FIELD: engine building.
SUBSTANCE: invention relates to power supply systems of internal combustion engine, vehicles operating on two fuels. Automotive and diesel fuel supply system comprises fuel tank, fuel coarse filter, low pressure fuel pump, fine fuel filter, high pressure fuel pump, nozzle and fuel lines, fuel heater with main heat exchanger, which operates from waste gas heat energy, installed on engine exhaust system, fuel heating switch, control unit, exhaust gas supply volume changeover and fuel heating shutdown, exhaust gas flow rate control, electromagnetic valves, exhaust gas temperature and fuel temperature sensors. System is equipped with additional temperature sensor located on fuel tank, fuel heater is equipped with additional heat exchanger included into additional closed circuit, which connects it with circulation pump and fuel tank.
EFFECT: reduced load on elements of fuel system, protection of engine against unfavorable effect of high-viscosity biodiesel fuel.
