ribbed belt

The timing belt is a crucial part of an internal combustion engine. Typically made from a reinforced rubber compound, it features teeth along its inner side, which interlock with gears on the crankshaft and camshaft. This precise synchronization is vital for the engine's performance because it ensures that the engine valves operate in harmony with the pistons, preventing interference. In interference engines, a timing belt failure can lead to a catastrophic collision between the pistons and valves, causing significant wear and potentially complete engine failure.
