The device of heating of the fuel filter

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 raising its fluidity that provides engine start at temperature to - 15С are entered into fuel and - 22С (gasoline is worse АИ-95).

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