How to Distinguish Between China 5 and China 6 Vehicle Emission Standards?
4 Answers
The differences between China 5 and China 6 are as follows: 1. Different carbon monoxide emission requirements: China 5 allows 1000 milligrams per kilometer; China 6 allows 500 milligrams per kilometer. 2. Different particulate matter emission requirements: China 5 allows 5 milligrams; China 6 allows 3 milligrams. 3. Different nitrogen oxide emission requirements: China 5 allows 60 milligrams; China 6 allows 35 milligrams. 4. Different non-methane hydrocarbon emission requirements: China 5 allows 68 milligrams; China 6 allows 35 milligrams.
To distinguish between China 5 and China 6 vehicles, as a car enthusiast who frequently researches cars, I mainly rely on a few simple steps. First, check the vehicle nameplate, which is located near the engine compartment or the passenger door frame, marked with 'China V' or 'China VI'—China VI being the latest standard. Second, examine the environmental compliance certificate; the documents provided when purchasing the car will clearly state the standard. If buying a used car, check the emission information on the registration certificate, which can be found online by entering the vehicle identification number (VIN). From the manufacturing year, most cars produced after 2019 are China 6, while those before are likely China 5. China 6 vehicles have stricter pollution control measures, emit cleaner exhaust, and contribute to better urban air quality. When I bought my own car, I used these methods, which indeed made the process much easier. Nowadays, some major cities have imposed restrictions on China 5 vehicles, so choosing a China 6 car is more convenient for future use and also retains higher resale value. I often follow automotive forums where many people share practical tips, such as using apps to scan QR codes and check standards. In short, these small tricks make car selection simpler and more environmentally friendly.
From an environmental perspective, the key to distinguishing between China 5 and China 6 standards lies in the emission details. I pay attention to the vehicle's environmental label, usually located in the corner of the windshield or on the compliance certificate, which clearly states 'China V' or 'China VI'. The China 6 standard is more stringent, requiring a reduction of over 50% in carbon monoxide and nitrogen oxide emissions, which greatly benefits urban environments. The manufacturing year is also a straightforward indicator, as vehicles produced after 2020 are mostly China 6 compliant, avoiding pollution issues. When purchasing a car, I would recommend prioritizing China 6 models because they comply with more green policies and are not subject to driving restrictions. In daily use, China 6 vehicles are more fuel-efficient, have lower carbon emissions, and are beneficial for long-term health. I've noticed that some auto shows display environmental data to help consumers understand the differences. Promoting China 6 can also drive technological innovation, such as electric vehicle auxiliary technologies. In summary, choosing China 6 is a great way for individuals to contribute to environmental protection and is worth promoting.
As a young person buying a car, I'm used to checking the small labels on the vehicle to determine if it meets China 5 or China 6 emission standards. Just look for the environmental label on the windshield or open the hood to check the nameplate – 'China VI' indicates the newer China 6 standard. The manufacturing year helps a lot too; cars made after 2019 mostly comply with China 6, while older models might be China 5. When purchasing, the salesperson will provide the manual which clearly states the standard. Nowadays, car apps make it convenient – just enter the VIN code to check. China 6 vehicles emit fewer pollutants, giving you more freedom on the road without restrictions in some cities. Last time I chose a China 6 car – it wasn't expensive and felt more futuristic. I can also share some user experience, like how smart the air conditioning adjustment is. In short, these little tricks make car buying simple and efficient.
