How are China VI-A and China VI-B certificates marked on FAW medium trucks?
2 Answers
Vehicle certificates do not indicate whether the vehicle complies with China VI-A or China VI-B standards. Here are the specific details: 1. Two phases: China VI-A and VI-B represent two implementation phases of the national China VI emission standard, with different effective dates. China VI-A was implemented from July 1, 2019 to July 1, 2021, while China VI-B runs from July 1, 2021 to July 1, 2023. 2. Release timeline: The China VI emission standard was announced on June 28, 2018 as the implementation method for the sixth-stage vehicle pollutant emission standard. Pilot implementation began on July 1, 2019 for heavy-duty diesel and fuel-powered vehicles, while light-duty vehicle standards took effect on the same date. Nationwide implementation for all vehicles occurred by July 1, 2021. 3. Carbon monoxide emissions: China VI-A requires 30% lower CO emissions than China V, while China VI-B mandates an additional 20% reduction from VI-A levels. Compared to China V, hydrocarbons and nitrogen oxides are reduced by 50%, and particulate matter by 30%. China VI-A serves as a transitional phase, with China VI-B representing the full implementation standard.
I've just researched this issue. The conformity certificates for FAW medium-duty trucks are quite standardized in labeling China VI-A and China VI-B. They are usually indicated at the top of the vehicle parameter sheet page, using standard abbreviations like 'China Ⅵa' for China VI-A and 'China Ⅵb' for China VI-B. There's a significant gap between these two standards, with China VI-B having stricter requirements, especially regarding particulate emissions, so the labeling distinction is crucial. When purchasing a vehicle, I personally checked the certificate, which also includes detailed emission codes like GVW and other parameters to ensure no conflicts during registration. I remind everyone to carefully inspect this section when taking delivery to avoid being misled and affecting registration. As an established brand, FAW's certificates are quite reliable, but extra caution is needed to avoid counterfeit documents during second-hand transactions. Most newly released truck models now comply with China VI-B, while older models might still be mixed in, so it's important to ask dealers for specific details when selecting.
