What Are the Vehicle Environmental Protection Testing Standards?
2 Answers
The environmental protection standards for vehicles had already reached China 6 in 2019. Below is the relevant introduction about vehicle environmental protection testing: 1. Concept: According to the requirements of the "Regulations on the Management of Environmental Protection Inspection Qualification Marks for Motor Vehicles", gasoline-powered vehicles equipped with spark-ignition engines that meet China I or above emission standards, and diesel-powered vehicles equipped with compression-ignition engines that meet China III or above emission standards are classified as green-label vehicles. Those that do not meet the above standards are classified as yellow-label vehicles. 2. Classification: The first category of light-duty vehicles registered after July 1, 2000; the second category of light-duty vehicles registered after October 1, 2001; medium and heavy-duty vehicles registered after July 1, 2003. Diesel vehicles: All vehicles registered after July 1, 2008 are green-label vehicles, while those that do not meet the above standards are yellow-label vehicles.
I know a thing or two about automotive environmental testing standards, having dealt with them quite a bit. The core focus is on exhaust emission testing. China currently implements the China VI standard, while European vehicles follow the Euro VI series. Testing is conducted at designated stations, with the vehicle either idling or running at a constant speed, measuring pollutant limits like carbon monoxide and nitrogen oxides. Exceeding these means failing the test. For instance, China VI is much stricter than older standards, requiring lower emission figures for better environmental protection, but owners of older vehicles may need to spend time repairing their catalytic converters to pass. The testing process is quite quick, usually wrapped up within 20 minutes, though regular vehicle maintenance can help avoid hassles. I think it's a good initiative – the air is getting cleaner.
