How to Distinguish Between China 4 and China 5 Vehicles?
2 Answers
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.
