PROBLEM TO BE SOLVED: To improve torque by suppressing generation of knocking, in a low rotation and high load region. SOLUTION: In an operating region in which low rotation and a high load are generated, a fuel injection amount is set so as to generate a mixture of stoic or rich as a total unit in a combustion chamber. In the case of injecting the set fuel injection amount, dividing it into during an intake stroke and during compression stroke, most part of fuel is injected during the intake stroke.
