What is the emission symbol for China VI?

[MacRylee]

China VI emission standard, also known as the National Sixth Stage Emission Standard for Motor Vehicle Pollutants, is a standard established to prevent motor vehicle pollution emissions and improve ambient air quality. Below is a partial introduction to the China VI standard: 1. In the China VIa emission standard, the carbon monoxide emission limit for gasoline and diesel vehicles is set at 0.5g per kilometer. China VIa adopts the minimum limits of the China V standard, while China VIb represents the true China VI emission standard, with stricter control over nitrogen oxide emissions. 2. The China VI emission standard is an upgraded version of the current China V emission standard. It imposes more stringent limits on emissions of CO (carbon monoxide), THC (total hydrocarbons), NMHC (non-methane hydrocarbons), NOX (nitrogen oxides), and PM (particulate matter mass) compared to the China V standard. Additionally, it introduces new regulations on PN (particulate matter number) emissions.
