Control device for in-cylinder fuel injection type internal combustion engine
Abstract:
Provided is a control device for an in-cylinder injection engine 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. 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 of the respective injections dividedly performed the plurality of times is set in accordance with an EGR amount. The first injection start timing is more advanced when the EGR amount is large than when the EGR amount is small.
