What is the meaning of China III and China IV in automobiles?
1 Answers
China III and China IV refer to automobile exhaust emission standards. The domestic emission standards are mainly based on the European Union emission standards, with modifications to adapt to national conditions and practical needs. The following is an introduction to the China III and China IV emission standards: Introduction to China III emission standards: China III vehicles refer to those that comply with the China III emission standards. After 2011, vehicles meeting the China III emission standards could no longer be sold or registered, but those already registered could continue to be used. The vehicle's emission standard can be determined by checking its environmental label. Introduction to China IV emission standards: Starting from May 1, 2018, the application for China III products was discontinued, and only applications for China IV products were accepted. After July 1, 2018, no announcements for China III models were issued. When applying for the announcement of China IV models, new model specifications should be used to distinguish them from China III models. As the new standards have already specified technical routes, China IV models no longer provide separate recommended technical solutions and should strictly comply with the standard requirements.
