Abstract
PURPOSE: To obtain secures safe engine control by a method wherein R.P.M. of the engine is compared with the R.P.M. set up by the engine running state and if the value resulted from the comparison exceeds a predetermined value and said state continues for a set period of time, the engine R.P.M. control operation is discontinued.
CONSTITUTION: The R.P.M. of an engine 5 is detected at an engine R.P.M. detector 6, the detected output is supplied to a set-up circuit 7 of the engine R.P.M., where the applied value is compared with the reference value which is set-up based on the engine running state. The signal resulted from the comparison is inputted to a R.P.M. operator 8, and if the inputted signal value exceeds the reference value and the excessive value continues for a certain duration predetermined, then an actuator 9 stops the control of R.P.M. While the R.P.M. control is discontinued, A/F operator 3 and A/F actuator 4 make actions to vary the air-to-oil ratio to thinner side thereof. In such a way, even if the R.P.M. actuator 9 causes trouble, a safe engine control can be assured for operation.
