2 Answers
China National VI is an emission standard. Below are relevant introductions about the "China National VI" standard: Emission Limits: The "China National VI" standard is an upgrade from the China National V standard. Compared to the "China National V" standard, "China National VI" imposes stricter controls on pollutant emission limits. Specifically, it reduces carbon monoxide emissions from gasoline vehicles by 50%, lowers the emission limits for total hydrocarbons and non-methane hydrocarbons by 50%, and tightens nitrogen oxide emission limits by 42%. Implementation Timeline: According to the plan, the "China National VI" standard will be implemented in two phases: 6A and 6B. The first phase, starting from July 1, 2020, prohibits the sale, registration, and licensing of vehicles that do not meet the 6A emission standard. The second phase, beginning on July 1, 2023, prohibits the sale, registration, and licensing of vehicles that do not meet the 6B emission standard. However, these dates represent the national timeline for achieving the "China National VI" standard, and some regions have already decided to implement this standard ahead of schedule.
