DUAL-FUEL SYSTEM OF A VEHICLE WITH CONTROLLED HEATING OF VEGETABLE OIL Russian patent published in 2019 - IPC F02D19/06 F02M43/00 F02M31/125 

FIELD: engine building.

SUBSTANCE: invention relates to propulsion engineering and can be used in transport piston diesels. Dual-fuel power supply system of vehicle diesel engine with controlled heating of vegetable oil contains mineral fuel tank 1, vegetable oil tank 2, mineral fuel and vegetable oil mixer 3, fuel supply line 4 including coarse filter 5, fine filter 6 and fuel feed pump 7, excess fuel drain line 8, high-pressure fuel pump 9 with excess fuel drain valve 10, nozzles 11, bypass valves 12 of mineral fuel and vegetable oil, vehicle on-board network current source 13, electronic control unit 14, vegetable oil temperature sensor 16, electric heater-posistor 15 arranged in vegetable oil tank 2 and having at least two vegetable oil heating channels 22, 23. Main circuit channel 22 is connected to electric circuit of electric heater by signals of vegetable oil temperature sensor 16, and the electric circuit of the electric heater of additional channel 23 is automatically connected by means of electromagnetic relay 24 electrically connected to the fuel flow sensor 17.

EFFECT: electric energy saving of vehicle on-board network and automation of vegetal component (oil) of fuel mixture electric heating due to automatic change of electric heater power depending on consumption of mixed fuel at diesel engine operation at various load-speed modes.
