Abstract
An apparatus and a method for controlling an internal combustion engine are disclosed, wherein upon deceleration of the engine, fuel injection is interrupted on the basis of determination of an engine operating condition to interrupt the fuel injection, while the fuel injection is then restored on the basis of determination of an engine operating condition to restore the fuel injection. When the determination is made such that the fuel injection is to be restored, the ignition timing determined in dependence on the prevailing engine operating condition is delayed. The delayed ignition timing is progressively advanced after restoration of the fuel injection to regain the original ignition timing determined in dependence on the prevailing engine operating condition.
