Checking the timing on a car refers to the process of verifying and adjusting the timing of the engine’s components, primarily the ignition timing and valve timing, to ensure optimal performance and efficiency.
Correct timing is crucial for several reasons. It optimizes the engine’s combustion process, leading to improved power, fuel economy, and reduced emissions. Moreover, it helps prevent engine damage by ensuring that valves open and close at the appropriate moments in relation to the piston’s movement.
