PROBLEM TO BE SOLVED: To prevent occurrence of abnormal combustion in an internal combustion engine performing quick start at high temperature. SOLUTION: It is determined whether or not a stop position of a piston in start of an internal combustion engine in each cylinder is in a period T2 after the start of an intake period Ts and before an approximately 90°ATDC of an intake TDC. Further, it is determined whether or not a cylinder temperature of a cylinder of which the stop position of the piston is in the period T2 is higher than a specified value, from an atmospheric temperature, an engine water temperature, and an elapsed time from the stop of the internal combustion engine until a restart condition is satisfied. When the stop position of the piston is in the period T2 and if it is estimated that the cylinder temperature is higher than the specific value, the fuel is injected in a plurality of times in a fuel injection period F2 in the period T2, in cranking.
