AUTOMOTIVE VEHICLE DUAL-FUEL DIESEL POWER SYSTEM Russian patent published in 2019 - IPC F02M43/00 F02D19/06 F02D19/08 

FIELD: engine building.

SUBSTANCE: invention relates to engine building and can be used in the power supply system of motor vehicle diesel engines. Dual fuel fuel system for diesel engine of automotive equipment contains mineral fuel tank 1, vegetable oil tank 2, mineral fuel filters 3 and vegetable oil 4, fuel filter of fine purification 5, electric pumps for supply of mineral fuel 7 and vegetable oil 8, high-pressure fuel pump 9, nozzles 10 and mixer 11, in the inlet channels of which are installed injection 15, 16 and bypass valves 17, 18 and electric dampers 19, 20, electrically connected to electronic control unit (ECU) 21, three-position electric switch 25, load-speed mode sensor 22 and thermistor 23 arranged in input channel of high-pressure fuel pump 9, tuned to actuation temperature 30±2 °C and electrically connected through electric signal amplifier with electric pump for supply of vegetable oil 8 and ECU 21. Loading mode sensor is a fuel flow meter 29 electrically connected to ECU 21 and hydraulically communicated with mixer 11, while the speed mode sensor functions as one of the phase windings of standard alternator 30 of the automotive vehicle.

EFFECT: automatic control of electric doses of mineral fuel and vegetable oil depending on loading and speed modes of diesel engine operation.
