When did China 5 start?
2 Answers
China 5 was implemented nationwide from January 1, 2017. More information about China 5 is as follows: 1. China 5 is the fifth phase of the national motor vehicle emission standards, equivalent to the fifth phase of emission standards implemented in Europe. From China 1 to China 5, each increase in the standard reduces vehicle pollution by 30% to 50%. 2. Compared with the China 4 standard, the China 5 standard reduces harmful gas emissions such as nitrogen oxides from heavy-duty vehicles by 43%, and new standard light-duty vehicles reduce harmful gas emissions such as nitrogen oxides by 25%. This not only greatly improves the environment but also benefits everyone's health.
As an automotive technology enthusiast, I always delve into the details of new emission standards. The China V emission standard was officially implemented in China starting from 2017. Specifically for light-duty gasoline vehicles, newly produced vehicles had to meet this stricter standard from January 1, 2017. This represented a significant tightening of pollutant limits compared to the previous China IV standard, such as for carbon monoxide and nitrogen oxides, effectively reducing smog and PM2.5 emissions. I remember those years when automakers were busy upgrading engine technologies, adding innovations like catalytic converters, which contributed greatly to environmental improvement. Later, when China VI was introduced in 2019, China V became a crucial transitional period. As a tech-savvy person, I often help friends check the emission dates when buying cars to confirm if vehicles purchased after 2017 meet this standard.
