Ti Controller

• This controller consists of the housing driven by the timing chain and the vane coupled with the intake and exhaust camshafts.

• The intake side uses a VVT-i controller with 3 vanes, and the exhaust side uses one with 4 vanes.

• When the engine stops, the intake side VVT-i controller is locked on the most retarded angle side by the lock pin, and the exhaust side VVT-i controller is locked on the most advanced angle side. This ensures excellent engine startability.

• The oil pressure sent from the advance or retard side path at the intake and exhaust camshaft causes rotation in the VVT-i controller vane circumferential direction to vary the intake valve timing continuously.

• An advanced angle assist spring is provided on the exhaust side VVT-i controller. This helps to apply torque in the advanced angle direction so that the vane lock pin securely engages with the housing when the engine stops.
