DEVICE FOR SUPPLYING PILOT DOSE OF DIESEL FUEL TO INTERNAL COMBUSTION ENGINE WHEN CONVERTING IT INTO GAS-DIESEL Russian patent published in 2023 - IPC F02D19/08 F02D19/10 F02M43/00 F02B69/04 

FIELD: gas-diesel engines.

SUBSTANCE: invention relates to systems for regulating the fuel supply of gas-diesel engines equipped with in-line high-pressure fuel pumps (HPFP) with an all-mode HPFP speed controller. The device contains an all-mode direct-acting centrifugal speed regulator (1), which has the ability to influence the fuel rail (2) of the HPFP (3) through the main lever (4), connected by a working mixture supply element (5), including a control knob (pedal) (6) with an electronic relay (7) that changes the supply of gas fuel by controlling the operation of electromagnetic gas injectors (8) located in the intake manifold 9 of the gas diesel engine. To directly influence the fuel rail (2) of the injection pump, there is a controlled remote electric drive with a control driver, consisting of a stepper motor (10) with a screw mechanism (11), the shaft of which is kinematically connected to a fork (12) and rod (13) articulated with each other by hinges (14), and to the main lever (4) by means of a slider (15) moving in the guide groove (16) of the fork (12).

EFFECT: simplifying the design and increasing the accuracy of the operation of the HPFP in gas-diesel mode while maintaining the power and economic characteristics of the engine, as well as improving the economic and environmental performance of the gas-diesel engine.
