Abstract
An engine control system and an engine control method are disclosed wherein a combustible component quantity of intake air, reflecting combustible components in a crankcase of an engine, is calculated on the basis of a deviation between basic injection quantity for a target rotational speed to be attained and an actual injection quantity during operation to perform idling stabilizing control. A ratio of the combustible components mixed to engine oil is calculated on the basis of the combustible component quantity of intake air and a temperature of engine oil. During a status of the engine with a given temperature of engine oil and the mixing ratio of the combustible components in engine oil, a fuel injection affect eliminating operation is executed.
