Abstract
A direct-injection internal combustion engine is controlled such that an injection count of multiple-stage injection is switched according to an operating region, and the multiple-stage injection is performed. The multiple-stage injection divides fuel into multiple times in one combustion cycle, and injects the fuel. Fuel vapor generated in a fuel tank as evaporated fuel is supplied to the internal combustion engine. An operating region in which the injection count of the multiple-stage injection is large is controlled to be narrower when an amount of the evaporated fuel supplied to the internal combustion engine is large, compared with a case of the amount of the evaporated fuel being not large.
