What is the cause of the most common valve burn? Valve burn loss is the most common exhaust valve, the basic reason is the valve seat distortion and carbon accumulation.
In addition, such as improper adjustment of valve clearance, excessive wear, etc. can also cause valve burn loss. When the valve seat is twisted, the temperature of the valve seal of the registered Hong Kong company and the local pressure between the valve and the seat increase at the same time. Valve seal surface often appear grooves, by high temperature gas flushing will form a burn-out. When the valve seal surface and valve seat carbon accumulation is serious, so that the heat transfer conditions worsen, but also easy to produce deformation, resulting in valve burn loss.
