ABSTRACT:
The amount of engine acceleration is detected as the amount of change in the absolute pressure in the intake passage, and an asynchronous fuel injection is conducted regardless of the crank position as the amount of acceleration exceeds a predetermined reference value. In ordinary state of engine operation, the synchronous fuel injection is conducted in synchronism with the crank rotation such that the air-fuel ratio of the mixture coincides with the stoichiometric one, upon sensing the air-fuel ratio from the content of oxygen remaining in the exhaust gas. The mixture is made richer or leaner than the stoichiometric one in accordance with the state of operation of the engine. The judging level for the judgement as to whether the asynchronous fuel injection is necessary or not is increased or decreased in accordance with the air-fuel ratio so that the asynchronous fuel injection is conducted taking into account also the air-fuel ratio.
