Here are the specific methods to check which national emission standard a vehicle complies with: 1. Check the vehicle's environmental protection label, which typically has clear markings on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center for inquiry. 3. Bring the original or a copy of the vehicle registration certificate to the local vehicle management office for query. 4. For new vehicles, check the factory-issued vehicle compliance certificate, which is usually kept at the vehicle management office. It is advisable to make a copy for backup when purchasing a car. 5. Make a rough estimation based on the vehicle's registration year. Most vehicles registered after 2008 comply with China IV standard. Vehicles registered in 2007 may be China III or China IV, while those registered before 2007 are mostly China III or China II. Vehicles registered before 2005 are predominantly China II standard.

As a seasoned driver with years of experience, the most straightforward way to determine a car's emission standard (e.g., China 5 or China 6) is to check the vehicle registration certificate. That big green booklet clearly states the emission level, as it's officially mandated information. I always verify this when purchasing a car to ensure accuracy, as it directly impacts urban driving restrictions—in major cities like Beijing, Shanghai, Guangzhou, and Shenzhen, vehicles below China 5 may be barred from central areas. If the document is lost, you can apply for a replacement at the traffic management department or use the 'Motor Vehicle Environmental Protection Inquiry' app by entering the license plate number for a free check—it's incredibly convenient. Additionally, the environmental sticker on the windshield sometimes displays emission details; pay attention during routine maintenance and ask the mechanic to verify it. Don’t overlook these details to avoid fines or reduced resale value. In short, official documents are the simplest and most reliable source.

As an environmental enthusiast, I'm accustomed to using mobile apps to check vehicle emission standards. The 'Motor Vehicle Environmental Protection Network' mini-program developed by national authorities is particularly useful. Simply input the license plate number and engine number, and it displays the emission standard, such as China III or China IV, completely free and instant. This method is more reliable than guessing based on the year or model. My friend always uses it when buying used cars to avoid high-pollution vehicles. Emission standards directly impact air quality, and urban policies like traffic restrictions are based on them. Generally, China V and above are acceptable. I also recommend asking sellers when purchasing a car—dealership salespeople usually know the emission level of new cars. If unsure, getting an environmental test at an inspection station is an option, with reasonable fees. Understanding these details aids daily car use, reduces environmental impact, and these tips can be shared on community platforms.

I often buy used cars, and experience tells me the quickest way is to check the manufacturing year. National emission standards are implemented in phases by year. For example, cars produced after 2017 generally meet China V standards at minimum, while those after 2020 mostly comply with China VI. I can roughly estimate this by checking the policy timeline online. However, this isn't 100% accurate, so I always verify with the vehicle conformity certificate or registration documents. I remember my first purchase when I didn't know better - the seller claimed it was China III but it turned out to be an older standard, almost got scammed. Now I always insist on checking documents or using the VIN to verify official data online, simple yet practical. Emission levels significantly impact resale value - China I vehicles depreciate fast and face stricter restrictions in limited zones, so it's worth careful consideration before buying.

Is Dongfeng Nissan the same as Nisan?

Exactly the same, Nisan and Nissan are different Chinese translations for the same car manufacturer NISSAN; Nissan is the official name and trademark of the Japanese Nissan Motor Company, written in Roman letters as NISSAN, while Nisan is a phonetic translation of NISSAN. In fact, it was originally called "Nisan", but due to trademark registration issues, when NISSAN officially entered China, it was found that a company had already registered the name "Nisan", so it had to change from a phonetic translation to a combination of meaning and phonetic translation as "Nissan". More related information is as follows: Note 1: NI actually means "day" in Japanese, such as Nippon for Japan; "san" is phonetically translated from SSAN, so NISSAN adopted the new name "Nissan". Similar cases of forced name changes due to intellectual property issues include LEXUS changing from "Lingzhi" to "Lexus", and ROVER's "Land Rover" changing to "Land Rover". Note 2: Nissan (NISSAN) is a Japanese automobile manufacturer founded by Aikawa Yoshisuke in 1933 in Yokohama, Kanagawa Prefecture. Currently, it has automobile manufacturing bases in 20 countries and regions (including Japan) and provides products and services in more than 160 countries and regions worldwide.
