Operation in the winter
At decrease in temperature of external air the fluidity of diesel fuel owing to paraffin loss decreases. Diesel fuel on the fluidity becomes similar to honey and can hammer the filter. For this reason the additives increasing the fluidity of fuel and providing a possibility of start of the engine at a temperature of external air to – 22 °C can be entered into diesel fuel in the winter. To exclude clogging of the fuel filter at a low external temperature, fuel goes to the heat exchanger.
