Abstract
PURPOSE: To prevent the generation of hunting and nocking of rotation by controlling the disorder of fuel feed being produced in a thransitional stage at lower speed and less load in the fuel injection device by which fuel is intermittently fed synchronously with the rotation.
CONSTITUTION: Outputs of the rotation sensor 6 with electromagnetic pickups 64W66, which produce induced electromotive forces by cooperating with the magnetic substances 61W63 that turn once evry twice rotation of the crankshaft, air quantity sensor 2, water temperature sensor 18 and suction air temeprature sensor 19 are fed to the microcomputer 5, the fuel quantity at one time is computed according to the respective input signals to control the fuel injection valve 10. When the rotation change rate obtained by dividing the change of rotation speed by the rotation speed is greater than a previously fixed value, the rotation speed signal used for computing the fuel quantity at one time is corrected. In this way, the fuel feed can be controlled.
