Diesel engines

Diesel fuel on DIN EN 590

Tsetanovoye number not less than 49

Do not use biodiesel fuel (methyl air of rapsovy oil)

Tsetanovoye number characterizes ability of diesel fuel to spontaneous ignition.

Operation in winter conditions

winter diesel fuel which depending on its brand provides continuous work of the engine at temperature to - 15°С or to - 22°С.

Heating of the fuel filter

The car is equipped with the device of heating of the fuel filter. Thanks to it - 15°С, it is possible to use the fuel calculated on its application at temperature to at temperature approximately to - 25°С.

If at air temperature below - 25°С fuel became so dense that the engine is not started, let's to the car some time stand in a warmed room enough.

To diesel fuel it is not necessary to mix the various additives increasing its fluidity.

The fuel system consists of a fuel tank, топливопроводов, the filter, the fuel pump and system of injection of fuel.

The fuel tank has two chambers. The tank is located under back seats. The available stock of fuel is shown to the driver on the dashboard. And the fuel stock for each chamber is measured by the separate sensor. The microprocessor in the block of the dashboard counts the current content of fuel on the basis of impulses of injection, speed of movement and electric signals of the lever sensor.

Ventilation of a fuel tank is carried out through the closed system of removal of air. At the petrol engine harmful pairs of gasoline gather in an adsorber and move under control in the engine.

Receptions of economic operation of the car

Essential influence on fuel consumption renders style of driving of the car. Some councils on reasonable operation of the car below are given:

- After engine start at once get under way from a place even if it occurs on a frost.
- At a stop of the car lasting more than 40 with switch off the engine.
- Move always on the highest transfer.
- At movement on big distances whenever possible support uniform speed. Avoid movement on high speeds. Operate the car circumspectly. Without need do not brake.
- Do not transport on the car superfluous cargo. The luggage carrier established on the car, for example, on a roof whenever possible remove.
- Check pressure of air in tires. Do not allow excessive pressure decrease.
