What is China 6 Emission Standard?
1 Answers
China 6 Emission Standard, also known as the National Sixth Stage Emission Standard for Motor Vehicles, is established to prevent and control motor vehicle pollutant emissions and improve ambient air quality. Below is a partial introduction to the China 6 Standard: 1. In the China 6a emission standard, the carbon monoxide emission limit for gasoline and diesel vehicles is set at 0.5g per kilometer. China 6a generally adopts the lower limits of the China 5 standard, while China 6b represents the true China 6 emission standard with stricter control over nitrogen oxide emissions. 2. The China 6 emission standard is an upgraded version of the current China 5 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) compared to the China 5 standard. Additionally, it introduces new regulations on PN (particle number) emissions.
