How to Identify Whether a Car Meets China 6 Emission Standards When Purchasing?

Methods to identify whether a car meets China 6 emission standards when purchasing: The salesperson will provide a vehicle acceptance form during the purchase, which includes the model, color, emission standard, engine number, and chassis number. A China 6 compliant car is one that meets the national sixth-stage motor vehicle pollutant emission standards. Compared to the China 5 standard, the China 6 emission standard has lower emission limits. The early implementation of the China 6 emission standard will reduce carbon monoxide, hydrocarbons, non-methane total hydrocarbons, and nitrogen oxide emissions by approximately 50% for light-duty gasoline vehicles compared to the China 5 stage, and particulate matter emissions by about 40%. Automotive emissions refer to harmful gases such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) discharged from vehicle exhaust, all of which are harmful gases produced during the engine combustion process.
I just bought a new car not long ago, and I paid special attention to the China 6 label when purchasing. Asking the 4S store salesperson directly was the most convenient. They showed me the vehicle's environmental protection label on the spot, which was stuck in the corner of the front windshield, clearly marked with "China 6b". The new car certificate also included details about the emission standards, and they even had me scan the VIN code with a mobile app to check the official records. For used cars, I checked the production date section in the vehicle registration certificate—cars produced after 2019 are most likely China 6 compliant. Driving a China 6 car is more environmentally friendly, with lower emissions and slightly better fuel efficiency. It never hurts to pay attention to government subsidies. Don’t think it’s troublesome—taking a few minutes to check can prevent you from buying a non-compliant vehicle. Safe driving is what truly matters.
As someone who works with engines all day, I'm quite familiar with the China 6 emission standards: when you open the hood of a new car, the emission information on the nameplate clearly states 'CN6' or 'China 6'. You can also confirm compliance by checking the OBD port with a diagnostic tool to read the parameters. Extra caution is needed for used cars - for example, using the Traffic Management 12123 APP to input the VIN and check historical records. The China 6 standard includes upgraded particulate filters, so regular cleaning of the filtration system during routine maintenance is crucial to avoid clogging and performance issues. Always verify this before purchasing a car - it ensures long-term peace of mind and environmental friendliness.
