VALVE TIMING ADJUSTING DEVICE

摘要

PROBLEM TO BE SOLVED: To perform starting suitable for a temperature of an internal combustion engine.SOLUTION: A main lock mechanism 16 locks a rotational phase by fitting a main lock member 160 into a main lock hole 162 at a main lock phase Pm for closing an intake valve 9 at a time later than arrival of a piston 8 at a bottom dead point. A sub-lock mechanism 17 locks a rotational phase by fitting a sub-lock member 170 into a sub-lock hole 172 at a sub-lock phase Ps advanced from the main lock phase Pm. A lock control mechanism 18 opens the main lock hole 162 to thereby allow the rotational phase lock at the main lock phase Pm when a prescribed cold temperature condition is not satisfied in a stopped internal combustion engine, and closes the main lock hole 162 to thereby release the rotational phase lock at the main lock phase Pm when the cold temperature condition is satisfied.
