ABSTRACT:
A control system for an internal combustion engine corrects an amount of supply fuel to the engine based upon operating conditions of the engine as well as an estimated amount of adherent fuel adhering to the inner surface of the intake passage and an estimated amount of fuel carried off fuel adhering to the intake passage inner surface and carried into combustion chambers. The correction of the supply fuel amount is limited when the engine is operating in an idling condition. According to a further aspect of the invention, the adherent fuel amount and the carried-off fuel amount are corrected based upon a calculated amount of exhaust gases and a detected operating mode or valve timing of at least one of intake valves and exhaust valves.
