    1. The camshaft timing gear assemblies each consist of an outer housing that is driven by the timing chain sprocket, and a vane sub-assembly that is coupled to each camshaft.

    2. The camshaft timing gear assembly uses a vane sub-assembly with 3 lobes.

    3. When the engine stops, each camshaft timing gear assembly is locked at the most retarded angle by its lock pin. This ensures excellent engine startability.

    4. The oil pressure sent from the advance or retard side passages of the intake camshafts causes rotation of the vane sub-assembly relative to the timing chain sprocket, varying the valve timing continuously.
