When, with a piston assuming the top dead center (TDC) on the compression stroke, a fuel is injected from a nozzle of a fuel injection valve, the injected fuel from the nozzle is guided to reach electrodes of a spark plug by a concave surface defined by a crown portion of a piston. A control unit is provided that controls the fuel injection valve and the spark plug. The control unit is configured to carry out under a given condition controlling the fuel injection valve to start the fuel injection at a time before the top dead center (TDC) on the compression stroke and finish the fuel injection at a time after the top dead center (TDC) on the compression stroke; and controlling the spark plug to carry out the ignition at a time after the top dead center (TDC).
