National IV vehicles can be registered in all cities except Beijing, Guangdong, Shanghai, Fujian, Zhejiang, Jiangsu, Shandong, Hebei, and Liaoning. Here is some information about National IV: 1. The National IV emission standard is the fourth phase of China's motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. 2. By applying technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the emission of vehicle pollutants is controlled and reduced to below specified levels.
