Abstract:
A control apparatus for an internal combustion engine, wherein the internal combustion engine includes a fuel injection valve injecting fuel directly into a cylinder. The control apparatus includes an ECU. The ECU is configured to execute a divided injection control to inject fuel from the fuel injection valve by a plurality of partial lift injections. The ECU is configured to execute a division number reduction control when the value of a spray shape parameter representing spray shape fluctuation is greater than a division number reduction determination value. The division number reduction control is control to reduce the number of partial lift injections in one engine cycle and to lengthen an injection time of each of the partial lift injections.
