PROBLEM TO BE SOLVED: To achieve favorable startability of an engine during cold start.SOLUTION: If start beginning time battery temperature Tbst is a threshold value Tbref or more during cold start when the engine is started while start beginning time cooling water temperature Twst is lower than a threshold value Twref, correction rotation speed Naj of a value 200 is added to predetermined rotation speed Nset and the resultant is set as threshold value rotation speed Nref (S160, S170), and when engine rotation speed Ne is lower than the threshold value rotation speed Nref, a start time injection amount T0 is corrected by adding a correction amount Ta thereto to set a fuel injection amount T (S190). Thereby, the engine rotation speed Ne is prevented from becoming the threshold value rotation speed Nref or more during initial fuel injection due to high start beginning time battery temperature Tbst to secure increasing correction of a fuel injection amount at the initial fuel injection, and explosion can be produced for the initial fuel injection. Consequently, the favorable startability of the engine can be achieved. |
