自七十年代末期以来,随着我国金属矿山井下无轨柴油采运机械设备的逐步使用和不断推广,带来了柴油机排气时对工作环境的污染问题。因此,目前国内矿用柴油机的制造厂,除了注重提高柴油机的性能指标和可靠性外,同时也在着力解决其废气净化,即采取有效的机内净化措施降低柴油机排气中有害成分的含量。 (一)柴油机废气中有害成分的形成原 Since the late 1970s, with the gradual use and continuous promotion of mine trackless diesel mining machinery and equipment in China's metal mines, it has brought about the pollution of the working environment when diesel engines exhaust. Therefore, at present, domestic manufacturers of mining diesel engines not only pay attention to improving performance and reliability of diesel engines, but also strive to solve the problem of exhaust gas purification, that is, adopting effective in-machine purification measures to reduce harmful components in diesel exhaust. (A) the original formation of harmful components in diesel exhaust
