an even ride without harsh braking and acceleration.

Tire pressure also affects fuel consumption, so this parameter must be constantly monitored. Insufficiently inflated tires contribute to unnecessary gasoline costs.

How speed and fuel consumption are related

In order to correctly track the relationship between speed indicators and fuel consumption, it is worth familiarizing yourself with a study that was carried out for 9 years, from 1987 to 1996. Its outcome was published in the renowned Automobile Revue. The testing involved cars of various brands, the speed range of which varied from 60 to 180 km / h.

The outcome of the research showed that accelerating from 100-180 km / h, the fuel consumption coefficient will be in the range of 1.86-4.49, which directly depends on the characteristics of resistance, the force of rotation of the crankshaft. The unit is kW.

For example, if the car is moving at a speed of 100 km / h, then the coefficient will be 14 kW, and when accelerating to 200 km / h, it will increase 6 times. Based on this, gasoline consumption increases to 15 l / 100 km.

What speed to choose to save fuel

In cars with an automatic transmission, all the work is done by a computer, but the mechanics will have to tinker with.

Based on theoretical data:

  1. Fuel consumption is less if the driver rarely accelerates to high speeds and changes gears on time.
  2. Pressing the gas, you should do it with special smoothness in order to prevent the enrichment of the mixture during acceleration.

In the city

Gasoline costs in the same city can vary dramatically depending on driving style:

  1. One of the main points is the correct choice of the trajectory of movement. It is better to choose a longer path, but without traffic jams and numerous traffic lights. This is especially true in megacities.
  2. The most rational approach is smooth acceleration and timely transition to the desired gear. While driving on level ground, 5th gear can be used, however, at low rpm, fuel consumption will increase more than at a similar speed using 4th gear.
  3. If, nevertheless, traffic jams could not be avoided or the traffic light is too long, then feel free to turn off the engine during downtime.
  4. To save money correctly, give preference to a uniform ride, and before the next stop, do not accelerate, switch to coasting or engine braking.

On the highway

When driving on the Autobahn, many of the criteria for economy will be similar to driving in the city:

  1. The first is that frequent and abrupt changes in speed will increase fuel costs several times, so drive at the speed of traffic.
  2. Second, don’t go full speed. Moderate driving speed is the key to effectively reducing gas mileage. The optimal speed is 80-100 km / h.
  3. Third, do not press on the brake suddenly. Keep a safe distance from the vehicle ahead.
  4. Fourth, as soon as you realize that there is a turn ahead of you, slowly release the gas, especially if the weather is bad.
  5. Fifth, in the event of a vehicle malfunction, fuel costs can skyrocket. Do not neglect the technical inspections, and also during the time give the car for repair if the slightest malfunction appears.

Summing up, we can conclude that the optimal speed is not higher than 90-100 km / h. By developing the right driving habits and skills, you can save a lot on fuel.

No gas attacks

Many factors affect fuel consumption. First of all, this is aerodynamics, power and thrust of the engine at low revs, as well as resistance of the road surface. A lot of energy is spent on acceleration to cruising speeds, but then the force is spent exclusively on overcoming the resistance of the environment. Therefore, to reduce emissions of harmful substances from the exhaust pipe, environmentalists recommend resorting to a simple mechanism for handling the gas pedal. You can press on it only at the start, but after a speed of 30 km / h, light touches are enough. Then the engine will not spin over 2500 rpm. And this is quite enough for life in the city.

Modern motors have good low-end performance. Thanks to direct injection, it is possible to achieve 80% of the torque at 1200 rpm. If the engine is also equipped with a variable valve timing system, then 80% of the thrust is available from 1000 rpm. This means that you do not need to accelerate for a smooth start and acceleration. By the way, according to the standards of the average European cycle, acceleration to “hundreds” is carried out in 30 seconds, and such dynamics just happens within the 2000 rpm range.

Keeping the engine running at excess speed is tricky. If the car is equipped with a manual manual transmission, then you can smoothly release the pedal already at idle, and the engine equipped with electronic injection will raise the traction a little by itself so as not to stall. The new BMW and MINI models already have a driverless start system. In order to avoid unnecessary overgassing, the electronics itself sets the correct level of fuel supply.

The higher the better

But then it is necessary to reach the highest gear as soon as possible. At a speed of 30 km / h, the fourth stage must be switched on, and at 60 km / h, the “sixth” must be set. Then the engine will rotate below 2000 rpm, the fuel consumption will drop significantly. For example, at 3000 rpm, 3.5 times more fuel is consumed than at 1500 rpm.

Thus, driving at a speed of 50-60 km / h in top gear will reduce the consumption of a 1.6-liter engine to 4-5 liters per “hundred”. This technique is useful when the fuel level is zero, when you need to reach the nearest gas station with the last of your strength.

In addition, modern cars use the “Start-Stop” system, which automatically turns off the engine at forced stops. On “old ladies” you can turn off the engine yourself. Standing in traffic jams and in front of traffic lights without a working power unit adds up to another 5% fuel economy. But here we must remember that frequent starts harm the mechanics, and it is better to turn off the engine at stops lasting more than one minute.

Tires and aerodynamics

Well-inflated tires help save fuel. Under standard conditions, many manufacturers recommend inflating the “front” to 2.2 bar, and the rear wheels to 2.3 bar. This is the most comfortable pressure for R16 and R17 wheels. But many do not watch the tires for months, allow the pressure to bleed off and forget that on a loaded car the tire sags, increasing the contact patch, which leads to increased wear and increased fuel consumption. Therefore, to travel with your family to the country with simple belongings in the trunk, you need to increase the tire pressure. A different value is set for each car model and wheel size. For example, on a Focus II with 205/55 R 17 wheels, it is recommended to run 2.8 bar in the rear tires. And for Ford Mondeo, the rear wheels 215/50 R 17 are recommended to be pumped up to 2.9 bar. Then the contact patch of the wheels with the asphalt straightens to standard values ​​and decreases by about 1.5 times compared to the minimum pressure threshold. As a result, rolling resistance on asphalt will decrease. And this is about 10% fuel savings. But before pumping up the wheels, you need to look at the instructions.

“The pressure recommended for a particular car can be found on special stickers, which are usually located on the fuel filler flap, in the doorway or on the glove compartment,” says Alexey Zayakin, head of the brand promotion and internal communications group at Nokian Tires LLC. “Following the manufacturer’s recommendations will have a positive effect on tire performance: grip, aquaplaning resistance, fuel efficiency and tire mileage.”

But the most important thing is that in order to avoid an increase in fuel consumption, the aerodynamics of the car must not be disturbed. A roof rack, ridiculous sports body kits and collective farm rear wings can significantly distort the passage of air flows through the car body. Turbulent eddies arise behind the stern, a zone of reduced pressure is formed, which sucks the machine back, preventing its movement. Now all cars are blown in wind tunnels, where engineers try to arrange the body so that the air flow is dumped and chaotic already far behind the stern. The sedan is considered to be the most optimal body type in terms of aerodynamics.

All in all, these simple tips can help you save on gas. Tests of domestic magazines have shown that, thanks to a set of these rules, it is possible to reduce the consumption of a 1.6-liter naturally-aspirated engine on C-class cars with a manual gearbox and with front-wheel drive to 3.5-4 liters of gasoline per 100 km of run. True, driving so economically is a lot of work.

Economical driving style

Starting the engine without using overgas.

Modern engines have a direct fuel injection system and over-gasing before starting leads to an increase in fuel consumption, which negatively affects the condition of the engine. Such a start of the power unit should only be used on a carburetor engine in order to supply fuel to the carburetor working chamber.

Warming up the engine while driving.

Modern lubricants are made with high-quality additives, which have the ability to heat up faster without losing their technical characteristics. Therefore, before driving, even in cold weather, about one minute is enough to warm up the engine.

Smooth start of movement.

It is necessary to start driving calmly and confidently, avoiding sharp acceleration, since with fast acceleration there will definitely be an increased fuel consumption.

Tracking tachometer readings.

Fuel consumption depends on the speed, the lower the speed of the power unit, the lower the consumption. On average, for the overwhelming number of 3000 rpm engines. fuel consumption is almost 3 times higher than at 1500 rpm. The best mode is considered to be movement in the range of 2000-2500 rpm.

Driving without sudden accelerations.

Rapid changes in vehicle speed require an increased fuel consumption of about 20%. Therefore, if the traffic situation does not require such decisions, it is better to choose a quiet driving mode. In this case, the most economical movement is considered to be in maximum gear at the above engine speeds. When changing gears, avoid running the engine at high speeds.

Passage of city traffic lights.

In urban conditions, it is necessary to try to pass traffic lights without stopping, especially if the route is well known. If you do not have time to pass the permit signal, you need to slow down and smoothly reach the stop in front of the traffic light. The best option would be if during this time the red light goes out and the green light turns on again.

Many modern cars have a Stop-Start system, which automatically saves fuel when stopped. In cases where the car is not equipped with such a complex, then it is better to turn off the engine when parked for more than one minute, since frequent starting of the engine is an unfavorable moment in the operation of the power unit, in which there is a loss of the quality of the engine oil. The engine itself in idle mode consumes more fuel than when starting and driving.

Choosing the best distance when driving in heavy traffic.

If your vehicle is driving in heavy traffic, you should choose a distance and speed that will help you avoid frequent use of the brakes. After a sharp decrease in speed, it will be necessary to gain it again in the future, which will lead to the consumption of additional fuel.

Travel at optimal speed.

For all cars, there is such a thing as optimal speed. This speed is considered to be the minimum one that allows the vehicle to move in the highest gear. Driving using these parameters will ensure minimum fuel consumption, especially on country roads. In most cases, the range of this speed is 90-100 km / h. Driving at high speed increases air resistance, requires additional efforts from the engine and, as a result, an increase in fuel consumption.

Choice of convenient parking.

When parking a car, especially if the car is used on a daily basis, it is necessary, if possible, to choose a method that will exclude movement when leaving or reversing. Reversing maneuvers are considered more difficult and require more fuel.

Using engine braking.

If the traffic situation permits, decelerate the vehicle with the help of the power unit. Such braking will gradually reduce the used motor power with a decrease in consumption. When using brakes, the engine runs for a certain time in conditions of excessive power and, accordingly, consumes more fuel.

Technical condition

Tire pressure monitoring.

Maintaining the correct pressure in the tires of the car is an important point in economical driving. A decrease in pressure increases the contact area between the tire and the road. This increases friction, which automatically leads to increased fuel consumption and tire wear. The technical parameters of tires always indicate the permissible pressure range and for more economical operation, you must try to maintain the upper bar of this range.

Monitoring the condition of tires.

As the mileage progresses, wheel wear increases, which reduces the size of the tread and, as a result, increases rolling, with a subsequent increase in fuel consumption. At the same time, the wear itself can occur unevenly, therefore it is important, in accordance with the established norms for a particular brand of tires, to rearrange the wheels in accordance with the scheme of the car.

Compliance with the frequency of replacing the air filter.

Failure to change the air filter leads to the formation of a poor-quality working mixture, which reduces engine power. To compensate for this reduction, additional fuel consumption is required. In addition, contaminated air entering the engine increases wear. The frequency of changing the air filter is set by the manufacturer’s regulations, but an adjustment must be made taking into account the operating conditions of the car. If such conditions differ from normal, namely, the car is used only in the city or on dusty rural roads, it is necessary to adjust the filter replacement period. Usually it is cut in half.

Use of quality engine oil.

High-quality engine lubrication effectively reduces the friction force between engine elements, performs better cooling, which reduces power losses and, as a result, reduces fuel consumption. The frequency of changing the engine oil is also established by the regulations and is approximately from 10 to 15 thousand km, while, as with the air filter, it is necessary to adjust the replacement depending on the operating conditions of the car. In addition, when performing a change, it is important to change the oil filter, since it is in it that all metal particles are removed, which, in the absence of a replacement, will increase the friction force in the engine and increase wear. The most effective are modern synthetic oils, certain types of such oils can save up to 7.5% of fuel.

Monitor the weight.

With an increase in the weight of the car by about 100 kg, the fuel consumption increases by 7-10%, therefore it is necessary to monitor the optimal load and, depending on the trip, use only the necessary things. In addition, a full fuel tank (60 liters) adds 45 kg to the vehicle’s weight, so it is best to keep the amount of fuel between a quarter and a half of the tank volume, but be sure to take into account the possibility of refueling. Driving with an almost empty tank can damage the fuel pump.

Car aerodynamics control.

The roof rack mounted on the car roof increases the aerodynamic drag, which requires additional fuel consumption to overcome. On average, an empty trunk can add up to 5% more fuel consumption. Therefore, if there is no need, the trunk must be dismantled. Also, additional resistance can be created by air currents when the windows of the passenger compartment are open, various decorative elements and body kits installed on the body, as well as extended rims.

Timely replacement of spark plugs.

Three little-known ways to significantly save fuel in traffic jams. How to save on gasoline (no nonsense about magnets and additives).

The completeness of gasoline combustion depends on the operation of the spark plugs. If the gasoline does not completely burn out, its consumption automatically increases and the engine power decreases. To compensate for such a drop, additional fuel is needed, therefore, it is necessary to observe the frequency of replacing the candles, and sometimes it is better to do this earlier, since candles with a large operating time also do not provide high-quality ignition.

Financial ways to reduce costs

  • Track the price of fuel at gas stations of various companies. At the same time, choose a gas station for refueling with the best price-quality ratio.
  • Purchase and refuel using bonus cards from various fuel manufacturers.
  • Pay for fuel using plastic cards, which have the function of returning a certain percentage for the completed purchase.
  • Carry out refueling at night and in the evening, since a number of gas stations during this period apply a certain discount.
  • Try to think over the route and time of your trips, which will help to avoid traffic jams on city roads, shorten the travel time, and choose a short distance.

Causes of excessive fuel consumption

The main reasons for the high fuel consumption lie in the technical condition of the vehicle. If it is in an unsatisfactory technical condition, then no tricks (economical driving, the use of various additives and fuel economy) will help solve this problem. Among the large number of breakdowns that can contribute to an increase in fuel consumption, the most common malfunctions are:

  • the power unit (the spark plug is out of order, the timing belt is stretched, the ignition is out of order, etc.);
  • one of the sensors that control the operation of the fuel injection system (lambda probe, mass air flow sensor, oxygen sensor, etc.);
  • suspension, braking system or transmission.
  • no less often there is the use of filters clogged with dirt: air and / or fuel;
  • excessive consumption of gasoline or diesel is also facilitated by the abuse of prolonged warming up of the power unit. In practice, you shouldn’t warm up the car engine for more than three minutes. This time is quite enough to disperse the engine oil in all units and friction pairs. After 3 minutes, you can start driving at low speeds (up to 2000 rpm) – while the fuel consumption will be less, and the engine will warm up faster;
  • in the matter of fuel economy, not the last place is taken by the pressure in the tires of the car, which must be regularly monitored and maintained within the limits specified in the manual for its operation. The type (winter, summer, all-season), tread pattern and the amount of wear of the tires installed on the car are also important;
  • significantly affects the consumption of gasoline or diesel and an incorrectly set camber / toe angle. It is recommended to check it every 15 … 20 thousand kilometers;
  • Excessive enthusiasm for the outer body kit (tuning) also leads to an increased fuel consumption. This is especially true for elements made by handicraft methods. But the regular trunk, “fly swatter”, overhead arches and other body kit elements significantly worsen the aerodynamics of the car, which also leads to its overspending;
  • worsen the aerodynamics of the car and open windows, especially when driving at a speed of more than 60 km / h;
  • the driving style of each individual driver cannot be discounted. An overly aggressive driving style, with a constant sharp set of speed and no less sharp braking, causes an unreasonably high consumption of gasoline or diesel;

In addition, if, for no apparent reason, the consumption of gasoline / diesel has increased significantly, it is necessary to visit a licensed service station, where, using special devices, experienced specialists will be able to identify and eliminate the malfunction.

Ways to reduce fuel consumption

In practice, there are a large number of various techniques that allow you to maintain the standard fuel consumption for a particular car. At the same time, the most important condition for ensuring its optimal value, many experts and specialists consider the maintenance of the car in good condition.

Tips from experienced drivers and auto experts will tell you how to reduce fuel consumption. In their opinion, getting rid of such problems will help:

  • refusal to use additives that increase the octane number, instead of gasoline recommended by the car manufacturer;
  • turning off the stove when the engine warms up in the cold season – this will reduce fuel consumption by about 5%;
  • replacement of the air filter after 10 … 15 thousand kilometers – especially in summer, when there is a lot of dust on the road (fuel savings can be up to 10%);
  • replacement of spark plugs at least every 15 thousand kilometers, which will give about 10% fuel economy;
  • regular monitoring of tire pressure (reduction of fuel consumption up to 7%);
  • lack of a trunk (box) on the roof of the car and other body kit elements;
  • braking by the engine, not the brake pedal;
  • Regularly check the correct setting of the camber / toe angles. At the same time, in addition to saving fuel, which can reach 15%, long-term tire operation will also be ensured.

Note: the percentage of fuel savings indicated in the text is nothing more than an increase in its standard consumption if the recommendations are not followed.

In addition, there are fuel savers to help you avoid dramatic increases in fuel consumption. Among them, the most effective means are:

  • Magnetic Fuel Free and Fuel Saver

Magnetic savers are installed on the fuel supply hose in the immediate vicinity of the units for supplying it to the cylinders (injector, carburetor, high pressure fuel pump). Their principle of operation is based on the influence of the magnetic field, which is created by powerful neodymium magnets (an alloy of boron, neodymium and iron), on the molecular structure of the fuel. At the moment of crossing the magnetic lines of force, its structure changes, its surface tension decreases, the solubility of oxygen increases, the polarization of molecules increases, the burning rate increases, and the detonation resistance and other properties of the fuel decrease. Under its influence, the combustion of fuel in the combustion chamber becomes significantly more efficient, and the amount of exhaust gases decreases. According to the manufacturers of these devices, fuel consumption is reduced by about 20%,

  • Fuel Saver Fuel Shark

Structurally, Fuel Shark is a large-capacity electrolytic capacitor, which, when connected to the vehicle’s on-board network, reduces the load on the vehicle’s battery. At the same time, the operation of the power supply system is leveled, which ensures a stable supply of voltage to the spark plugs and a high-quality spark. As a result, the fuel burns more efficiently. The economizer is installed in the cigarette lighter socket and, according to the manufacturers, saves up to 30% of fuel.

  • Cavitator

The principle of operation of the cavitator is to convert liquid fuel into a gaseous state. Structurally, it is a tube of variable cross-section, which is installed after the gas pump. It is known that fuel at the molecular level has long chains of molecules, which are characterized by low combustion characteristics. With the help of a cavitator, they are destroyed, which contributes to a faster and more efficient combustion of fuel. In general, the economic effect is achieved due to the fact that while maintaining the existing dynamic parameters, the car consumes significantly less fuel. In addition, the cavitator separates heavy fractions from the fuel and is equipped with an additional filter. Therefore, the mixture entering the combustion chambers is highly purified,

  • ATW impulse device

The ATW impulse device is designed for all types of vehicles equipped with a 12-volt battery and is connected directly to its terminals. The pulses generated by the device contribute to the accelerated charging of the battery, so that the generator spends much less time and power on this process. This in turn reduces the load on the engine and reduces the fuel injection time. In accordance with the technical characteristics declared by the manufacturer, fuel consumption is reduced by 10 … 20%. The expediency of using the device with worn-out batteries is especially noted. During operation, ATW impulse not only saves fuel, but also protects (restores) the battery plates, increasing its service life 2 … 3 times.

washing gasolines

According to advertisements, switching to gasolines with increased cleaning power can save the owner as much as 10% in fuel. Well, it’s true that gasolines like this can actually reduce fuel consumption. But this is not the whole truth.

According to advertisements, switching to gasolines with increased cleaning power can save the owner as much as 10% in fuel. Well, it’s true that gasolines like this can actually reduce fuel consumption. But this is not the whole truth.

The fact is that such advertising statements refer exclusively to “staged” experiments. And if we compare the behavior of a clean motor, filled with 98th Ultimate gasoline, Ecto, etc., with its grimy colleague, who has consumed only the usual 95th all his life, and even without any washing abilities, then the effect may turn out to be just that. However, as the dirt is washed out, the difference will melt before our eyes and ultimately come down to a different engine response to gasoline with different octane numbers. In other words, two brand new engines, fueled with detergent and regular gasoline with the same octane number, will behave almost the same – the difference can be caught only at the stands.

As for talking about comparing, for example, 92s and 95s, you should not count on real savings. In addition, Europe has already abandoned the 92s.

Motor oil

Three little-known ways to significantly save fuel in traffic jams. How to save on gasoline (no nonsense about magnets and additives).A reduction in consumption is possible, but it is usually compared with obsolete mineral oils.

A reduction in consumption is possible, but it is usually compared with obsolete mineral oils.

You can’t save much here. Almost all modern oils (above SL) can be considered energy-saving, and therefore we can only talk about some kind of gain in comparison with the ancient mineral water 15W-40 of the SJ class. However, the figures in this case can be quite good – 5-6 percent. And in certain modes – for example, minimum stable idle – up to 10%. True, recently they have been trying hard to accustom us to 0W-20 oils – they say, the savings are obvious: oil is like water. Well, in winter, yes, it is possible. But in the summer there can be troubles.

spark plug

Three little-known ways to significantly save fuel in traffic jams. How to save on gasoline (no nonsense about magnets and additives).

With candles, everything is clear. The energy of the spark discharge gives an impetus to the flame front, the speed of propagation of which directly affects the economy, power, ecology, etc. The speed of flame propagation depends on the temperature squared, and the temperature in the initial phase, when the flame is still “sitting” in the interelectrode space, on the discharge energy. This dependence is especially noticeable when ignition is difficult – at low voltage in the primary ignition circuit, at minimum idle speed and low load modes, when a lot of residual gases remain in the chamber. Our tests have shown that a well-matched pair of spark plug plus wire can improve the efficiency of the motor by 2-3%.

Recall that iridium and platinum candles live three to four times longer than usual. In this case, the refractory materials of the electrodes can sharply reduce their size, increasing the electric field strength in the interelectrode space. This increases the stability and stability of the discharge and allows the spark gap to be increased. At the same time, a more powerful discharge improves the cleaning of the electrodes and insulator – therefore, the candle works better in dirty conditions.

A lot also depends on the gap in the candles. The larger the gap, the larger the spark, and hence the size of the initial ignition source. And the speed of propagation of the flame front strongly depends on the geometric size of the initial ignition zone. But as the gap increases, so does its resistance. This means that the breakdown will occur at a higher voltage in the secondary circuit. And it is important that this voltage is generally enough for a breakdown! Therefore, for injection engines, in which the voltage in the secondary circuit is higher than that of carburetor engines, and the gaps are recommended to be set large. In addition, with an increase in the gap, the likelihood of shunting the electrodes by all sorts of “soot bridges” decreases – this is also important.

From candles to wires. Owners of old women should know that good wires regularly introduce their five cents into economic theory. The quality and tightness of the contact tip, the tightness of the cap, the value of the distributed resistance, as well as the length of the wire play a role here. The latter circumstance is especially interesting. Almost all wire manufacturers offer the consumer products of different lengths – for ease of installation. However, in this case, the spark discharges have to cover different distances, and therefore the uniformity of the ICE operation is disturbed. If the wires had zero resistance, then, of course, there would be no difference, but, according to ISO standards, one should fit into the radio interference tolerances. Therefore, resistance is present both in the spark plugs and in the wires, and the total resistance of the pair is not monitored by anyone.

Air filter

Three little-known ways to significantly save fuel in traffic jams. How to save on gasoline (no nonsense about magnets and additives).Type Does the fuel consumption change depending on the type of oil filter or air filter? Yes, it can change, but not very significantly: within the same percentage units. Moreover, the type of filter affects much less than its actual state. The resistance of the air filter is especially important. The larger it is, the worse is the filling of the cylinders, and this immediately affects the fuel consumption. And depending on the manufacturer of the air filters, their resistance can change almost two to three times.

Oil filters also affect consumption, but relatively little. And here the filter size influences to a certain extent. After all, it acts as a small oil cooler for the engine, which can contain up to 10–20% of the total oil volume.

Gas filling

Gas supporters defend it as fiercely as opponents criticize it.

Gas supporters defend it as fiercely as opponents criticize it.

The apologists for gas fuel are perplexed: why, they say, do we not switch to gas with the whole crowd, if the savings are obvious? Here, not just a few percent shine, but tens. Yes, this is true: everyone can switch to gas even tomorrow. However, there are also disadvantages. The machine will lose its agility, lose its former trunk volume, it will become worse to start up in winter. In addition, the network of gas stations is poorly developed. Finally, you will have to refuel more often when driving on gas.

Which is better: compressed or liquefied? Compressed is methane, liquefied is a propane-butane mixture. Liquefied – significantly more calories, and the cylinders for its storage are more compact. But it is heavier than air, and therefore, if you store a car in the garage, there can be problems: when it leaks, it does not rise up and is not ventilated like methane, but accumulates below. He loves pits and all kinds of cellars: it is not easy to pump him out of there. And this is a fire hazard. Such cars are often not allowed into underground parking lots.

Fuel equipment for liquefied gas is simpler and cheaper, and there are much more refueling – this is also an argument in its favor. Compressed gas is cheaper, less fire hazardous, and more environmentally friendly – after all, it is methane, and it burns better than a propane-butane mixture.

Let us express ourselves carefully: never fill in all sorts of drugs at least in the warranty machines. At the end of the warranty period – experiment with your health. As for the Zarulevsky tests, in some cases, a small fuel economy was actually achieved – within a couple of percent.

We have never recorded the promised 8-10 percent or more. We note right away that the promised effect can usually be used to judge the seriousness of the authors of the idea. Only charlatans promise savings of 20, 30 and more percent. In any case, according to our experience, no one has yet been able to dig out tens of percent of savings hidden inside the well-oiled and fine-tuned internal combustion engine. If we see, we’ll let you know right away.

Organizational Methods to Reduce Fuel Consumption on Diesel

There are several organizational tips that will allow you to more economically consume fuel on a diesel car only through its rational operation.

  1. Check the tire pressure and bring it up to the maximum admissible value. Low tire pressure increases the contact area between the wheel and the road, which increases the energy consumption of the engine to overcome friction in this contact patch. Approach this procedure with caution: Over-inflated tires reduce traction.
  2. Try to drive in the engine speed range near the highest torque. Do not crank the engine up to the red zone and do not “choke” the motor with low revs. It is a known fact: the efficiency of a diesel engine varies depending on its operating mode. And the maximum amount of burned fuel is converted into kinetic energy on the crankshaft precisely in the rpm range corresponding to the maximum torque.
  3. Use auto electrical appliances to a minimum. Enable them only when necessary. For example, the habit of driving with the stove turned on at maximum in winter and with the windows ajar will add about 3-5% to fuel consumption.
  4. Warm up the engine to at least 60 ° C in winter before driving. The network contains the results of experiments on the fuel consumption of a diesel engine when driving with a warm engine and starting immediately after starting. Warming up at idle speed will burn no more than 100-150 grams of fuel. While driving the first 5-10 minutes on a cold engine will increase diesel consumption by 20-30%. That will result in an overrun of 500-800 grams each time you start driving immediately after starting.

This fairly simple and affordable set of tips will help you cut your diesel engine fuel consumption by 10-20%.

The main reasons for the increase in diesel fuel consumption

The main reasons for the increased fuel consumption on a diesel engine and the occurrence of smoky exhaust include:

  • lack of tightness of the power supply system;
  • clogged air filter;
  • clogging of the drain fuel line;
  • contamination or wear of nozzles;
  • violation of the value of the lead angle of the fuel injection depending on the speed;
  • valve clearances;
  • failure of the high pressure fuel pump.

Some of these reasons simultaneously lead to a decrease in power, a deterioration in the dynamics of acceleration, an unstable operation of the engine at idle speed, and problems with starting.

If diesel fuel is needed for heating

Consider thermal insulation. If you install heating in an unprepared “box” of the house without thermal insulation, you will waste up to 50% of the fuel. Take care of good insulation in advance. It is advisable to mount it outside the house – so the thermal conductivity of the walls will decrease, and the heating system will consume 10-50% less fuel.

Install an automatic boiler. Automatic boilers for diesel fuel are more profitable than conventional ones. They control the temperature of the coolant in the heating system and regulate the supply of fuel, saving it. If you install a conventional boiler without automation, you will have to constantly switch modes on it. Continuous operation at high power will increase fuel consumption by 20-30%.

Install a coaxial flue. It meets fire safety requirements, is easier to mount than a brick analogue and retains heat inside the premises. Less fuel is consumed: the room is kept at a good temperature.

Use new radiators. They are easier to install, lighter in weight and have high heat dissipation. Aluminum radiators heat up quickly and do not cool down for a long time if the preset temperature is maintained in the heating system.

Adjust the nozzles. Many don’t. Correct adjustment of the injectors can save 2-3 liters of diesel fuel per day. Just call the foreman and he will carry out the adjustment.

Place the supply container warm. Use an underground tank or place a container in a heated room. So diesel fuel will retain its technical characteristics, maintain optimal viscosity, therefore, fuel consumption will decrease.

Install new doors and windows. Window and door openings account for up to 60% of heat loss, therefore, thermal insulation alone will not be enough for great savings. Choose wood or plastic double or triple glazing and door panels with additional thermal insulation.

If diesel fuel is needed for a car

Do not step on the gas. Of course, it’s not worth driving at a speed of 20 km / h, but do not exceed the speed. You should not drive around the city at a speed of 100-120 km / h – the car consumes more fuel if the driver constantly presses the brake pedal (to brake in front of the intersection), and then strongly presses on the gas.

Monitor tire pressure. There is no need to do with balancing – the correct tire pressure increases the speed of the car, allows it to move faster with the same fuel consumption. Tire pressure adjustment reduces fuel consumption by 10-12% at the same distance. After all, reducing the pressure by one tenth increases the flow rate by 5%.

Avoid sudden acceleration. Do not accelerate at traffic lights, before leaving the yard or on the highway. Develop your smooth driving style. Rapid acceleration increases fuel consumption, so you will save diesel fuel when driving smoothly.

Do not turn on appliances. If possible, you do not need to turn on the stove, seat heating, heated glass, halogen headlights and other electrical equipment. When turned on, it increases the consumption of diesel fuel, and when the electrical equipment is turned off, the fuel consumption will decrease.

Clean the trunk. If there are a lot of unnecessary things in it, put them out. A full trunk increases the weight of the car, which means it reduces its aerodynamic performance. Consequently, the fuel consumption is increased.

Do not warm up the car. Modern motors do not need this – 2-4 seconds are enough for them. Maximum – warm up the car for 30-60 seconds to warm up the interior. If you have an old car, it is worth warming it up before every ride.

Don’t tune your car. If you want to install a spoiler, additional mirrors or other type of tuning, remember that this will reduce aerodynamic performance. A tuned car will consume more diesel than a standard car at the same distance, at the same speeds.

Go through the inspection. Regular vehicle checks and minor troubleshooting improve the performance of the entire undercarriage. This increases the diesel fuel economy by up to 20%.

Use quality diesel fuel. High-quality fuel reduces consumption by only 2-3%, less often up to 10%, but it increases the service life of the undercarriage and reduces vehicle maintenance costs by up to 20%.

Do additives help you save money?

Additives for diesel fuel have appeared on the market, which, judging by the assurances of manufacturers, reduce fuel consumption. Such funds are similar to dietary supplements: they are not prohibited by the state, allowed for sale, but their effect has not been proven. Therefore, such additives are a waste of money. It is better to follow simple tips – together they can save up to 50% of diesel fuel, which will significantly improve the state of the budget.
