How to Distinguish Between China IV and China V Vehicle Standards?
2 Answers
Methods to distinguish between China IV and China V vehicle standards: 1. Check the vehicle's fuel consumption label; 2. Look at the vehicle's nameplate to find the vehicle model number (a combination of numbers and letters) and the engine model number, then log in to the Motor Vehicle Environmental Protection Website, enter the vehicle model number and engine model number to query. The China IV emission standard is the fourth stage of national standards for motor vehicle pollutant emissions. Vehicle emission pollutants mainly include hydrocarbons, nitrogen oxides, carbon monoxide, particulate matter, etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, these standards control and reduce vehicle emissions to below specified levels.
The simplest way to distinguish whether a car meets China 4 or China 5 emission standards is to check the environmental label or vehicle conformity certificate that comes with the car. These documents are usually provided at the time of purchase. The environmental label is either affixed to the corner of the windshield or kept in the document folder, clearly marked as 'China IV' for China 4 or 'China V' for China 5. If you've misplaced these documents, don't worry—just call the 4S dealership or the local vehicle management office. They can look up the information using your license plate number. Remember, China 5 standards became mandatory in 2017, so cars manufactured after 2017 are generally China 5 compliant, while older models might still be China 4. This distinction is crucial for annual inspections and urban driving restrictions. In major cities like Beijing and Shanghai, China 4 vehicles are banned from city centers, and violations can result in fines. Always insist on seeing the official documentation when buying a car—never rely on verbal assurances from the seller. Otherwise, you might encounter issues during ownership transfer, which could significantly impact resale value. With over a decade of experience in the used car market, I've seen many people regret not verifying these details. Spending a little time and money to confirm can save you from major headaches down the road.
