What is the emission standard for cars from 2014?

[VonJordan]

14-year-old cars comply with either China IV or China V emission standards. Emission standards refer to regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. Methods to check a car's emission standard include: 1. Review the vehicle conformity certificate, which is provided upon the car's delivery and clearly states the emission standard; 2. Check the vehicle's accompanying documents, where the emission standard can be found in the vehicle information section; 3. Examine the conformity of production certificate, which includes exhaust emissions and indicates the corresponding emission standard; 4. Visit the official website of the Vehicle Emission Control Center, locate the public query platform at the bottom of the homepage, enter the vehicle's VIN code and the last six digits of the engine number to retrieve the information; 5. Inspect the vehicle's environmental protection label, where the emission standard is clearly marked on the back of the label affixed to the car's front windshield.
