How to Distinguish Between China V and China VI Emission Standards for Cars
2 Answers
Methods to distinguish between China V and China VI emission standards for cars: The China V emission standard is marked with the Roman numeral V, while the China VI emission standard is marked with the Roman numeral VI. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes details such as the model, color, emission standard, engine number, and chassis number. For used cars, you can check the vehicle's full model number on the environmental protection website. Car emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot. China's emission standards differ from European standards; China's standards are national regulations tailored to the country's specific conditions, while European standards are common among European Union member states, with European standards being slightly higher than China's.
I just researched this a couple of days ago when helping a friend check used cars. The most straightforward method is to check the vehicle license - it clearly states the emission standard. New cars' factory certificates also have markings like 'China VI' or 'China V', as clear as an ID card. Many cars have environmental labels on the windshield - just take a look. Checking the manufacturing date is also reliable: gasoline cars after 2017 are mostly China V standard, while those after July 2019 are basically China VI. If still unsure, you can use the Vehicle Identification Number (VIN - that alphanumeric string at the lower left of the windshield) to check on the DMV website or search for mini-programs on WeChat to find registration information.
