Power supply system and release

Specifications

Separate characteristics are provided also in the text of the Head and in case of obligation of their performance are highlighted in bold type

Fuel

Petrol engines

Unleaded gasoline is not worse than AI-95 (engines with the catalytic converter).
Unleaded or ethylated gasoline is not worse than AI-95 (engines without catalytic converter).
Use of gasoline not worse than AI-91 is allowed, at the same time engine capacity is cut and fuel consumption increases.

Diesel engines

Automobile (not ship or boiler) summer or winter diesel fuel with the content of sulfur is not higher than of 0.5%. Do not apply biodiesel fuel and methyl air of rape oil.

Preliminary heating of fuel in the filter prevents jelling of fuel during the movement of the car.

Do not apply special means to reduction of viscosity of fuel.

At temperature drop of external air below -9 °C to summer diesel fuel add kerosene (to of % of total volume)

From-9 to -15 °C

10%

From-15 to -25 °C

30%

It is below -25 °C

50%

At temperature drop of external air below -20 °C to winter diesel fuel add means of reduction of viscosity or kerosene (to of % of total volume)

From-20 to -26 °C

10%

From-26 to -31 °C

30%

It is below -31 °C

50%

As the exception is allowed addition to of 30% of low-octane gasoline (unleaded for cars with the catalytic converter) to diesel fuel.
