THERMOCOMPENSATION FUEL SYSTEM OF DIESEL ENGINE Russian patent published in 2001 - IPC

FIELD: engine manufacture. SUBSTANCE: thermocompensation fuel system of Diesel engine includes tank, booster pump, filter, pipe-lines, high-pressure fuel pump, transducer- temperature-sensitive resistor mounted at inlet to high-pressure fuel pump, line for discharge of surplus fuel and controllable electromagnetic actuating mechanism electrically connected through amplifier to temperature-sensitive resistor and power supply source. Speed regulator is fitted with direct corrector of fuel supply placed in cylindrical case screwed into case of regulator from outside. Speed master unit is capable of movement in range from maximum fuel supply to its complete cut off, position pickup is kinematically coupled to speed master unit and is electrically connected to amplifier. System also has switch and rack-and-gear drive which rack is mechanically coupled to controllable electromagnetic actuating mechanism mounted for reciprocating motion along guide installed on high-pressure fuel pump from outside. Gear of drive is made fast to case of corrector for automatic turn of the latter through angle proportional to value of signal picked off from transducer-temperature- sensitive resistor. EFFECT: increased accuracy and expanded range of correction of fuel supply depending on change of temperature of fuel. 1 dwg
