在地下矿和隧道等场合使用的柴油机动力装置,如机车、汽车、铲运机以及其它各种以柴油机为动力的自行设备,其废气对作业环境的污染问题是从两方面来解决的。一方面,通过机内净化措施最大限度地降低柴油机排出的废气有害物质浓度;另一方面,采取稀释措施,使废气——稀释空气混合气中的有害物浓度降
Diesel engine power plants used in underground mines and tunnels, such as locomotives, automobiles, scrapers and other diesel-powered self-propelled equipment, solve the problem of exhaust pollution on the working environment in two aspects. On the one hand, by means of in-plant purification measures, the concentration of harmful substances emitted by diesel engines is minimized; on the other hand, dilution measures are taken to reduce the concentrations of harmful substances in the exhaust gas and the dilution air mixture
