In a piston engine, a timing belt is a toothed belt that drives the camshaft and synchronizes its rotation with the crankshaft propelling it. This synchronisation ensures that the engine's valves open

A toothed rubber timing belt, also known as a synchronous belt, is a crucial component in an internal combustion engine. It is made of durable rubber and features teeth on its inner surface that mesh with corresponding grooves on the crankshaft and camshaft pulleys. These teeth ensure precise synchronization between the rotation of the crankshaft and camshaft, which is essential for the correct timing of the engine's valves in relation to the movement of the pistons.

A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are
