What is the national emission standard for Automotive IV?

Automotive IV refers to China's National Phase IV Motor Vehicle Pollutant Emission Standard, abbreviated as "National IV Emission Standard" or simply "Guo IV Standard". The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, these standards aim to control and reduce vehicle emissions below specified limits. Compared to the National Phase III standard, the National IV standard requires approximately a 50% reduction in pollutant emissions for light-duty vehicles, a 30% reduction for heavy-duty vehicles, and an over 80% reduction in particulate matter emissions.
