VTC System
- The VTC system makes continuous intake valve timing changes corresponding to the operation conditions.
- It optimizes intake valve timing to allow the engine to produce maximum power.
- Cam angle is advanced to obtain the EGR effect and reduce the pumping loss. The intake valve is closed quickly to reduce the entry of the air/fuel mixture into the intake port and improve the charging effect.
- Reduces the cam advance at idle, stabilizes combustion, and reduces engine speed. If a malfunction occurs, VTC system control is disabled and the valve timing is fixed at the fully retarded position.
