| The harder car, the more fuel it eats. |
|
Regularly check the air pressure on tires. We recommend 1 time in 2 weeks. Winter fuel consumption increases from 5 to 10% |
|
| "Cold" Motor Very voracious, this is a well-known fact. |
| Runger on the roof of the car increases aerodynamic resistance - Increases fuel consumption. |
| Jump the engine at stops for more than 5 minutes. |
| The quieter you go, the further you'll get! In our case: you go quiet - the flow rate is less! |
|
Rog quietly - Do not need to sharply accelerate and brake sharply, to then dial the speed again! Economic acceleration - It is smooth overclocking, not a slow. For new cars, fuel consumption is always slightly higher than the norm - the first 10-15 thousand km is normal. |

Movement on the transmission and braking engine will give great savings than the movement on neutral transmission for modern car. The state of the road surface has an impact on fuel consumption - increases: the road with potholes, wet road, slippery ... Move reduced transmission, sliding, tonve |
Miscellaneous of what motorist does not care about the issue of the fuel consumption of his pet. Even if you take "Machines Twins": the car of one brand, model, in one configuration, from different owners the fuel consumption will be different. There are a lot of questions about fuel consumption. The reasons high expellation fuel? What does fuel consumption depend on? How to reduce fuel consumption? - Let's try to figure out today together.
Fuel consumption mainly depends on driving style (driving manners), operating conditions applied fuel lubricants (GSM).
Optimal vehicle fuel consumption.
- constantly control the air pressure in the tires (tire pressure in the tires Some manufacturers indicate the table on the lid of the bulk neck fuel tank);
- warming the engine in motion;
- avoid frequent and sharp acceleration;
- switching gear, providing engine operation at a frequency of 2/3 of the maximum frequency;
- regularly carry out prescribed maintenance;
- do not carry an unnecessary ballast in the car (the more your car weighs, the more fuel consumption);
- do not install additional external equipment, worsening the aerodynamic characteristics of the car;
- refueling with high-quality fuel prescribed by the manufacturer.
Fuel consumption increases significantly when moving in large cities, short distances (the engine does not reach the operating temperature), driving with a trailer, driving around the mountainous area. Season of the year - winter fuel consumption is greater than in summer: winter tires, long-term heating, car heating, increased time of use of light instruments, deterioration of the state of the road surface, etc.
How does the air conditioner affect the fuel consumption?
Contrary to the general opinion, the air conditioning system of a modern car does not cause a significant increase in fuel consumption under standard conditions, but if for you 3 - 5% is essential, try to do without air conditioning. At the same time in the heat when the air conditioner works on full power Fuel consumption due to air conditioner increases to 10%. Cause - When using the air conditioning system, part of the engine power is spent on bringing the air conditioner to the operation of the larger, the more consumption.
The color of the car affects fuel consumption!
Yes, you are not mistaken! Cars are more economical if painted in light color - proven by researchers from the California city of Berkeley.
Scientists took two identical car Color painted in black and silver and generated research - environmental influences (sun) at work car conditioner. As a result, it was found that the temperature in the salon of a silver car on average by 5-6 degrees is lower than in the black cabin, respectively, the cooling of the light vehicle salon was spent by 13% less than the cooling of black. Due to the smaller energy consumption during the operation of the air conditioner, the fuel consumption of a silver car is 1.1% less than black.
How does the wheel width affect fuel consumption?
Wide wheels create aerodynamic resistance much more than narrow. Accordingly, fuel consumption increases and vice versa. Optimal option - The dimension of disks and tires recommended by the manufacturer.
Regularly holding maintenance The car will significantly reduce fuel consumption.
To reflection - an increase in fuel consumption:
- non-timely replaced air filter up to 10%;
- non-working spark plugs up to 10%;
- scored catalyst up to 10%;
- incorrectly installed wheel angles up to 5%;
- the pressure drop in tires by 0.4 atm is below the norm to 10%.
In the article, we will tell about the main reasons why gasoline consumption increases and how to avoid it.
With the current increase in fuel prices, each driver starts to save and remember the reasons why fuel consumption increases. So, at some refills for the liter A-95 now give an average of 36 rubles. They say, on this prices will not stop. Some filling stations Sell \u200b\u200bpoor-quality gasoline, who with experience will immediately understand what the snag. In such cases or octane number Raised with special additives or give gasoline, which does not correspond to the stated brand.

1. The main reason consider the wrong operation of electronics, which manages the engineOften it is on new foreign cars. As a result, most often the cause becomes faulty sensorsdesigned to optimally calculate the mixture of air and fuel. Such sensors can be attributed, oxygen sensor, temperature sensors, a throttle valve sensor, the sensor that is responsible for controlling air flow, the latter often fails if it is not possible to clean the air filter for a long time. It is usually due to the error of these sensors in varying depends, which will be the "rich" or "poor" mixture. As a result, this will lead to power loss and increase gasoline consumption. Considering that the technologies are modern, it is impossible to determine their eye diagnostics, it is worth going to a special service center or sort out each sensor individually.
2. The second reason is the pressure in the fuel system when it is uneven. It is usually or lower or higher. Often because of the reduced pressure is lost the power of the unit, and in the car with automatic gearbox Increases engine operation while high revolutionsThe result is increasing and fuel consumption. Often, here are the malfunction of the engine injector. If you say bad fuel And not to look at the time, the efficiency of the unit will decrease in proportion to the increase in fuel consumption. Therefore, look carefully, so as not to be clogged, as cleaning will be a long procedure and not cheap, the cost of about 2000 rubles, it all depends on the brand and engine of the car.
3. An important factor of excessive fuel consumption is an air filter. When it is scored and an insufficient number of outdoor air enters the engine, the so-called "air starvation" occurs in the unit. Therefore, not be lazy, from time to time to watch and clean it. This is especially true in the summer season, if you often have to ride on a country road.
4. Next, in the course of the combustion of the fuel, we have a catalyst, as in any car, with time it may turn, or in general collapses. Each car is a different structure, but the main thing is the stronger it is scored, the more fuel consumption. The reason often happens a rich combustible mixture. In the same way, the engine power will be lost proportionally, or differently, as they say, the engine is given, as the exhaust gases will not be able to sell. From time to time listen to the sound of the catalyst, and on its condition.
The main physical reasons for increased gasoline consumption
The main reason is distinguished the temperature, both the engine and the environment, that is, depends on the season (winter / summer). Since gasoline has a property evaporate, then in summer, especially in the south, with a very hot engine, the fuel is simply evaporated from the fuel system. As for the temperature of the engine, the optimal for work is considered to be somewhere 80? 90 degrees Celsius.
The reverse side when the engine does not warm as it should, and you eat on the sample, it only concerns carburetor engines. In this case, consumption increases significantly, in fuel system There is little air and a lot of gasoline.
Consumption will increase somewhere by 20% than usual, and if the engine warmed up and you forgot to close the subsidation, then the flow will grow by 50%, or even more, so it is worth watching this.
An important factor is the use of air conditioner in summer period, I think that every driver knows, when using such pleasure, the load on the engine increases, respectively on-board computerBy keeping power, it starts to increase fuel consumption.
It is also often said about the streamliness of the car, the ride style, about which gearbox is used (automatic or mechanical), there is a trailer or not. Not to tell all factors, in this case you just need to have practice and experience.

Five reasons affecting fuel consumption by car
Argonne National Laboratory, US Department of Energy Research Center, unexpectedly decided to talk about five main factors noticeably affecting fuel consumption by car. Considering some of them, you can save a couple of liters of gasoline, driving a hundred kilometers. All factors are well known to almost all drivers, but the reason for them once again recall (and at the same time a little physics) is really good.

Pressure vapor fuel
Gasoline is a mixture of light hydrocarbons with different boiling temperatures. The better the fuel evaporates, the faster the engine starts and the more fuel is consumed during the ride. For this reason, fuel producers combine the composition of the fuel for winter and for summer, mixing hydrocarbons with different boiling points. Light gasoline fractions evaporate faster, but during combustion, fewer energy is distinguished. Because of this, the engine efficiency is reduced, and fuel consumption increases.
Since the cost of obtaining hydrocarbons with low boiling point is significantly lower than fractions with high boiling point, fuel manufacturers try to increase their content in the combustion.
In winter, gasoline with a high content of lung hydrocarbons allows you to quickly run the engine. However, in summer, such fuel at high air temperature is actively evaporated, polluting environment. Reducing the share of hydrocarbon compounds with low boiling point makes it possible to increase the energy return of fuel, which means to improve the engine performance and reduce gasoline consumption.
Friction
The fuel consumption is significantly affected by friction. Researchers of the Okride division of the Argonne National Laboratory conducted an experiment. They measured fuel consumption by several cars at a speed of 80 kilometers per hour. Then they measured the flow and with more high speeds. It turned out that an increase in speed by 16 kilometers per hour reduces the distance that can be driving on one tank by 12 percent. The growth rate of another 16 kilometers per hour will reduce the distance by 15 percent.
When driving with a constant acceleration, part of the engine power is spent on overcoming the friction of the wheels about the road, and the higher the speed, the more power spent. The researchers calculated that the speed at 130 kilometers per hour is spent eight times more engine power than when moving at a speed of 65 kilometers per hour. Hence the conclusion that more speed The car, the greater the fuel will be burned with the engine.
Drag
The shape of the car body also affects fuel consumption. The more "sailing" car has a nasal part, the more with a large air resistance in motion it will face. In order to better understand the action of the windshield, sufficient while driving the hand into the window. If you turn it with palm perpendicular to the earth, you can feel how the air will start to delay it back. Air resistance will decrease if the palm is laid parallel to the ground.
Today, automakers are trying to design car hulls in such a way that during the movement they created as smaller resistance. The machines with the most streamlined forms of the body are spent less engine power to overcome air resistance, which means it is consumed less than fuel.
Inertia
The concept of inertia means the ability of any object to maintain its stability with respect to external influence. Inertia depends on the mass of the object. In practice, this means that the heavier car, the higher engine It is dispersed and the slower the car will stop after the driver removes his foot from the gas pedal. In this case, the intensity of overclocking also affects the power consumption of the engine.
The faster the heavy car needs to be dispersed, the more fuel will be spent on maintaining the engine required for this power. If the driver wants to save, then he needs to touch the traffic light as smaller as possible. Overclocking will not be "sports", but fuel will spend less. After the overclocking, it is not necessary to put the gas pedal to the next traffic light. You can minimize or let go of the pedal - the car will continue to move along the inertia slightly slowing down. Fuel will be spent only on maintaining the engine operation.
Round resistance
In addition to friction tires about the road fabric, there is an internal resistance of the rolling wheel. The larger the wheel is, the more the engine power is required to overcome resistance, and vice versa. Ideal from the point of view of fuel efficiency is an absolutely solid wheel. However, when developing tires, it is necessary to consider and combine several factors. For example, a solid wheel due to low resistance is worse inhibits, but remarkably transfers vibrations to the suspension.
Manufacturers calculate rigidity of rubber for wheels depending on the type of car to which they will be installed. On the sports cars There is more rigid tires, since it is minimally rolling resistance. This means that the engine of the machine will spend less energy to overcome rolling resistance and the car is being worked out faster. For ordinary cars The rubber is used softer - it allows you to make part of the vibrations, but it has a small rolling resistance.
To reduce fuel consumption, drivers should comply with the manufacturer's guidelines for tire types and pressure in them - the higher the pressure, the tougher wheel.
Bonuses
In addition to the main five factors affecting fuel consumption, the Argonne National Laboratory called another one. This is the ambient temperature. In the heat, drivers usually include air conditioners (if, of course, their cars are equipped with such systems), thereby increasing the consumption of fuel. The fact is that the operation of the air conditioner is also consumed part of the engine power, since it drives the main units of this device.
Researchers of the Argonne National Laboratory noted that if it is not possible to abandon the use of the air conditioner, it is worth it at least turn it off if you need to sharp overclocking. The light air conditioned power can be very useful.
Regular increase in gasoline prices forces car owners to think about reducing fuel consumption. The article tells about five simple waysHelp save gasoline. 
Top 5 factors
Engine heating and car technical condition
The movement on the immentable engine speeds up the wear of parts, has an impact on the stability of its operation. The warm-up temperature is about 80 degrees. Close to this temperature you can start moving, on the move the engine warms up faster.
The machine needs regular diagnostics at maintenance stations (service station). There will be checked the gaps of the engine valves, the ignition system, collapse / wheel alignment, tire pressure, fuel system.
Reduced tire pressure increases gasoline consumption by 3%. This occurs due to the fact that the area of \u200b\u200bcontact of the surface of the tires is increasing road coating. Optimal pressure of 2 atm. Checking pressure is needed at least once a month. Shin pumping is also dangerous if you have to move on icing or wet road.
Machinery machine and air filter
Inclusion of the heating of the cabin, seats, air conditioning, overall lights, near I. far Light Increases gasoline consumption of approximately 5%. If all the device enable simultaneously fuel consumption will increase by more than 10%.
Middle-end light enhances fuel consumption by 0.1 liters (100 km). Using in hot air conditioner at full capacity increases fuel consumption by 15%. If you drive at a speed of 60 km / h with open windows, it will increase fuel consumption by 4%.
This is due to the fact that air resistance increases. It is necessary to control the condition of the air filter.
The air is mixed with fuel to improve the combustion of the working mixture in the engine cylinders, before this it passes the cleaning (dust, dirt) in air filter. If it closes, the air mixture will contain little air and excess fuel, which leads to increased gasoline consumption. The filter replacement period is specified in technical Regulations For car maintenance. If you often travel along the dirt roads, then it is necessary to change it more often.
