What is China VI?
2 Answers
"China VI" emission standards, the full name of which is National Sixth Stage Emission Standards for Motor Vehicle Pollutants, is an upgraded standard based on the domestic situation of China, building upon the "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China V)". Here is an introduction to the new China VI standards: 1. Addition of OBD (On-Board Diagnostics) checks. If a vehicle's fault light is on or fault codes are detected in the engine system, it will be deemed unqualified and fail the annual inspection. 2. Introduction of checks for the readiness status of the engine system, such as whether the oxygen sensor is in a ready state or if the three-way catalytic converter has reached readiness. If these components are not in a ready state, the vehicle will not pass the annual inspection. 3. While China V standards used the NEDC (New European Driving Cycle) for both emission and fuel consumption tests, China VI standards continue to use NEDC for fuel consumption tests but adopt the more stringent WLTC (Worldwide Harmonized Light Vehicles Test Cycle) as the emission test cycle.
China VI is an automotive emission standard implemented in China, aimed at making vehicle exhaust cleaner. I remember first hearing about it at an auto show, where a salesperson mentioned that China VI-compliant vehicles can help reduce air pollution by imposing stricter controls on harmful substances like carbon monoxide and nitrogen oxides. Nowadays, most cars on the market are China VI-compliant, and it's essential to look for this label when buying a new car. Although the price might be slightly higher, these vehicles are more fuel-efficient in the long run and help reduce smog. After switching to a China VI-compliant car myself, I’ve noticed the exhaust fumes are much less pungent, making it more pleasant to drive with the windows down. I always advise friends to prioritize China VI-compliant cars when shopping for a new vehicle—it’s both eco-friendly and practical, benefiting urban environments and public health. After all, no one wants to breathe polluted air every day.
