Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce fuel consumption by enlarging a stratified combustive area, by increasing air intake by an intake increasing means when the necessary fuel amount determined on the basis of at least the engine operating condition exceeds a specific amount, for the stratified combustion which realizes the leans burn with low fuel consumption. SOLUTION: When an amount of fuel injection from a fuel injection valve 1e is smaller than a specific amount, the injected fuel is completely vaporized, and an air-fuel mixture of high ignitability, comprising the vaporized fuel and the intake, is formed near an ignition plug 1a at an ignition time, whereby the stratified combustion of low fuel consumption is performed. But when the fuel injection amount exceed the specific amount, the air intake amount per unit fuel is reduced, and the injected fuel can not get sufficient heat from the intake, so that the supercharging is executed by a turbocharger 4 to increase the intake amount corresponding to an amount exceeding the specific amount.  Whereby the intake amount per unit fuel can be kept in the same condition as the time when the fuel injection amount is equal to the specific amount, and the injected fuel can be vaporized in a short time.
