How to distinguish between China IV and China V standards?
1 Answers
The differences between China IV and China V standards are as follows: 1. Release dates differ: China's Phase IV motor vehicle pollutant emission standards were released on December 30, 2005; China's Phase V motor vehicle pollutant emission standards were released on September 17, 2013. 2. Content varies: China IV vehicle emissions mainly include HC (hydrocarbons), nitrogen (nitrogen oxides), CO (carbon monoxide), and particulate matter (PM); China V standards cover nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particulate matter. 3. Stringency differs: Compared to China IV, the new standard reduces NOx emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration of 350,000 units, this is estimated to reduce NOx emissions by approximately 1,000 tons annually. Additionally, China's Phase V emission control levels are equivalent to Europe's currently implemented Euro 5 emission standards.
