由于排气门排出的是高温高压废气,因此排气门与座的工作条件相当恶劣,一般认为其磨损速度比进气门与座的磨损快,其实恰恰相反,我们在工作中发现许多机型上却是进气门与座的磨损比排气门与座的磨损快些。 Exhaust valve exhaust is due to the high temperature and pressure exhaust, exhaust valve and the seat of the working conditions are rather poor, generally considered wear faster than the intake valve and seat wear faster, in fact, on the contrary, we found many models at work On the other hand, the wear of the intake valve and the seat is faster than that of the exhaust valve and the seat.
