Abstract
An object of the invention is to reduce an HC generated in a so-called fast idle period in which an engine and a catalyst are warmed up, stabilize a combustion and achieve an early activation of the catalyst, at a cold starting time of a cylinder injection type engine. In a control apparatus controlling a cylinder injection type internal combustion engine directly feeding a fuel into a combustion chamber by a fuel injection apparatus attached to a portion near an intake valve, the control apparatus controls the fuel injection apparatus so as to carry out an intake stroke injection, makes a lift amount of an intake valve smaller than a lift amount at a time of a high load, and controls such that an opening timing of the intake valve comes closer to an intake stroke side near an intake top dead center, in a fast idle period of the cylinder injection type internal combustion engine.
