ABSTRACT:
A fuel injection controller of an in-cylinder injection engine determines that a combustion state has deteriorated and executes a split injection for injecting fuel in split amounts into each cylinder in multiple injection events in a cycle of the cylinder if it is determined that a combustion fluctuation is greater than a predetermined determination value during operation of the engine. The fuel injection controller increases a ratio of an injection amount of the first injection event in the split injection and lengthens an injection interval between the injection events as the combustion fluctuation increases. Thus, a wet amount of the injected fuel is reduced to expedite atomization of the injected fuel and to homogenize an in-cylinder mixture gas. As a result, the combustion state is improved.
