DIESEL FEED SYSTEM WITH TWO-PHASE MIXTURE FORMATION Russian patent published in 2024 - IPC F02D19/08 F02D19/12 F02D41/00 F02M43/00 

FIELD: engines.

SUBSTANCE: invention can be used in fuel supply systems of internal combustion engines (ICE). Disclosed is a diesel engine supply system, comprising a mechanical engine fuel supply system (1) with high-pressure fuel pump (HPFP) (7) with drive gear (8) placed under aluminium cover (9) and hydraulic injectors (10), as well as an electronic system for distributed supply of hydrocarbon activator (11), including electric pump (15), electronic control unit (17) connected to power supply (16), sensors of load mode, crankshaft rotation speed and activator injection moment (18, 19, 20), ramp (21) with pressure regulator (22) and electromagnetic injectors (23) for activator injection into inlet pipeline (25). Functions of the crankshaft speed sensor (19) and the activator injection moment sensor (20) are performed by the electric signal converter (26) containing the Hall sensor chip (27) installed on cover (9) surface, and neodymium magnet (28) fixed on side surface of drive gear (8) of high-pressure fuel pump.

EFFECT: possibility of obtaining information from sensors of crankshaft rotation frequency and moment of activator injection in the form of a single electric signal and reduction of labour intensity for installation of sensors.
