To provide a control apparatus of an internal combustion engine that reduces particulates in exhaust gas and satisfies both low-fuel consumption and low emission, in an internal combustion engine controlling an intake valve to be retarded.
The control apparatus performs the retard control of the intake valve and controls an injection condition so as to allow a port injection valve for performing intake asynchronous injection and intake synchronous injection into an intake port to change an intake asynchronous injection ratio. The apparatus includes: a separately-injection controller for performing the asynchronous injection of the port injection valve during an intake asynchronous injection period Taup1 in which the asynchronous injection ends further on an exhaust top dead center (TDC) side than an intake-valve opening period tp3 and for performing the injection of an uninjected remaining amount during an intake synchronous injection period Taup2 which starts from the intake-valve opening period tp3, the injection of the uninjected remaining amount exceeding an injection quantity during the intake asynchronous injection period Taup1 by the port injection valve in a required injection quantity; and a separately-injection injection-quantity setting device for each setting the injection quantity during the intake asynchronous injection period Taup1 and the uninjected remaining amount according to a temperature of the internal combustion engine.
