Abstract
In a predetermined operating region, a fuel injection valve executes a second injection to inject fuel into a cylinder in a compression stroke, and a first injection to inject fuel into the cylinderin the compression stroke or an intake stroke before the second injection. When a purge is executed, the total quantity of fuel to be injected by the fuel injection valve into the cylinder is reduced more than when the purge is not executed, and a fuel reduction quantity of the second injection is made smaller than a fuel reduction quantity of the first injection.
