AUTO TRACTOR DIESEL ENGINE DUAL FUEL SUPPLY SYSTEM Russian patent published in 2019 - IPC F02M43/00 F02M27/08 B01F11/02 F02D19/08 

FIELD: internal combustion engines.

SUBSTANCE: invention can be used in the internal combustion engines fuel supply systems. Proposed is the dual-fuel power supply system for the car-and-tractor diesel engine, containing the mineral fuel tank 1, the vegetable oil tank 2, the mineral fuel intake line 3 and vegetable oil intake line 4, first-stage fuel filter 5, final fuel filter 6, primary fuel pump 7, high pressure fuel pump 8 and nozzles 9. In the mineral fuel and vegetable oil intake lines communication point to each other a cone-cylindrical body 10 with two inlet 11, 12 and outlet 13 channels is located, in which internal cavity the ultrasonic oscillations piezo emitter 14 is placed, electrically connected to the high-frequency oscillations generation unit 15, powered by the direct current of 12 V from the car-and-tractor vehicle on-board power network. In the body inner cavity a conical resonator chamber 16 is formed, which larger base is in communication with the mineral fuel 1 and vegetable oil tank 2.

EFFECT: technical result: the practical possibility of the high-frequency oscillations energy accumulating and increasing in the body cavity, in which the ultrasonic oscillations emitter is located.
