摘要： A variable valve timing apparatus includes: a variable valve timing mechanism; an intermediate locking mechanism that locks the valve timing at an intermediate timing; and a hydraulic pressure supply device that hydraulically actuates these mechanisms. The hydraulic pressure supply device uses a single oil control valve to control a state where lubricating oil is supplied to or drained from each of an advance chamber, a retard chamber and an intermediate chamber of an intermediate locking mechanism. The oil control valve has first to fourth modes. The oil control valve advances the valve timing and actuates the intermediate locking mechanism in a projecting direction in the third mode, and, under a situation that the amount of lubricating oil supplied to the variable valve timing mechanism is smaller than that in the third mode, advances the valve timing and actuates the intermediate locking mechanism in a release direction in the fourth mode.

摘要： A variable valve timing mechanism changes a relative rotation phase of a camshaft to a target phase based on hydraulic pressure supplied to an advance and a retard sides pressure chambers. A lock mechanism is placed in a locked state in which the relative rotation phase is locked at a maximum retard phase when the hydraulic pressure in the advance and the retard side pressure chambers is low, and that is placed in an unlocked state in which the locked state is released when the hydraulic pressure becomes high. Hydraulic pressure regulations in a first mode that changes the relative rotation phase to a side toward the maximum retard phase and in a second mode that changes the relative rotation phase to a side away from the maximum retard phase are executed in combination during a period from when an operating switch is turned off until a crankshaft stops rotating.
