The timing chain is a crucial component in an internal combustion engine, responsible for synchronizing the rotation of the crankshaft and camshaft. Unlike a timing belt, a timing chain is made of metal and is designed to last longer, often for the lifetime of the engine. It ensures that the engine's valves open and close at the correct times during each cylinder's intake and exhaust strokes, which is essential for optimal engine performance. Regular maintenance is necessary, as a worn or damaged timing chain can lead to significant engine problems, including misfires and catastrophic engine failure.
