What are the emission standards for yellow-label vehicles?
3 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.
I've been driving for over twenty years and know quite a bit about yellow-label vehicles. Their emission standards mainly refer to China I emissions, meaning gasoline vehicles that don't meet China I standards and diesel vehicles that don't meet China III standards. To put it simply, these are older vehicles with severely excessive exhaust emissions, emitting way too much nitrogen oxides and particulate matter, causing serious pollution when driven. I remember the government labeled these vehicles with a yellow tag, directly restricting them from driving in urban areas to improve air quality. During regular maintenance, it's best to check the exhaust system. If you notice black smoke, get it repaired or consider replacing the vehicle. I've personally gone through several repairs; adding purification devices can help a bit, but the most effective solution is switching to a new energy vehicle. With environmental policies advancing, we vehicle owners need to keep up with the pace.
I've been dealing with cars for a long time and know that yellow-label vehicles are major pollution sources. They fail to meet emission standards—gasoline cars below China I and diesel below China III, meaning their exhaust treatment can't keep up with the times. These cars spew smoke and are mostly banned in big cities. The government uses color coding for simplicity, but it's really about public health. I suggest everyone pay attention to emission levels during annual inspections. If your car is over 10 years old, consider retiring it. Switching to an eco-friendly car not only saves money and avoids fines but also helps reduce smog in the community. Personally, I recommend installing a catalytic converter, but in the long run, policies favor electric vehicles—responding to that trend is always a good move.
