ENGINE UNIT


  1. CONSTRUCTION


    1. The camshaft timing exhaust gear assembly consists of a sprocket driven by the No. 2 chain sub-assembly, a housing coupled with the sprocket, and a vane coupled with the exhaust camshafts.

    2. The engine oil pressure sent from the advance or retard side path of the exhaust camshaft causes the camshaft timing exhaust gear assembly vane to rotate which allows for continuous variation of the exhaust valve timing.

    3. As the engine stops, the advance assist spring moves the camshaft timing exhaust gear assembly to the most advanced position. Then, a lock pin locks the vane to the sprocket, in order to ensure engine startability. After the engine is started, engine oil pressure disengages the lock pin.
