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.

Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

A method of determining a sliding camshaft actuator pin position based on engine crankshaft angle includes commanding a sliding camshaft actuator to perform a valve step shift, and monitoring an actuator's pin position during the valve step shift command. At least one crank angle is measured when the actuator pin position reaches or exceeds at least one predetermined pin position threshold and at least one remedial action is performed when the actuator pin position does not correlate to the at least one measured crank angle.
