摘　　要：介绍了中型以上货车或客车用空压泵现状、存在的常见问题及其原因分析;通过我司的一个实例和相关的试验和测试方法分别研究了提高压缩比、增大排气量对柴油机用空压泵性能的改善情况:缩短充气时间,控制排气温度,减少窜油量的影响和作用,并通过试验数据对比了两种方案;同时为整车用户提出了一些应对建议;最后阐述了结论。The statur of air compressors for medium-duty vehicles and buses, as well as the common problems and causes of air compressors are presented. Two ways of improving air compressor performance e. g. increasing the compression ration and the displacement of air compressor are analyzed, tested, verified and compared in terms of shorting of air charging time, reducing of exhaust temperature and oil carry-over. Based on the analysis and test results, suggestions on how to choose a proper air compressor are put forward for users.
