Abstract:
An intermediate lock pin (ILP) ILP type variable valve timing unit may include an ILP type stator having at least one chamber formed therein, a rotor accommodated in the chamber to rotate relatively to the ILP type stator, and a lock maintaining portion provided in the chamber to maintain locking of the stator and the rotor when an engine stops working. The ILP type continuously variable valve timing device includes an ILP type variable valve timing unit, an ILP type oil control valve mounted on a cam cap engaged with a cylinder head to operate a lock maintaining portion of the variable valve timing unit, and an ILP type oil flow path branched from a main oil flow path of the cylinder head to guide the supply of oil to the variable valve timing unit through the cam cap and the ILP type oil control valve.
