Document Type and Number:
Japanese Patent JPH056026
Kind Code:
B2
Abstract:
PURPOSE:To reduce cost by performing feedback correction such that the basic injection quantity corresponding to rotation and load of Diesel engine will provide firing interval corresponding to rotary speed and load thereby eliminating water temperature sensor, suction sensor etc. CONSTITUTION:Fuel injection control of Diesel engine is performed such that the plunger 222 is moved through duty ratio control of spill control solenoid 220 in fuel injection pump 20 to move a spill ring 218. The spill control solenoid 220 is controlled by a control circuit 30 provided with detected levels from flare sensor 1, accelerator opening sensor 32 and upper dead center sensor 104. The control circuit 30 will operate basic injection quantity corresponding to rotary speed and load and to feedback correct the basic injection quantity such that the firing interval to be provided from the flare sensor 1 through an optical fiber 3 will be necessary firing interval operated in accordance with the rotary speed and load.
