What is the National Standard Level of National V (National 5)?
1 Answers
National V (National 5) belongs to the National 4 vehicle category, meaning it meets the National 5 standard. Below are detailed introductions regarding National 4 and National 5 standards: 1. National 4: The sulfur content limit in National 4 standard gasoline is 150mg/kg. The National 4 emission standard is the fourth phase of China's national standards for motor vehicle pollutant emissions. It controls and reduces vehicle emissions to below specified levels through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices. 2. National 5: The sulfur content limit in National 5 standard gasoline is 50mg/kg. The National 5 emission standard is equivalent to the Euro V standard, which was officially implemented in Europe starting from September 1, 2009. In 2012, Beijing planned to implement the National V standard. Once fully implemented, vehicles that do not meet this emission standard would not be allowed to be sold in Beijing. To support the implementation of the National V emission standard, Beijing also planned to further improve fuel quality to align with the National V standard.
