Power supply system and release

Specifications

Separate characteristics are provided also in the text of Head and in case of obligation of their performance are allocated with a bold print

Fuel

Petrol engines

Unleaded gasoline is not worse AI-95 (engines with the catalytic converter).
Unleaded or etilirovanny gasoline is not worse AI-95 (engines without the catalytic converter).
Application of gasoline not worse AI-91 is allowed, thus engine capacity decreases 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 0.5 %. Do not apply biodiesel fuel and methyl air of rapsovy oil.

The preliminary heating of fuel in the filter prevents zagustevany fuels during car movement.

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

At temperature drop of external air is lower - 9°С to summer diesel fuel add kerosene (in % from total volume)

From-9 to - 15°С

10 %

From-15 to - 25°С

30 %

Below - 25°С

50 %

At temperature drop of external air is lower - 20°С to winter diesel fuel add means of reduction of viscosity or kerosene (in % from total volume)

From-20 to - 26°С

10 %

From-26 to - 31°С

30 %

Below - 31°С

50 %

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