To date, there has been such a situation in our country that the prices for automotive fuels grow almost in geometric progression. And ways to reduce its consumption are relevant than ever. Let us analyze in detail what methods can reduce car fuel consumption.

Calculation of fuel consumption, calculation method

Each car owner needs to know the accurate fuel consumption of his car. And satisfy your curiosity is not the only reason. For example, when traveling to the outback, not knowledge of the accurate fuel consumption can lead to a "walk with Kanishystroe" to the nearest gas station. Knowledge of accurate fuel consumption capable of solving many vital issues.
Of course, fuel consumption can be found in the car documentation, but the fact that the data specified in it is usually not true. The fact is that the manufacturer indicates the flow rate in the so-called "normal" mode, but the concept of "normal" can differ significantly.
Owning a car with the onboard computer had more luck. They do not need to make any calculations. On-board computer, and so will all the necessary data, including vehicle and fuel consumption per 100 km.

Important! The problem is to determine the exact fuel that is never precisely known how much fuel remains in the fuel tank. And the devastation of the tank under the "dry" all gasoline will lead to weight problems are not pleasant.

Let us examine how we can pinpoint the exact fuel consumption of a car:

1. At the filling station to refuel the fuel tank full;
2. We write down the odometer reading (the instrument showing the mileage of the car);
3. Exploit the car deck to the red light;
4. Refill vehicle fuel tank to complete;
5. Immediately after refueling, odometer and write poured in second time fuel;
6. We produce fuel calculations.

Calculation of the exact fuel consumption is made in the following sequence:

1. Subtract the first odometer second, it will run the car after the first refueling. Approx. 83209-82827 \u003d 382 km;
2. The next step we divide the reported runs on the amount of fuel poured into the second refueling and get the fuel consumption per 100 km. Approx. 382 / 40.5 \u003d 9.43 l;
3. Up, car consumption is 9.43 / 100 liters / km.

What affects the fuel consumption

Fuel consumption car affects many different factors. For many motorists a secret, for example the air conditioner, headlights, rear seats and the audio system also has an impact on the vehicle fuel consumption.

List the reasons because of which increases the fuel consumption of the car:

• driver's driving manner;
• Riding with no warm up the engine;
• Incorrect operation of the engine control system;
• A fault in the automatic transmission;
• Improper operation of the engine of the injector;
• The quality of the engine oil;
• Included air conditioning or climate control;
• Improper pressure in the fuel system of the engine;
• A clogged air filter;
• Heated seats;
• Heatable windshield and rear window;
• Included lights;
• Wide wheels;
• Low tire pressure;
• Open windows at speeds exceeding 50 km / h (reduced aerodynamic properties of the vehicle);
• Poor-quality fuel;
• An overloaded vehicle;
• Impaired geometry (alignments) wheels;
• Wrong gap in the spark plugs.

and much more…

As can be seen from the above list on fuel consumption affects the mass of various factors.

Ride mode, as affected by fuel consumption

The driving manner of the car owner significantly affects fuel consumption, so, for example, a smooth and uniform movement wins more than 20% of fuel economy than riding with sharp accelerations and braking.
To reduce fuel consumption directly in the automatic transmission, it is not recommended to use the modes "Sport" and "Kickdown", as they significantly increase fuel consumption.
If you have the "Winter" mode, it is recommended to switch to it. It will provide gear shifting, on low engine speed, as a result, the fuel consumption will decrease.

Interesting! The main aspects of the economical driving of the car are: a quick transition to an elevated stage of transmission and riding rolling.

Air conditioning or climate control, how they affect fuel consumption

The conditional effect of the operation of the air conditioner or climate control can be divided into 2 different modes - it is urban and track:

• City mode - in this mode the main part of the time the car engine works at idle. Air conditioning in this mode elementary lack of energy. Therefore, it takes part of the car engine power, as a result, increasing fuel consumption.
• Track mode - directly in this mode, the car engine works with high load. And part of the power selected by air conditioning, little noticeable. In addition, when the air conditioner is turned on as the rules of the car window are constantly closed - this significantly increases the aerodynamic properties and reduces fuel consumption.

Interesting! In urban ride mode, air conditioning included or climate control increase fuel consumption from 5 to 15 percent. Percentage The increase in fuel consumption depends on the power of the car engine. The smaller the power of the engine, the greater the increase in fuel consumption.

Heated seats, how they affect fuel consumption

Heated seats as well as all other electric users increase fuel consumption. This happens due to an increase in the consumption of electricity from the car power grid, as a result, the generator increases the charge given by the direct increase in fuel consumption. The more such electric consumers are included in the car, the stronger the fuel consumption increases.

Over-free car, how it affects fuel consumption

The cause of increased fuel consumption can also be an overview of the car or the use of a trailer device. Consider a Read more:

• Over-free car - fuel consumption, fully loaded car increased by 40 percent. And every 100 kg of cargo increase consumption by 8-10%, depending on the class of the car. This happens due to an increase in the output of the engine power, as the larger the mass of the car, the more power you need for its movement.
• Trailer device - the mid-size trailer increases fuel consumption by 55-60 percent. An increase in consumption occurs for two reasons. The first is the increase in the mass of the car, and the second, the trailer significantly reduces the aerodynamic properties of the vehicle.

So if you downloaded the full car, and the trailer was picked up in the additive, you can safely prepare for increasing flow 2 times.

Tires, how they affect fuel consumption

The size and weight of automotive tires are also capable of providing a significant effect on fuel consumption. So, for example, the large and heavy wheels installed on the passenger car from the SUV with 100% probability will significantly increase fuel consumption.
It should also be said that, as a rule, automatic transmissions are developed to work with a specific type of wheels. So hydraulics and directly electronic gear control system will work efficiently only with a specific type of wheels. Otherwise, it is fraught with an increase in fuel consumption.
Lailed tires also increase fuel consumption. In addition, the incorrect disorder convergence also increases fuel consumption. In detail on adjusting the "Geometry" of the car can be found in "This article".

Interesting! Some modern manufacturers of automatic gearboxes added to the adaptation function. Which changes the box settings under the specified type of wheels, but even this function will not save from increasing the fuel consumption when installing wheels from the SUV on the passenger car.

Economical speed

Depending on the type of engine and the installed gearbox, the maximum speed can change. As a rule, it is in the 50-90 km / h. Excess this speed indicator increases car fuel consumption.

Fuel quality as it affects consumption

The quality of fuel also significantly affects its consumption. And more precisely, the influence is an octane number if it is lower than the fuel consumption increases. So, for example, if 95th gasoline is specified in the instructions for the car, and the car was filled with 92nd, fuel consumption increases.
With poor-quality gasoline, it is allowed to pour a mark to the step above at an octane number - this will reduce fuel consumption, but the higher the octane number of gasoline, the more expensive.

Euro fuel

Euro standard fuel today has 6 generations already. The higher the euro standard, the more fuel consumption and the emission of harmful substances in exhaust gases is reduced. From the beginning of 2016, the Euro-5 standard was relevant for Russia.

Fuel Exposure - Signal of Car breakner

Increased fuel consumption can talk about malfunction in the car. The following malfunctions are carried out to elevated fuel consumption:

• Disrupting the operation of the sensors of the electronic motor control unit. If there are problems with the sensors, the control unit incorrectly calculates the load on the engine, which entails the loss of its power and increasing the fuel consumption;
• Contaminated injectors also very often serve as an increase in fuel consumption. Due to the contamination of the nozzles, there is a poorly spraying of the fuel mixture into the combustion chamber, and in extremely severe cases, it does not occur at all, the fuel is simply fed;
• During the non-replaced air filter also becomes a frequent cause of fuel recalculation;
• A contaminated air filter leads to "air starvation" and incorrect operation of flow meters;
• Old or low-quality engine oil can lead to an increase in fuel consumption by 15-20 percent;
• The breakdown of the catalytic reactor reduces the engine power, and increases the consumption of fuel.

Car maintenance - the path to fuel economy

Timely service, replacement of consumables and cleaning are a guarantor of its long and economical work.
So timely cleaning of the injector and the engine will significantly reduce the costs of both fuel and repair of the car. Details about cleaning the car injector can be found in the article. "Injector cleaner, what cleaner is better", but about the cleaning of the engine in "The engine is focused on how to bring the engine to normal operation.".

Tips of professionals

• To reduce fuel consumption at speeds of more than 50 km / h, the windows should close - it will largely increase the aerodynamic properties of the car;
• Refuel only high-quality fuel on verified gas stations;
• If the quality of gasoline is low, it is possible to refill with a gasoline with an increased octane number, for example, instead of the 92nd pour the 95th;
• The magnificent savings on the fuel is the option of transferring a car for gas, by installing gas-filled equipment;
• To save on a combustion, follow the optimal economic velocity, 80-90 km / h;
• To reduce fuel consumption, set daytime running lights. Middle light lights increase fuel consumption by 5%, and long-range 10%;
• Use a smooth and calm driving technique - it will also significantly increase fuel savings;
• Do not rely and buy all sorts of "miracle" devices offered on the network. Sellers of these devices promise almost a magically to reduce consumption in 2, and even 3 times, in fact, when they are installed, absolutely nothing changes, except that money in his pocket becomes less.
• Do not ride on the 1st transmission, as soon as the car began the movement should immediately switch to the 2nd.

Interesting! There is a stereotype that the automatic transmission significantly increases fuel consumption in comparison with mechanical. So it was really, but every year more and more cars appear with an "machine" which is significantly saving "mechanics".
