toothed belt and pulley

A timing belt is a looped belt made of reinforced rubber or urethane with teeth that mesh perfectly with the teeth on the gears of the pulleys. The primary function of the timing belt is to synchronize the rotation of the crankshaft and camshaft in an internal combustion engine, ensuring that the engine's valves open and close in time with the movement of the pistons. This synchronization is critical for optimal engine performance and efficiency, preventing any potential interference that could lead to engine damage.

A properly functioning timing belt is critical for the operation of an internal combustion engine. If the belt were to slip or break, it could lead to catastrophic engine failure. In interference engines, where the transmission allows for overlapping movements between the pistons and valves, a timing belt failure can result in the pistons striking the valves. This can cause significant damage and lead to costly repairs, making regular maintenance of the timing belt vital.
