ABSTRACT:
A fuel injection control device for controlling a synchronous injection time period and an asynchronous injection time period. When the synchronous injection time period calculated from the operating state of the engine exceeds one time period of the synchronous injection, the actual synchronous injection time period is restricted so that it does not exceed one time period of the synchronous injection. When the request for the asynchronous injection occurs during the time the synchronous injection is carried out, the actual synchronous injection time period is prolonged by the asynchronous injection time period.
