How to Identify China 5 and China 6 Emission Standards for Vehicles?
1 Answers
Methods to check whether a vehicle meets China 5 or China 6 emission standards: You can check the vehicle's conformity certificate or the environmental protection information list that comes with the vehicle. Additionally, you can find the vehicle model number on the vehicle's nameplate, then enter this number along with the correct verification code on the Motor Vehicle Environmental Protection Website to query the vehicle's details, including the emission standard. The China 5 emission standard is marked as 'China V', and the China 6 emission standard is marked as 'China VI', both using Roman numerals. The China 6 standard imposes stricter requirements on pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons. When purchasing a new vehicle, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number.
