DIESEL FUEL SUPPLY SYSTEM FOR AUTOMOTIVE VEHICLE TO OPERATE ON PETROLEUM AND BIO-OIL FUELS Russian patent published in 2024 - IPC F02M43/00 F02D19/06 

FIELD: engine building.

SUBSTANCE: invention can be used in the power supply system for diesel engines of automotive vehicles. The diesel fuel supply system of an automotive vehicle for operating on petroleum and bio-oil fuels comprises an petroleum diesel fuel tank (1), a bio-oil fuel tank (2), oil and bio-oil fuel intake lines (3 and 4), a coarse and fine fuel filter (5 and 6 ), fuel priming pump (7), high pressure fuel pump (8), injectors (9), excess fuel drain line (10), electromagnetic switch (11) for the type of motor fuel, the actuator (12) of which is located at the connection point between the intake lines oil and bio-oil fuels (3 and 4), and its inputs (13, 14) are hydraulically connected to the oil and bio-oil fuel intake lines (3 and 4), and the output (15) is connected to the coarse fuel filter (5). The electromagnetic switch (11) is electrically connected to the power source through a key switch (16) located in the cabin of the vehicle. The actuator (12) is a two-position distributor with a valve shut-off and control element. The drain line for excess fuel (10) from the high-pressure fuel pump (8) and injectors (9) is hydraulically connected to the bio-oil fuel tank (1) at the beginning of its intake line (4).

EFFECT: remote control of an electromagnetic switch for the type of motor fuel, improvement of fuel supply parameters, power and fuel-economic indicators of a diesel engine when operating on bio-oil fuel.
