Abstract
A valve timing controller includes a lock mechanism that locks a rotation phase at a main lock phase when an internal combustion engine is started with an ambient temperature more than or equal to a preset temperature. The main lock phase represents a rotation phase set for closing an intake valve at a later timing later than a timing when a piston reaches a bottom dead center of a cylinder in the internal combustion engine. The lock mechanism locks the rotation phase at a sub lock phase representing a rotation phase advanced rather than the main lock phase in the internal combustion engine when the internal combustion engine is started with an ambient temperature lower than the present temperature.
