What is one effect of maintaining proper valve timing?

Maintaining proper valve timing is crucial for maximizing an engine's performance and efficiency. When the valves open and close at the correct moments in relation to the position of the piston, it allows for optimal air-fuel mixture intake and exhaust gas expulsion. This leads to a more complete combustion process, resulting in improved power output.

Optimal power output means that the engine can produce the most work with the least amount of wasted energy. When valve timing is off, it can lead to poor engine performance, including loss of power and efficiency. Therefore, by ensuring that valves are properly timed, the engine operates more effectively, providing the maximum amount of energy possible for its design specifications.

This is why maintaining proper valve timing directly correlates to optimal power output in an engine.
