How to Distinguish China VI Standard Vehicles?
2 Answers
Distinguishing China VI standard vehicles can be done through the following methods: 1. Vehicle conformity certificate; 2. Environmental protection information accompanying vehicle list; 3. Vehicle frame number. The full name of the China VI standard is the National Sixth Stage Emission Standards for Motor Vehicles, which regulates the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and carbon smoke emitted from vehicle exhaust. The key specifications of the China VI standard include: 1. Carbon monoxide emission limit of 700mg; 2. Non-methane hydrocarbon emission limit of 68mg; 3. Nitrogen oxide emission limit of 60mg; 4. Fine particulate matter emission limit of 4.5mg.
Identifying China 6 vehicles is my specialty. When inspecting a car, first glance at the windshield corner or door frame—the yellow emission label marked "China VI" is unmistakable. Check documents too: the "Emission Standard" field on new vehicle conformity certificates or used car registration clearly states China 6a or 6b. My go-to method? Use a mobile app or website to verify the 17-digit VIN (found on the dashboard or door frame)—official databases reveal the truth instantly. Production year matters: post-July 2019 for 6a, post-July 2020 for 6b. China 6 models typically have added exhaust treatment systems, making them low-emission-zone friendly. Last time I helped a neighbor car-shopping, we nearly fell for a China 5 model—VIN check saved the day. Eco-compliance equals long-term savings.
