Abstract
A fuel injection valve () is configured such that the effective opening area of an injection port () increases as its lift amount increases. A fuel injection control unit (an engine control unit) injects fuel in a lift amount changing mode wherein, when fuel is injected into a combustion chamber () in the terminal period of the compression stroke, the lift amount of the fuel injection valve is set to a predetermined large lift amount in the earlier period of the injection period, and in the later period of the injection period following the earlier period of the injection period, the lift amount is set to a small lift amount smaller than the large lift amount and is in a range where the fuel injection speed increases.
