通过采用开发的简易磨耗试验机，对排气门和气门座进行磨耗试验的结果表明，气门和气门座在冲击载荷作用下，在落座面上产生微小的相对滑动是导致发生磨耗的主要原因。磨耗值的大小取决于滑动量的多少。落座面上的摩擦系数和落座时的接触位置对滑动量有显著影响。在试验机上对气门和气门座试片进行150万次冲击循环试验结果表明，在正常接触状态下，气门和气门座的磨耗构极小，但在偏心接触时，磨耗量就急剧增大。
The results of wear tests on the exhaust valve and the valve seat by using the developed simple abrasion tester show that the slight relative sliding of the valve seat and the valve seat on the seating surface under the impact load is the main cause of the abrasion. The size of the wear value depends on the amount of slip. The coefficient of friction on the seating surface and the contact position at seating have a significant effect on the amount of slippage. In the test machine on the valve and the valve seat test piece 1.5 million times the impact test results show that in normal contact state, valve and valve seat wear structure is minimal, but in the eccentric contact, the wear increased rapidly.
