Abstract:
An engine intake valve timing control apparatus includes a fuel injection control section, a valve open timing control section, and a valve timing change rate setting section. The fuel injection control section is configured to control a fuel injection quantity of fuel injected from a fuel injector into an intake port of an engine in accordance with an operating condition of the engine. The valve open timing control section is configured to control an open timing of an intake valve to a target open timing. The valve timing change rate setting section sets a change rate at which the open timing of the intake valve is changed from a current open timing to the target open timing when the target open timing is updated, the change rate being set using a parameter relating to a vaporization rate of the fuel adhered to the intake port.
