How to Distinguish Between China 4 and China 5 Vehicles?

[DeJude]

Distinguishing between China 4 and China 5 vehicles can be done through the following methods: 1. Check the vehicle's fuel consumption label; 2. Check the vehicle's nameplate; 3. Check the environmental protection inspection qualification mark. China 4 and China 5 refer to different stages of emission standards set by the national regulations. The higher the number of the emission standard, the higher the level, and the higher the level, the lower the engine's emissions will be. The differences between China 4 and China 5 are: 1. Different upper limits of sulfur content in gasoline: China 4 stipulates an upper limit of sulfur content in gasoline of 50 milligrams per kilogram; China 5 stipulates an upper limit of sulfur content in gasoline of 10 milligrams per kilogram. 2. Different nitrogen oxide emission standards: China 4 nitrogen oxide emission standard is 0.08 milligrams per cubic meter; China 5 nitrogen oxide emission standard is 0.06 milligrams per cubic meter.

I've always been a car enthusiast, and helping people distinguish between China IV and China V vehicles is quite simple. First, check the vehicle identification plate, usually located on the inside of the hood or the door frame of the passenger side, which indicates the emission standard such as 'China IV' or 'China V'. China V vehicles are generally produced after 2013. The VIN code can also be useful—search online for a VIN query tool, enter the license plate number, and the system will display specific emission data. Don’t forget to check the new vehicle certificate or the duplicate of the vehicle registration certificate, as these clearly state the standard. For used cars, the environmental label is a clue—green or blue labels are mostly China V, while yellow or older labels may indicate China IV. Before purchasing, I’d recommend taking the car to a testing station for a quick check to avoid being scammed. These methods are not difficult and can be done yourself in just five minutes, ensuring a safe and environmentally friendly car choice.

I once got burned buying a used car when the seller claimed it was China V emission standard but it turned out to be China IV. Since then, I've learned some tricks. Check the vehicle's production year - most pre-2013 cars are China IV, while post-2013 models are more likely to be China V. The environmental label on the windshield is also straightforward - a blue label indicates China V, while older yellow labels likely mean China IV. If the sticker is missing, directly check the invoice or original certificate for proof. Using mobile apps like 'Che Guan Yi' to input the license plate and check records is even more convenient. I've tried checking official DMV websites too - free and reliable. Remember, don't just rely on what you hear; verify it yourself to save money and hassle. My friends always appreciate this method during casual chats - simple and effective.

I recommend checking through official channels for the most reliable information. First, log in to the local environmental protection bureau website or the vehicle management office platform, and enter your license plate number to inquire about the emission standard. China V (National 5) vehicles have cleaner emissions, which are better for the environment. Annual inspection records can also help determine the standard. If you don't have a computer, visit the vehicle management office in person with your documents to check the records. Some online mini-programs, such as 'Autohome,' can display results by scanning the QR code on your vehicle registration certificate. These services are either free or low-cost, ensuring accuracy—don't trust unverified claims from second-hand markets.

I believe that China V vehicles cause much less air pollution, so I prioritize checking emissions when selecting a car. Look at the nameplate to see which emission standard it meets, or check the certificate year—post-2013 usually indicates China V standards. Newer green or blue environmental labels often signify China V, while older yellow labels indicate China IV. New vehicle registrations come with a list specifying this. This method saves time—just check it yourself. China V vehicles also often have access to urban restricted zones, offering more driving freedom, and may have slightly lower fuel consumption. Choosing higher emission standards is significantly better for health.

As a used car buyer, I've figured out some identification methods. Check original vehicle documents like purchase invoices and certificates that indicate emission standards. Input the VIN code into online tools to automatically display whether it's China IV or China V. Look for the small metal plate near the engine hood or under the seats. You can also take a test drive to an inspection station for professional emission system checks - China V engines have slightly newer designs, so don't overlook these details.
