What is the purpose of an automotive timing belt?

The purpose of an automotive timing belt is to synchronize the rotation of the engine's camshaft and crankshaft. It ensures that the engine's valves open and close at the correct time within the engine's combustion cycle, allowing for optimal fuel efficiency, power, and overall engine performance. The timing belt also helps prevent collision between the valves and the pistons, which could cause significant engine damage if not properly timed.
