How long do engine valves last?

Take enough time to talk with car people and car girls, and after all you may hear them talk about valve work - valve work, multi angle valve grinding etc.

Valves are a serious problem. They act as gatekeepers for fuel and air entering and leaving the combustion chambers of automobile engines. If one or more valves are damaged, catastrophic engine failure will also cause problems. Knowing that engine valves are very important, how do you judge that one or more of them got worse? In any case, how long will the engine valve last?

Let's begin with a simple definition. The engine valve consists of a valve stem and an ambiguous head like a mushroom whose lid is upside down. For valves, accuracy is the key to achieving optimum performance. Valve trains (valves, valve springs, rocker arms, guide rails) are swinging in the oil bath every day, but snoring is rare. This is a modern miracle. However, even if the valve is slightly off the valve, problems may arise if the valve opens or closes, or is slightly off the specification.

So how does the valve stop functioning? The list is very wide and the underlying cause of bulb failure often points to a further "upstream" problem - and to understand there are several car investigations required. Here are some partial list of bad things that can happen with engine valves, and why:

If the valve spring or other parts are inappropriate, the valve may open and the piston may be damaged.

An abnormally high operating temperature (for example due to excessive acceleration or hard drive) burns the exhaust valve and causes damage due to thermal stress.

Valves, rails, seals, and other parts have been corrected without having to check the correct dimensions and angles - it could be bent or broken

As you can imagine, some of these effects can affect valves as well as other major engine parts, which can be very expensive. However, there are steps that can be taken to reduce the possibility of some of these bad results. One is to check and replace the timing belt (or chain) as recommended by the car manufacturer. (You can find this information in the original user manual or you can find this information in many model specific service manuals available online at the auto parts store and this is not surprising - It is a regular change paint oil and immediately check for abnormal conditions such as oil leakage and burning.

So, we have not answered this question yet - how long should an engine valve last? In that case, the life of the engine valve is not fixed. Ultimately, theoretically, if the length of the drive is long enough, the valve will wear. It depends on how well it is made, the difficulty of work, the overall car maintenance, and the relationship with other parts of the engine like the timing belt, for example

We need to consider further: How does valve material interact with blood? (Consideration of clot) How long can such valves last? How much does this valve move between each heartbeat? Do you need to replace the other valves in the heart? Can you push such a valve into a smaller delivery catheter? However, part of the reason for coming here is to make it possible to see the actual anatomical structure without remembering many marked areas. This may be difficult to obtain. Our laboratory is doing our best to solve this problem. The functional heart video here comes from the human heart anatomy of the visible heart research laboratory, but there are still many things to do.
