The timing belt is a critical component of an internal combustion engine. It is a rubber belt with teeth that connects the crankshaft to the camshaft. The primary role of the timing belt is to synchronize the rotation of these two shafts; this ensures that the engine's valves open and close at the correct times during each cylinder's intake and exhaust strokes. A properly functioning timing belt is essential for optimal engine performance and efficiency.
