  • Patent number: 4520780
    Abstract: A fuel injection pump for a diesel engine includes an input shaft rotated with the crankshaft, and a housing and a plunger which slides in a bore formed in the housing and is coaxial with the input shaft, with a high pressure chamber being defined at an end of the plunger between it and the bore. The plunger rotates with the input shaft and reciprocates so as to pump fuel at high pressure from the high pressure chamber to the engine cylinders, under the control of an electrically actuated electromagnetic valve, comprising a solenoid coil, which selectively vents the high pressure chamber according to the control of a control means, so as to provide fuel injection in appropriate amount to the diesel engine. There is provided a means for determining whether or not the voltage across the solenoid coil of the electromagnetic valve, when supply of power thereto changes from the ON to the OFF condition, rises higher than a certain value, or not.

  • Patent number: 4519353
    Abstract: A fuel injection pump for a diesel engine includes a means for calculating a proper fuel injection amount per each engine stroke and a means for injecting an amount of fuel per each engine stroke approximately equal to this proper fuel injection amount determined by this injection amount calculating means. The pump also includes a means for calculating a reference combustion time which represents approximately how long combustion in an engine stroke should last, and a means for detecting the approximate start and end of combustion in that engine stroke.
