To avoid such a phenomenon that the discharge spark of an ignition plug 18 is interrupted as the velocity of fuel sprays from a fuel injection valve 24 is increased to increase the intensity of a current around the fuel sprays.
Fuel is injected from the fuel injection valve 24 so that only one of the spaces where pressure may drop resulting from the plurality of fuel sprays formed by the fuel injected from a plurality of nozzle holes of the fuel injection valve 24 includes a space between a center electrode 18a and a ground electrode 18b of the ignition plug 18. The fuel is injected from the fuel injection valve 24 so that there are different distances between each of two fuel sprays formed to hold the ignition plug 18 therebetween, out of the plurality of fuel sprays, and a center axis L of the ignition plug 18. In this construction, electric energy to be supplied to the ignition plug 18 is set to be varied with the revolving speed of an engine 10, the load of the engine 10, and the fuel injection pressure and time of the fuel injection valve 24.
