What Does Vehicle Emission Standard Mean?

[LeCarson]

Vehicle emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, PM particles, soot, etc. Vehicles are mobile sources of pollution, emitting primary pollutants such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter, all of which are environmental contaminants that need to be controlled. The sources of vehicle pollutant emissions come from the exhaust pipe, crankcase, and fuel system. To curb the generation of these harmful gases and encourage automobile manufacturers to improve their products to reduce the sources of these emissions, both Europe and the United States have established relevant vehicle emission standards. The European standards are the benchmarks that China references for its vehicle emission standards, and domestically produced new vehicles will indicate the European standard that their engine emissions comply with.
