valve timing

**Valve Timing**

Valve timing refers to the precise timing of the opening and closing of the engine’s intake and exhaust valves during the combustion cycle. It plays a crucial role in optimizing engine performance, fuel efficiency, and emissions. Proper valve timing ensures that the air-fuel mixture enters the combustion chamber at the right moment and exhaust gases exit efficiently, contributing to smoother engine operation and increased power output. Adjustments in valve timing are often made through technologies such as variable valve timing (VVT) to enhance performance across different engine speeds and loads.
