ABSTRACT:
A system for controlling no load operation of an internal combustion engine is provided wherein an actual engine speed signal and a target engine speed signal are compared and the air flow past a throttle valve is controlled to reduce the difference between these two signals. Subsequently, an actual air fuel ratio and a target air fuel ratio are compared and the air fuel ratio of the mixture to the engine is controlled to reduce the difference between the actual and target air fuel ratio signals. During deceleration of the engine, air flow is controlled to maintain the manifold vacuum smaller than a predetermined value so as to prevent unnecessary enrichment of the mixture due to the vacuum and then air fuel ratio is controlled to reduce the difference between the actual air fuel ratio signal and a target deceleration air fuel ratio signal.
