variable speed belt drive

A timing belt is a toothed, rubber belt that connects the crankshaft to the camshaft in an engine. It is designed to transmit rotational motion and maintain the timing relationship between the crankshaft, which drives the pistons, and the camshaft, which operates the intake and exhaust valves. In most modern vehicles, the timing belt is situated behind various components under the engine cover, making it less visible but still crucial for engine operation.

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.
