Timing belts are timing chains for engines with larger bores and strokes. They play a significant role in how internal combustion engines work. They harmonize camshaft and crankshaft rotation, and if both of these are in sync, the valves and pistons will operate correctly. In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is used to synchronize the rotation of the crankshaft and the camshaft. This synchronization ensures that the engine's valves open and close at the correct times in relation to the position of the pistons.
