DUAL-FUEL SUPPLY SYSTEM OF AUTOMOTIVE DIESEL ENGINE WITH COMBINED CONTROL OF MIXED FUEL SUPPLY Russian patent published in 2024 - IPC F02M43/00 F02D19/06 F02D19/08 

FIELD: engine building.

SUBSTANCE: proposed dual-fuel supply system of automotive diesel engine with combined control of mixed fuel supply comprises mineral fuel tank (2) and vegetable oil tank (1), electric pump (5), fuel mixer (9), in inlet channels (10, 11) of which there are throttle valves (12, 13) with control levers (23, 24) fixed on their axes (14, 15), which are kinematically connected to rotary double-arm lever (28), by means of which the operator can manually set the required volume ratio of vegetable and mineral components of the mixed fuel or, if necessary, switch the operation of the diesel engine to mineral fuel. For automatic control of supply of mixed fuel with different ratio of vegetable and mineral components in inlet channels (10, 11) of mixer (9) in front of throttle valves (12, 13) there are T-pieces (32, 33), mineral fuel (34) and vegetable oil (35) electric batchers are screwed into the outlets of the latter, electric batchers are electrically connected through electronic control unit (36) to sensors of position of rack of fuel pump of high pressure (37), speed of crankshaft of diesel engine (38) and temperature of vegetable oil (39), wherein electronic control unit (36) and electric pump (5) are connected to DC source (41) through switch (4).

EFFECT: expansion of functionality for controlling the dual-fuel supply system of an automotive diesel engine.
