Abstract
An internal combustion engine includes a variable valve timing mechanism. The variable valve timing mechanism includes a first member configured to rotate according to rotation of a crankshaft, a second member configured to be displaced relative to the first member between a most retarded angle position and a most advanced angle position, and a lock pin configured to engage with the first member and the second member. When displacing the second member from an initial angle, the variable valve timing mechanism supplies oil pressure such that the lock pin moves to a position where the lock pin disengages from the first member and the second member. A valve rest mechanism is capable of performing a rest operation when a displacement angle of the second member relative to the first member is equal to or more than a prescribed waiting angle displaced relative to the initial angle.
