What are the emission standards for China VI vehicles?
2 Answers
China VI standard refers to the vehicle emission standards. Compared with the "China V" standard, "China VI" will strictly control the emission limits of pollutants. Under the exclusion of working conditions and test influences, the carbon monoxide emissions of gasoline vehicles are reduced by 50%, the emission limits of total hydrocarbons and non-methane hydrocarbons are reduced by 50%, and the nitrogen oxide emission limits are tightened by 42%. The implementation time of China VI emission standards is divided into two phases: 1. The first phase: From July 1, 2020, all sold and registered vehicles must meet the China VI A standard. 2. The second phase: From July 1, 2023, all sold and registered vehicles must meet the China VI B standard; some cities will implement the China VI light-duty vehicle emission standards in advance.
The car I'm driving now meets the China 6 emission standard, which is actually the National Sixth Stage Emission Standard for motor vehicles, specifically designed to control the emission of pollutants from vehicle exhaust. It's much stricter than the previous China 5 standard, with the limit values for harmful gases like carbon monoxide and hydrocarbons reduced by an average of 50%. Particularly, it introduces real driving emission tests to prevent manufacturers from only meeting standards in laboratory conditions. China 6 is further divided into two phases, 6a and 6b, with 6b being even more stringent. Once fully implemented, all new vehicles must comply to be registered. I think the introduction of this standard is a good thing—at least there aren't as many trucks belching black smoke on the roads anymore, and the air quality in our city has noticeably improved a lot.
