DUAL-FUEL DIESEL POWER SYSTEM WITH MICROPROCESSOR-CONTROLLED ELECTRIC METERS OF BIO-OIL FUEL COMPONENTS Russian patent published in 2024 - IPC F02M43/00 F02D19/08 

FIELD: engine building.

SUBSTANCE: used in the power supply system for diesel engines of automotive vehicles. A dual-fuel diesel power system with microprocessor control of electric meters for bio-oil fuel components contains a petroleum diesel fuel tank (1), a vegetable oil tank (2), intake lines for petroleum diesel fuel (3) and vegetable oil (5), coarse filters (4, 6) , mixer (7), having two input channels (8, 9) with electric meters of petroleum diesel fuel (10) and vegetable oil (11) installed in them, and one output channel (12), microprocessor (13) for controlling electric meters (10) and (11), load sensor (14), bio-oil fuel supply line (15), containing a fuel priming pump (16), a fine filter (17), a high-pressure fuel pump (18) with a fuel supply control rail (19) and injectors (20). The petroleum diesel fuel tank (1) is located 100-120 mm above the vegetable oil tank (2). Electric meters (10) and (11) are electrically connected through a microprocessor (13) to a thermistor ambient temperature sensor (21) mounted on the outer surface of the bottom of the tank (2), and a ring-shaped inductive load sensor (14), in which the rack (19) performs the functions of a solenoid (22) screwed into its end.

EFFECT: ensuring the required percentage of petroleum and biological components in bio-oil fuel when preparing it in a mixer, depending on the ambient temperature and the load mode of the diesel engine.
