How to Write China 6?

[SanKinsley]

The correct way to write China 6 is China VI, using Roman numerals. The China 6 emission standard is divided into two phases: China 6a and China 6b. China 6a will be officially implemented in 2020, and China 6b will be officially implemented in 2023. The following is an introduction to the China 6 emission standard: 1. The 'National Sixth Stage Emission Standards for Motor Vehicle Pollutants' includes two parts: 'Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)' and 'Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI)'. 2. China 6 is formulated to implement the 'Environmental Protection Law of the People's Republic of China' and the 'Air Pollution Prevention and Control Law of the People's Republic of China', to prevent pollution of the environment by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, to protect the ecological environment, and to safeguard human health.

I work at an auto repair shop and have to write this every day. 'China VI' must be written as 'China National Stage VI Motor Vehicle Pollutant Emission Standards,' as it's printed on invoices and certificates. Customers often ask why it's not the Chinese character '六' (six). Actually, the regulation requires using uppercase Roman numerals like 'V' and 'VI' to differentiate, such as China V and China VI. Last year, a car owner got stuck during the annual inspection because the modification shop wrote 'China 6' on the form incorrectly. Now, the new vehicle registration system only recognizes formats like 'VI'—getting it wrong can cause major delays.

Selling used cars has taught me that adding a space when writing 'China VI' is the most standard format. Just look at the vehicle license, it's always printed as 'China VI', and the environmental label stickers follow the same format. I once saw a recycled car with its registration certificate stating 'China 6', and the DMV required a new proof to be issued. Emission standards are not something to be careless about—getting it wrong could affect the transfer of ownership, especially in cross-province transactions. When buying new energy vehicles, also pay attention; hybrid versions must clearly indicate they meet the China VI standard.

Driving school veteran tells you: Roman numerals must be used when writing China 6. Look at the annual inspection sticker on our coach car's windshield - it's printed with 'China VI' in black on a yellow background. When replacing the car last year, the DMV specifically emphasized that the purchase tax declaration form would need to be refilled if written as 'China 6'. It's even more crucial to write it correctly when selling used cars, as second-hand car platforms all recognize the VI identifier for emission filtering. Remember that the full version is 'China National Stage VI', but the abbreviated form is sufficient for daily paperwork.
