PURPOSE:To reduce the production cost and make easy the feedback control by adjusting the basic injection timing with accuracy on the basis of the rotating speed signal from an engine rotating speed sensor which is built in a fuel injection pump. CONSTITUTION:A micro-computer 13 inputs the information signals from the various sensors, and, according to the result of its arithmetical processing, controls an actuator 24 for the contro of fuel injection timing to maintain the operating state of an ingine 12 in the most suitable condition. A fuel injection pump 11 is equipped with an engine rotating speed sensor 18, the signal from which is arbitrarily advanced or retarded through an adjusting circuit 19 to adjust the basic injection timing with accuracy. In this way, the crank position angle detecting device is made unnecessary, reducing the product cost and making the feedback control easy. |
