[Sophie]

China VI is equivalent to China 6, which refers to the China 6 National Standard for Vehicle Pollutant Emissions, abbreviated as the China 6 standard. Vehicle emission standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot. The China 6a standard specifies the following limits: 1. Gasoline vehicles must not emit more than 700mg of carbon monoxide per kilometer driven; 2. Gasoline vehicles must not emit more than 68mg of non-methane hydrocarbons per kilometer driven; 3. Gasoline vehicles must not emit more than 60mg of nitrogen oxides per kilometer driven; 4. Gasoline vehicles must not emit more than 4.5mg of PM (particulate matter) per kilometer driven.
