The exhaust valve is a key part of diesel engine and it has high failure rate. If it were invalid, the performance of diesel would become worse.

气门是柴油机的关键部件之一，故障率较高，如果出现故障将严重影响柴油机的性能。

Finally, experiments and analyses in valve gear vibration and noise are conducted by means of the advanced measuring and processing instruments. Especially, the noise caused by valve setting is separated and analysed from the total noise, such work has never been done before. The conclusions are significant for reducing vibration and noise of valve gear.

本文使用目前国际上先进的测试、分析仪器对配气机构的振动、噪声进行了实验和分析，特别是在噪声分析上设法将气门的落座噪声分离出来，专门地进行了分析，这在配气机构的噪声分析上还是第一次，得到了一些有意义的结论，为配气机构的减振、降噪提供了依据。
