What Does Car Timing Mean?
1 Answers
Car timing refers to the mechanism that drives the engine's valve train, ensuring that the engine's intake and exhaust valves open and close at the appropriate times to allow the engine cylinders to properly intake and exhaust air. Below is a detailed introduction to car timing: Valve Timing: The valve train (including components such as the camshaft, valves, and rocker arms) supplies the combustible air-fuel mixture to the cylinders at precise times and exhausts the waste gases at precise times. Ignition Timing: The combustible air-fuel mixture in the cylinders is ignited at the exact time to drive the pistons and perform work. The ignition timing of a car varies depending on the engine type and the fuel used. The purpose of adjusting and correcting the ignition timing is to achieve the optimal "timing" or initial "ignition advance angle" for the best engine performance.
