Valve cylinder head is one of the widely used drives in automobiles, and it mainly has the following functions:

1. PCV (Positive Crankcase Ventilation) Valve: Regulates crankcase pressure by rerouting blow-by gases back to the intake. Prevents oil leaks and excessive pressure buildup. Reduces emissions and maintains engine efficiency.
2. VVT (Variable Valve Timing) Solenoid: Adjusts camshaft timing for better fuel efficiency and performance. Helps with smoother idling and optimized power output.
3. EGR (Exhaust Gas Recirculation) Valve: Recirculates exhaust gases back into the intake to lower NOx emissions. Improves fuel efficiency and meets emission regulations.
4. Secondary Air Injection Valve: Injects fresh air into the exhaust system to reduce emissions at cold start. Helps catalytic converter reach optimal temperature faster.
