When was China IV emission standard implemented?
2 Answers
Vehicles produced after 2011 comply with China IV emission standards. The China IV standard was implemented nationwide on July 1, 2010. Compared with China III, the China IV standard features upgraded exhaust after-treatment systems, reducing pollutant emissions by 50% to 60% compared to China III. Below are relevant details: 1. Emission standards: As global environmental pollution becomes increasingly severe, countries worldwide are implementing stricter emission standards, which significantly benefits environmental protection. 2. Exhaust treatment: Under stringent emission standards, automakers actively develop new technologies to reduce engine exhaust emissions.
I'm an experienced driver, having driven from the era of gasoline cars to the current age where electric vehicles are everywhere. The implementation of the China IV emission standards was phased, with diesel vehicles taking the lead and being enforced nationwide in July 2011, while gasoline vehicles followed two years later, with strict enforcement starting in July 2013. This standard had a relatively long grace period, and in some remote areas, China III vehicles could still be purchased as late as 2014. Nowadays, China IV vehicles are much rarer on the road, and even in the used car market, they're hard to find, especially since environmental regulations have become stricter, and China VI-B has become the mainstream. A couple of years ago, China IV vehicles could still be transferred across cities, but now, regions like Beijing-Tianjin-Hebei and the Yangtze River Delta basically don't allow their registration anymore.
