Abstract
A control system for an internal combustion engine estimates an amount of adherent fuel adhering to the inner surface of the intake passage, as well as an amount of carried-off fuel evaporated form fuel adhering to the inner surface of the intake passage and carried into combustion chambers, determines an amount of supply fuel to be supplied to the engine, based upon operating conditions of the engine, the estimated adherent fuel amount, and the estimated carried-off fuel amount, and supplies the determined supply fuel amount into the intake passage. The control system calculates an amount of exhaust gases to be recirculated from the exhaust passage to the intake passage, and corrects the estimated adherent fuel amount and the estimated carried-off fuel amount, based upon the calculated exhaust gas recirculating amount, based upon the calculated exhaust gas recirculating amount. Advantageously, the exhaust gas recirculating amount is calculated based upon dynamic characteristics of an exhaust gas recirculation control valve and those of exhaust gases being recirculated.
