How many kilometers should the timing chain of the EA111 be replaced?
1 Answers
The timing chain of the EA111 should generally be replaced when the vehicle has traveled between 60,000 to 100,000 kilometers. Lifespan of the timing chain: The lifespan of the timing chain is closely related to the engine oil used for regular maintenance. It offers more reliable transmission and better durability, requiring longer maintenance intervals. Compared to timing belts, timing chains have a longer lifespan and higher reliability. Additionally, timing chains can be tensioned using a tensioner to maintain an appropriate preload, and they can even be designed for lifetime maintenance-free operation. Function of the timing chain: The timing chain is a critical component of the engine. Its primary function is to drive the engine's valve train, ensuring that the intake and exhaust valves open and close at the correct times to allow the engine's cylinders to intake and exhaust air properly. The timing chain operates by connecting the sprockets of components like the crankshaft and camshaft with high-strength metal chains, keeping them synchronized. Due to the high-speed movement between metal parts, which leads to rapid wear and high temperatures, a corresponding lubrication system must be designed to provide cooling and lubrication.
