Does the Langdong engine use a timing belt or chain?

[LeValeria]

Langdong engine uses a timing chain. Timing belt: The timing belt is an important component of the engine's valve system, ensuring accurate intake and exhaust timing by connecting to the crankshaft and maintaining a specific transmission ratio. Belts are used instead of gears for transmission because they produce less noise, have smaller variations, and are easier to compensate for. Obviously, the lifespan of a belt is shorter than that of metal gears, so it needs to be replaced regularly. Timing chain: The timing chain is a high-strength metal chain that connects the sprockets of components such as the crankshaft and camshaft, keeping them synchronized.
