From Which Year Did China 5 Vehicles Begin?
2 Answers
China 5 emission standard vehicles started production in 2012 and were implemented in 2013. The China 5 vehicle emission standards mainly refer to HC emission values below 0.1g/km, CO emission values below 1.0g/km, NOx emission values below 0.06g/km, and PM requirements below 0.005g/km. Here is a brief introduction to the content stipulated by the China 5 emission standard: 1. Applicable to light-duty vehicles powered by spark-ignition engines or compression-ignition engines with a maximum design speed greater than or equal to 50km/h. 2. For light-duty vehicles equipped with spark-ignition engines. Emission limits and measurement methods for exhaust pollutants, crankcase pollutants, and evaporative pollutants under normal and low temperatures, durability requirements for pollution control devices, as well as technical requirements and measurement methods for the On-Board Diagnostics (OBD) system. 3. For light-duty vehicles equipped with compression-ignition engines. Emission limits and measurement methods for exhaust pollutants under normal temperature, durability requirements for pollution control devices, as well as technical requirements and measurement methods for the On-Board Diagnostics (OBD) system. 4. Specifies the requirements for type approval of light-duty vehicles, the inspection and determination methods for production consistency and in-use compliance. 5. Specifies special requirements for light-duty vehicles fueled by LPG or NG. 6. Specifies the type approval procedures for replacement catalytic converters intended to be installed on light-duty vehicles as independent technical assemblies in terms of pollutant emissions.
Speaking of when China V emission standards started, I remember it was a story from 2016. To be more specific, in January 2016, major cities like Beijing and Shanghai first piloted the implementation, mainly targeting gasoline-powered passenger cars. By July 2017, it had been rolled out nationwide. Why the rush? At that time, air pollution was severe, and the government wanted to restrict harmful gases in vehicle emissions, reducing substances like nitrogen oxides to about half the level of China IV standards. If you're buying a used car, pay attention—most vehicles manufactured before late 2015 are China IV compliant, making urban registration quite troublesome as many places enforce strict restrictions. These timeline changes happened frequently, with China VI standards following soon after. Policy shifts have significantly impacted the entire auto market, causing rapid depreciation of older vehicles and relatively smaller price increases for new ones.
