The timing chain is a crucial component in an internal combustion engine, serving to synchronize the rotation of the crankshaft and camshaft. Unlike a timing belt, a timing chain is made of metal and is designed for durability and longevity. It plays a vital role in ensuring that the engine's valves open and close at the proper times during the intake and exhaust strokes. Regular maintenance is essential, as a worn or damaged timing chain can lead to severe engine damage. Most modern engines use timing chains due to their reliability, making them an integral part of automotive engineering.
