Abstract:
A valve timing control apparatus includes a housing that is rotatable with a crankshaft; a vane rotor that is rotatable with a camshaft; and a phase controller to compulsorily change a rotation phase of the vane rotor alternately between an advance side and a retard side with respect to the housing if an engine shifts to a high rotation state after the engine continuously has a low rotation state for a predetermined period or more. The engine in the low rotation state has a rotation speed lower than a predetermined rotation speed. The engine in the high rotation state has a rotation speed equal to or higher than the predetermined rotation speed.
