INTERNAL COMBUSTION ENGINE FUEL FEED CONTROL DEVICE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; transport engineering; vehicle fuel systems. SUBSTANCE: in device to control fuel delivery into internal combustion engine, control unit has additional series-connected filter 3, frequency divider 4, frequency-to-voltage converter 5, nonlinear voltage generator 11, voltage adder 13, voltage-to-pulse length converter 14 and direct, alternating and nonlinear voltage pickups 8, 9 and 12, respectively. Control unit is coupled with ignition moment and throttle valve angular position pickups 1 and 7, respectively. Output of voltage-to-pulse length converter 14 is connected through output signal amplifier to winding of electromagnetic nozzle 16. EFFECT: improved engine economy both at constant speed and at acceleration. 2 cl, 2 dwg
