    摘要： A control apparatus for a direct injection type engine 1 is provided for reducing an amount of fuel that adheres to and that remains on a crown surface of a piston 207a so as to suppress the increase of Number of particles as well as advancing the first injection as much as possible when plural fuel injections are carried out in one cycle in the direct injection type engine 1. The first injection timing is set based on a pulse width of at least the first injection among each of injections split plural times, and when the pulse width of the split first injection is short, the injection timing of the first injection is more advanced as compared with a case of a longer pulse width of the split first injection.
