power steering pump drive belt

A non-interference engine is designed in such a way that there is enough clearance between the moving parts (the pistons and valves) such that if the timing belt were to fail, these components would not collide. This design feature is particularly advantageous as it provides a safety net for the engine in the event of a timing belt failure. In contrast, an interference engine does not afford this luxury; failure of the timing belt in such engines typically leads to catastrophic damage, including bent valves and damaged pistons, which can result in extensive repair costs.

The belt connects the crankshaft, which is responsible for converting linear motion from the pistons into rotational motion, to the camshaft, which controls the opening and closing of the engine's valves. During operation, as the crankshaft spins, the timing belt rotates, in turn spinning the camshaft. This precise timing means that as the pistons move down to draw in air and fuel, the camshaft opens the valves at exactly the right moment. If this synchronization is off, the engine may not operate efficiently, leading to performance issues or, in extreme cases, severe engine damage.
