How to Distinguish Between China 5 and China 6 Emission Standards for Vehicles?
4 Answers
The methods to distinguish between China 5 and China 6 emission standards are as follows: 1. The China 5 emission standard is marked with a "V", while the China 6 emission standard is marked with a "Ⅵ". 2. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number. 3. For used cars, you can check the emission standard by entering the vehicle model number on the environmental protection website. The steps to query the vehicle emission standard on the environmental protection website are as follows: 1. First, you need to know the vehicle model number, which is indicated on the vehicle's nameplate. 2. Visit the official website for motor vehicle environmental protection, enter the model number in the search box along with the correct verification code, and click "Query" to retrieve the vehicle's information, including the emission standard.
To determine whether a car is China 5 or China 6 compliant, I've discovered several practical tricks over the years of playing with cars. The most straightforward method is to open the hood or check the vehicle's side door for the nameplate, which will indicate 'China V' for China 5 or 'China VI' for China 6. You can also look at the color of the environmental sticker on the windshield: yellow represents China 5, while green usually indicates China 6. Decoding the VIN is also reliable—the 10th character is the year code, with cars around 2017 mostly being China 5 and those after 2019 gradually shifting to China 6. Additionally, checking the production date helps, as cars manufactured in the second half of 2019 mostly fall under China 6. In practical use, China 6 emission standards are stricter, so the engine efficiency is higher, and policies like registration or traffic restrictions in big cities are more lenient. This is especially crucial when buying a used car—I always recommend verifying one more step to avoid trouble.
When I first bought a car, I was naive and couldn't tell the difference between China V and China VI emission standards. Now I've learned some simple tricks. Check the environmental protection page in the vehicle registration certificate - it clearly marks the emission standard as "5" or "6". Install an environmental protection app like "National Vehicle Emission Inquiry" on your phone, input your license plate number to check the result. For new cars, salespeople usually explain it clearly. For used cars, look at the sticker on the lower right corner of the windshield: yellow means China V, green usually indicates China VI. Cars manufactured after 2019 are 99% likely to be China VI compliant. A friend of mine once bought a car without checking carefully and couldn't enter the city due to restrictions, wasting a whole day. Driving a China VI car daily feels cleaner with lower pollutant emissions. Remember to use these methods before buying a car - it's safer and more convenient.
After years of car repair, checking China 5 and China 6 standards is basic work. I often use OBD tools to connect to the car's computer and check the data, where the emission standards are clearly displayed. The manual also clearly marks China 5 with a "V" and China 6 with a "VI". The difference is that China 6 catalytic converters are more advanced, with more efficient exhaust treatment, so diagnostics are stricter when faults occur. During maintenance, avoid modifying the exhaust pipe to prevent exceeding standards. It's simple to check; car owners can just look at the vehicle label or annual inspection report.
