What is China VI Emission Standard?
1 Answers
VI refers to the China VI Emission Standard, which is the sixth-stage national standard for motor vehicle pollutant emissions. The formulation of the 'China VI' standard is based on the needs of China's national conditions, while incorporating both European and American standards. It no longer differentiates requirements between gasoline and diesel vehicles, meaning the 'China VI' standard surpasses 'Euro VI' to become one of the world's most stringent tailpipe emission standards. Below is relevant information about the 'China VI' standard: 1. Emission Limits: The 'China VI' standard is an upgrade from 'China V', imposing stricter controls on pollutant emissions. Specifically, it reduces carbon monoxide emissions from gasoline vehicles by 50%, total hydrocarbons and non-methane hydrocarbon emissions by 50%, and tightens nitrogen oxide emission limits by 42%. 2. Implementation Timeline: The 'China VI' standard is divided into two phases—6A and 6B. The first phase, starting July 1, 2020, prohibits the sale, registration, and licensing of vehicles below the 6A emission standard. The second phase, beginning July 1, 2023, extends this prohibition to vehicles below the 6B emission standard. However, these dates represent the national timeline, and some regions have already decided to implement the standard ahead of schedule.
