DEVICE FOR CONTROLLING THE IDLE R.P.M. FOR INTERNAL COMBUSTION ENGINE

摘要

The idle revolution of an internal combustion engine is controlled by a device which includes an average position deflection operation portion for averaging a position deflection between a predetermined position of an actuator for controlling a throttle value of the engine and an actual position over a predetermined time period to correct the predetermined position with an average value to thereby obtain a desired idle revolution of the engine. By introducing a short time position deflection into the average position deflection, which corresponds to a temporary variation of engine load, an undesired effect of such variation can be removed.
