What is the lifespan of the timing chain in the third-generation EA888 engine?

[EleanorAnn]

The timing chain in the third-generation EA888 engine needs to be replaced after driving 60,000 kilometers. This is because the tensioner will be lifted after 60,000 kilometers, which may affect the timing chain's tooth skipping disorder and even pose the risk of lifting the cylinder and valves. Introduction to Timing Gears: Timing gears are mechanical devices that can position related control functions according to a time scale. They are used in internal combustion engines, clocks, and other partial systems with sequential relationships to complete mechanical functions, such as intake and exhaust systems. Timing Gear Transmission Methods: There are three transmission methods for timing gears: chain drive, toothed belt drive, and gear drive.
