When did the China 5 vehicle emission standards start?
2 Answers
China 5 vehicle emission standards were fully implemented nationwide in July 2017. The emission control level of China 5 standards is equivalent to the Euro 5 emission standards implemented in Europe. China 5 vehicles refer to those that comply with the 'National Fifth Stage Emission Standards for Motor Vehicle Pollutants.' The motor vehicle pollutant emission standards were established to enforce environmental protection laws, reduce and prevent vehicle exhaust pollution, protect the ecological environment, and ensure human health. Compared to China 4 standards, China 5 standards can reduce nitrogen oxides from vehicles by 25% to 43%, significantly improving environmental efficiency.
I remember the China 5 vehicle emission standards were implemented in 2017, mainly targeting newly registered light-duty gasoline and diesel vehicles. As a car mechanic back then, I encountered vehicles needing exhaust treatment devices like catalytic converters and particulate filters every day – much stricter than the previous China 4 standards. The pollutant limits were significantly reduced, requiring better control of PM2.5 and nitrogen oxides to pass road tests. Air quality did improve after implementation, with less severe smog in Beijing. Car buyers should note that only China 5 compliant vehicles launched after 2017 meet these standards – older vehicles face driving restrictions in major cities. Though the 2020 China 6 standards became even stricter, the China 5 upgrade was quite practical. Just remember to inspect emission systems during maintenance to prevent malfunctions.
