At fall of external temperature fluidity of diesel fuel owing to paraffin loss decreases. Diesel fuel gets a honey consistence. For this reason in the winter the special additives increasing its fluidity that provides engine start at temperature to - 15°С are entered into fuel and - 22°С (gasoline is worse AI-95).

The specified additives not always are sufficient for steady operation of the engine. Therefore the fuel filter is equipped with electroheating. It provides preservation of properties of fuel even at low external temperature.
