How to Distinguish Emission Standards for Sedans?
2 Answers
You can check the vehicle emission standards through the following methods: 1. Look at the label sticker behind the vehicle's environmental protection qualification mark to easily view the emission standard; 2. The vehicle certification mark starts with this page, which includes an emission standard description, but it is not directly written as National Standard X. Instead, it is a string of characters. You can then search online for the meaning of this string; 3. You can estimate the vehicle's emission standard based on its model year or verify it by bringing the vehicle registration certificate to the local vehicle management office. Here is additional information: According to the new regulations issued by the Ministry of Environmental Protection, starting from July 1, 2020, all newly sold and registered vehicles must comply with the China 6a standard; from July 1, 2023, all newly sold and registered vehicles must comply with the China 6b standard.
I researched emission standards when buying a used car last year. The most straightforward way is to check the vehicle's production year: most cars from 2008-2012 are China IV, 2013-2016 are generally China V, and post-2017 are mostly China VI. But the most accurate method is to check the "Motor Vehicle Environmental Protection Information List" - it's labeled on the nameplate in the co-pilot door frame or engine compartment. Nowadays, WeChat mini-programs can also check it - just enter the VIN and it'll display immediately. Here's a lesser-known fact: gasoline cars produced after July 2019 must comply with China VI-b standards, with structural differences in the GPF (Gasoline Particulate Filter) inside the exhaust pipe. China III vehicles are basically restricted in Beijing, Shanghai, Guangzhou, and Shenzhen - especially avoid them when buying used cars, otherwise you won't even be able to get license plates.
