ABSTRACT:
An engine control system is disclosed which comprises a means for storing engine control data with such parameters as throttle valve opening angle for regulating the quantity of the air taken into an engine cylinder, an intake manifold depression and an engine speed, a means for reading-out said engine control data with the parameters of the intake manifold depression and the engine speed in light load condition and with the parameters of the throttle valve opening angle and the engine speed in heavy load condition, and a means for controlling the engine using the read-out data. The change of parameter in said system is achieved by using at least one of the throttle valve opening angle, intake manifold depression, engine speed and the engine control data. The locus or the valve of the changing point in parameter replacement from the intake manifold depression to the throttle valve opening angle, or vice versa, may have a hysteresis characteristic. Furthermore, said changing point may be shifted in response to the engine speed.
