对于地下矿用柴油机,如地下金属矿和地下煤矿用柴油机,国际上已有许多国家,如美国、英国、加拿大、西德、苏联、澳大利亚、南非等,制订了相应的排放标准.地下矿用柴油机的排放标准与汽车用柴油机的排放标准相比,在试验方法和极限值上均有很大不同.它的试验方法比汽车用柴油机的简单得多,但极限值却更为严格.表1是世界各国地下矿用柴油机排放标准一览表.下面简要地介绍一些主要国家的地下矿用柴油机排放标准.
For underground mining diesel engines, such as underground metal mines and underground coal mine diesel engines, there are many countries in the world, such as the United States, Britain, Canada, West Germany, the Soviet Union, Australia and South Africa, have formulated corresponding emission standards. Diesel engine emission standards and emission standards for automotive diesel compared to the test methods and limits are very different.Its test method is much simpler than the automotive diesel engine, but the limits are even more stringent Table 1 Is a list of emission standards for underground mining diesel engines in various countries of the world.The following is a brief introduction of the emission standards for underground mining diesel engines in some major countries.
