Control system and control method for in-cylinder injection type internal combustion engine |
摘要 |
It is highly likely that fuel is already adhered to the inside wall surface of the combustion chamber at the beginning of engine startup when it is estimated that the temperature at the beginning of engine stop of the most recent engine operation is low when the engine is restarted. Under these conditions, a fuel injection quantity is reduced or an intake air quantity is increased when the engine is restarted. Therefore, even if the adhered fuel vaporizes when the engine is restarted, the air-fuel ratio will not become excessively rich as a result.
