According to the definition from the dictionary mode of the device when no load is called idle. For car mode the engine is idling indicates that the vehicle is at a standstill, but the engine is running. For example, when boarding and disembarking passengers. Of course, running engine consumes fuel. And what will be the fuel consumption at idle?

The engine always starts in idle mode (idle). This mode allows you to assess the quality of the motor. The main criterion for evaluation will be the fuel consumption at idle. In this mode, obtained from the combustion of fuel energy is spent just on the motor.

I Must admit that to estimate the fuel consumption of cars, the task is quite complicated. There are too many factors influencing this action. For example, what type of engine? Carbureted or fuel injected? For different engines the fuel consumption and the factors that influence it, will be different.

On the question of how to calculate fuel consumption, it may be advisable to use either of the two practices. In the first case, you have to drive until the fuel tank is completely empty, whereupon the machine stops. Then pour a known quantity of gasoline, for example, Jerry cans of 10 litres to pour into the tank. To ride the amount of fuel needed while the engine does not stall again. And then, dividing 10 liters traveled the number of miles, get the value.

According to another method should pour fuel into the tank via the tube and drive as much as possible after filling, given the distance covered. Then pour from the measuring cups, for example, cans of gasoline to the same level that was in the beginning of the trip, i.e. before the tube. To find out how many liters of fuel had to be topped up. Here is the number, which had to be refilled, should be divided into the kilometers traveled - will the consumption of gasoline.

Oil consumption in the engine. Six reasons

It is Hardly possible to find a motorist who would not be worried about the increased oil consumption. It is especially annoying when it happens with another new motor. Here are the most common causes that result in the consumption of oil in the engi...

However, it is necessary to properly evaluate the results. In many ways, they affect not only the engine but also the various related effects. So if the car is new, motor it neprorabotanny and on the first ten thousand kilometers it will be tested. Engine details of the car will get used to each other, and to consume fuel, the motor will be more. This is normal and you have nothing to worry about.

The Condition of the road surface also affects fuel consumption. When driving on dry asphalt it will be one value, when driving on fresh snow it will be much more.

Therefore, the rating of motor is best carried out when working at idle. If the revs H. H. more than 1,000, it indicates any faults or malfunctions in the car. You need to find and rectify the defect or to carry out the adjustment of the engine. Another indicator to assess the operation of the engine will be fuel consumption at idle.

To Define such flow is very difficult, because there is nothing to compare. Appreciate it into practice, usually in litres per hour; for «Lada» the value obtained practically is around one liter per hour.

The best way to assess fuel consumption at idle and work the motor, as mentioned above, according to the idle speed. Albeit indirectly, but objectively. On a normally running engine and good nodes and sensors of the machine should be 800-1000 rpm. Deviations from this value would indicate a fault in the vehicle.

In the presented paper describes the operation mode without loading of the engine. Identifies and describes the mode of operation, called idle. The definition and measurement methods of fuel consumption in normal driving mode, and in idle mode.
