Construction VVTi Controller

► This controller consists of the housing driven from the timing chain and the vane coupled with the intake camshaft.

► The oil pressure sent from the advance or retard side path at the intake camshaft causes rotation in the VVT-i- controller vane circumferential direction to vary the intake valve timing continuously. When the engine is stopped, the intake camshaft will be in the most retarded state to ensure startability. When hydraulic pressure is not applied to the VVT-i controller immediately after the engine has been started, the lock pin locks the movement of the VVT-i controller to prevent a knocking noise.
