What are the emission standards for yellow-label vehicles?
1 Answers
Yellow-label vehicles' emission standards are defined as follows: during exhaust emission testing, hydrocarbons must not exceed 0.66 grams per kilometer, carbon monoxide must not exceed 2.1 grams per kilometer, particulate matter must not exceed 0.1 grams per kilometer, and nitrogen oxides must not exceed 5 grams per kilometer. Yellow-label vehicles is a collective term for gasoline vehicles whose emission levels at new vehicle type approval were below China's National I emission standard and diesel vehicles below National III emission standard. These vehicles typically have high-volume, high-concentration exhaust emissions with poor emission stability. Based on vehicle registration model and environmental protection inspection results for exhaust emissions, yellow-label vehicles are classified into two types of markers: green environmental inspection compliance markers and yellow markers.
