the serpentine belt

The timing belt is a reinforced rubber belt that drives the camshaft and crankshaft, ensuring that they rotate in sync. In an internal combustion engine, the timing of the valves opening and closing is critical. If the camshaft and crankshaft are not synchronized, it can lead to severe engine damage. The timing belt is usually not visible without disassembling parts of the engine, making its maintenance less straightforward than some other components.

The operation of cogged belts is primarily based on the interlocking design of their teeth. When the belt is driven by a pulley, the teeth fit snugly into the grooves of the pulley, ensuring that there is minimal slippage. This characteristic offers a high degree of accuracy, making cogged belts especially suitable for applications where precise timing is crucial, such as in engine timing systems, where the belt must synchronize the crankshaft and camshaft rotations.
