Not all timing chains are maintained, the difference between the three chains

Not all timing chains are maintained, the three chains in my hands are in front of everyone. The chains on these three engines, this one is the EA837 engine, and its chain structure is similar to that of motorcycles and bicycles. What about these two other engines? It's the EA888, second-generation engine, and EA888 third-generation engine. The distinction between these two engines is actually very simple. The engine oil cap is located in this position, and the second generation engine has a larger oil cap,

What about this engine? The oil cap is relatively small at the head of the engine. What about this? It's the third-generation engine.

A video shows that everyone has figured out which of these three engines is a chain and truly maintenance free. What about these three engines? It is equipped in various models such as Volkswagen, Audi, and Porsche. Now let's talk about the timing chain of this EA888 second-generation engine. The chain is very thin when removed, and the principle of this chain is similar to that of a timing belt. It is fastened to this chain, and what about this chain? It doesn't take up space, and the working noise is very low. However, from our observation afterwards, the average service life of this chain is about 100000 kilometers, which was around 100000 kilometers. If you want to know if the chain has been stretched, the engine inspection computer did not confirm the deviation angle. If it exceeds 4 degrees, it indicates that the chain of this car has been changed.

EA888， The chain of the third-generation engine has been strengthened. Let's take a look at the differences between the second and third generations. The thickness of this steel plate in the third-generation chain has become thicker, and it looks more sturdy. The chain life of third-generation engines is much longer than that of second-generation engines, with a general service life of at least 150000 kilometers or even more, exceeding 200000 kilometers.

Let's take a look at the chain of this 6-cylinder engine again. What is the comparison between the chain of a 4-cylinder engine and the chain of a 6-cylinder engine? It is obvious that the chain of a six cylinder engine is thicker, and what is the structure of this chain? It's a bit like the chain of a motorcycle or bicycle. From our after-sales observation, the chain of this engine can indeed achieve lifelong maintenance free and engine lifespan. What about models with a mileage of over two to three hundred thousand kilometers? It also did not cause chain wear, so it is truly maintenance free.

So do you know if your car is a timing belt or a timing chain. Let's go communicate now.
