ENGINE UNIT DETAILS CAMSHAFT TIMING SPROCKET

CONSTRUCTION

1. The camshaft timing sprocket assembly consists of an outer housing that is driven by the timing chain sprocket, and a vane that is coupled to the camshaft.

2. The camshaft timing sprocket assembly uses 3 vanes.

3. When the engine stops, the camshaft timing sprocket 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 camshaft causes rotation of the vane relative to the timing chain sprocket, to vary the valve timing continuously.
