ENGINE UNIT


  1. CONSTRUCTION


    1. This VVT-i controller (camshaft timing gear assembly) consists of the housing driven from the timing chain and the vane coupled with the camshaft (intake).

    2. The oil pressure sent from the advance or retard side path at the intake camshaft causes rotation in the VVT-i controller (camshaft timing gear assembly) vane circumferential direction to vary the intake valve timing continuously.

    3. When the engine is stopped, the camshaft (intake) will change to the most retarded state to ensure startability.

    4. When hydraulic pressure is not applied to the VVT-i controller (camshaft timing gear assembly) immediately after the engine has been started, the lock pin locks the movement of the VVT-i controller (camshaft timing gear assembly) to prevent a knocking noise.
