In a four-stroke engine, the timing belt plays a pivotal role during the intake, compression, power, and exhaust strokes. As the crankshaft rotates due to the combustion process, it drives the timing belt, which in turn rotates the camshaft. This rotation opens and closes the engine's intake and exhaust valves at precisely the right moments, ensuring that air-fuel mixtures enter and exhaust gases exit the combustion chamber efficiently.

A tensioner belt pulley is typically constructed from durable materials such as metal or high-grade plastic, designed to withstand the high temperatures and stresses present in an engine environment. The pulley is mounted on a pivot arm, allowing it to move as the belt tension changes. Most modern tensioners are equipped with a spring mechanism that automatically adjusts the tension on the belt, providing a consistent and precise amount of tension regardless of engine speed or load.
