Automobile emission standard

The vehicle emission standard refers to the regulation of harmful gas contents such as CO (carbon monoxide), HC + NOx (hydrocarbons and nitrogen oxides), and PM (fine particles, soot) discharged from automobile exhaust gas. From January 1, 2004, Beijing will change the exhaust emission standard for motor vehicles from the current European I to Europe II. By 2008, the European No. III standard will be officially implemented.

The European Standard is implemented by the European Economic Commission (ECE) emission regulations and the European Community (EEC) emission directives. The European Community (EEC) is the European Union (EU). Emission regulations are voluntarily recognized by ECE participating countries, and emission directives are enforced by EEC or EU participating countries. European regulations (instructions) for vehicle emissions have been implemented several stages before 1992. Europe has been implementing Euro I (European Type I certification emission limits) since 1992 and Euro II (European Type II certification and production since 1996). Consistent emission limits have been implemented since 2000. Euro III (Euro III certification and production consistency emission limits) have been implemented since 2000, and Euro IV (Euro IV certification and production consistency emission limits) have been implemented since 2005.
