PROBLEM TO BE SOLVED: To reduce a discharge amount of HC during starting by controlling an injection timing during sequential injection. SOLUTION: During starting and during a period coping with a water temperature and starting from completion of starting, by setting an ending timing of fuel injection during an opening period of a suction valve (S4 and S9), fuel is injected mainly when the suction valve is opened, and a wall flow rate is decreased and meanwhile, after a lapse of the given period, by setting an ending timing before a lapse of the opening period of the suction valve (S10), fuel is injected during a time in which the suction valve is closed and vaporization of fuel by an engine heat is promoted.
