How to Determine Which National Emission Standard a Vehicle Belongs To?
2 Answers
Knowing which national emission standard a vehicle belongs to can be done through the following methods: 1. Check the vehicle's environmental protection label, which has clear markings on the back; 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire; 3. Take the vehicle registration certificate to the vehicle management office for inquiry; 4. Refer to the vehicle's factory certificate for details. Emission standards refer to the national standards for motor vehicle pollutant emissions, which regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. These standards are categorized by letters: National I, National II, National III, National IV, National V, and National VI.
Last time I was curious about my car's emission standard, I simply checked the vehicle compliance certificate that came with the purchase. It clearly showed the China V label, which was quite convenient. If there's no certificate, you can look for the environmental protection label on the windshield – it's usually stuck there. The production year can also help determine: most cars produced between 2013-2016 meet China V standards. If all else fails, I enter the VIN code on the National Motor Vehicle Environmental Protection website to check, and the results appear immediately. This matters for traffic restriction policies and annual inspections – for example, vehicles below China VI standards often face urban driving restrictions, so knowing early can save trouble. I also think keeping up with new vehicle emission standards is important to help reduce air pollution and protect the environment.
