The primary function of the internal timing belt is to synchronize the rotation of the crankshaft and camshaft. This synchronization is essential for the timing of the engine's valve openings and closings in relation to the position of the pistons. When the crankshaft rotates, the timing belt transfers that motion to the camshaft, which controls the intake and exhaust valves. Proper timing enables the engine to run smoothly, improve fuel efficiency, and increase overall performance.

The timing belt is a rubber belt featuring teeth, which provides a secure grip on the gears it engages. Typically found in four-stroke internal combustion engines, it is designed to withstand both heat and stress while operating. The timing belt drives the camshaft, which controls valve operation, while the crankshaft generates the power that propels the vehicle. This synchronization is crucial; if the timing belt fails, it can lead to catastrophic engine damage.
