CORRECTING DEVICE FOR FUEL INJECTION PUMP OF SUPERCHARGE INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: correcting device has servomotor limiting displacement of fuel meter in fuel injection pump, and two air pressure transmitters which control servomotor by spool pairs. One of transmitters is provided with diaphragm and is in communication with engine intake manifold, and the other is barometric one and is placed in communication with atmosphere. Barometric transmitter in correcting device defines maximum tolerable fuel delivery and, through flexible feedback with diaphragm transmitter, contributes to increase in accuracy of control of power characteristics and fuel economy of vehicles operating on rough terrains. EFFECT: enlarged operating capabilities. 2 cl, 2 dwg
