PROBLEM TO BE SOLVED: To accurately control the fuel injection amount at the starting time of an engine. SOLUTION: ECU 30 calculates the starting time fuel amount according to the engine water temperature, in the process from the first explosion to the final explosion of an engine 10, and at the same time, it corrects the starting time fuel amount to the increasing side, as the engine rotation frequency is the lower. And, in such a fuel amount correction, the correcting amount (the rotation correcting coefficient) is increased or decreased according to the increasing degree of the engine rotation frequency at each time. Actually, the rotation correcting coefficient is increased or decreased according to the water temperature. Consequently, even though in the case engine friction becomes larger at the engine starting time in a very low temperature, for example, when the engine rotation frequency increasing level at the engine starting time is charged, the required fuel amount according to the friction can be injected and fed, so as to obtain a desired output torque constantly. |
