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.

Claim (Index 9):
A control device of a direct-injection internal combustion engine comprising:\n an evaporated fuel processing device configured to supply fuel vapor generated in a fuel tank as evaporated fuel to the internal combustion engine; and a control unit configured to switch an injection count of a multiple-stage injection according to an operating region and perform the multiple-stage injection, the multiple-stage injection being configured to divide fuel into multiple times in one combustion cycle and inject the fuel, wherein: the operating region is preliminarily divided into a plurality of regions of different injection counts, and the control unit is configured such that, when an injection pulse width of each of the injections falls below a minimum injection pulse width, the control unit narrows an operating region in which the injection count of the multiple-stage injection is large compared with the case of the injection pulse width of each of the injections being equal to or larger than the minimum injection pulse width, through reducing each of the injection counts of the plurality of regions or reducing each size of the plurality of regions.
