Filed: 1985-03-19
Abstract: PURPOSE:To both reduce vibration of an engine and improve its fuel consumption, by providing a feedback control loop which controls a quantity of fuel for each cylinder so that an instantaneous speed of each cylinder may become equal. CONSTITUTION:An instantaneous speed of an Diesel engine 3 is detected by a speed detecting part 8 on the basis of the explosion timing by a needle valve lift pulse signal NLP1 in every cylinder from a timing detecting part 10. A control signal is output from the first PID arithmetic part 14 so that said instantaneous speed may be an idle speed and a target speed Nt in a mean value arithmetic part 11. While a difference Dd from a reference instantaneous speed Dr in every cylinder is obtained by a speed difference arithmetic part 24, and the third PID arithmetic part 26 outputs a control signal Do, so that the difference may become O, to be added to the control signal from the arithmetic part 14. And the second PID arithmetic part 20, while receiving a feedback signal from a position sensor 18, controls a quantity of fuel. In this way, a control device, reducing vibration of the engine and enabling also its idle speed to be decreased, promotes the improvement of fuel consumption.
