Is the Besturn B30 equipped with a timing belt or chain?

Besturn B30 adopts a chain. Introduction to timing belts: The timing belt is a crucial component of the engine's valve system. It connects to the crankshaft and ensures the accuracy of intake and exhaust timing through a specific transmission ratio. Belts are used instead of gears for transmission because they produce less noise, have minimal self-variation, and are easier to compensate. However, it is evident that the lifespan of a belt is shorter than that of metal gears, necessitating regular replacement. Introduction to chains: Chains are typically made of metal links or rings and are commonly used for mechanical transmission and traction. They can also serve as barriers for traffic channels (such as on streets, rivers, or harbor entrances) and are used for mechanical transmission purposes.
