    摘要: A control apparatus for a direct injection type engine is provided for reducing an amount of fuel that adheres to and that remains on a crown surface of a piston 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. 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.

    摘要: There is provided a fuel injection control apparatus for an in-cylinder injection internal combustion engine that limits increases in the amount of discharged PMs and the amount of oil dilution when a demanded amount of injection is changed while divisional injection is being performed. The control apparatus is provided for an internal combustion engine having a fuel injection valve for injecting fuel into a combustion chamber of the internal combustion engine, a fuel pump for feeding fuel to the fuel injection valve by pressuring the fuel, and a fuel storage chamber storing fuel to be supplied to the fuel injection valve. In the engine, divisional injection control including a plurality of fuel injections executed in one cycle is performed. When a demand for making a change in the amount of fuel supplied per cycle occurs, changes in the amount of fuel injection are made according to injection times.
