Why valve timing is important?

Valve timing is crucial in an internal combustion engine as it determines the precise moment when the intake and exhaust valves open and close during the engine cycle. Proper valve timing optimizes engine performance, efficiency, and power output by ensuring that air and fuel mixture enters and exhaust gases exit at the right times. It also helps prevent engine knocking and reduces emissions, contributing to overall engine longevity and environmental compliance. Misaligned valve timing can lead to decreased performance and potential engine damage.
