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.

摘要： Provided is a control device for an in-cylinder injection engine 1 which reduces an amount of fuel attaching and remaining on a piston crown surface so as to bring the first injection as advanced as possible and suppress an increase in the number of exhaust particles of PM, when fuel injection is performed a plurality of times in one cycle in the in-cylinder injection engine 1. At least the first fuel injection of the respective injections dividedly performed the plurality of times is performed in an intake stroke. At least the first injection start timing IT1 of the respective injections dividedly performed the plurality of times is set in accordance with an EGR amount. The first injection start timing IT1 is more advanced when the EGR amount is large than when the EGR amount is small.
