What is the emission symbol for China VI?

[MacRylee]

China VI emission standard, also known as the National Sixth Stage Emission Standard for Motor Vehicle Pollutants, is a standard established to prevent motor vehicle pollution emissions and improve ambient air quality. Below is a partial introduction to the China VI standard: 1. In the China VIa emission standard, the carbon monoxide emission limit for gasoline and diesel vehicles is set at 0.5g per kilometer. China VIa adopts the minimum limits of the China V standard, while China VIb represents the true China VI emission standard, with stricter control over nitrogen oxide emissions. 2. The China VI emission standard is an upgraded version of the current China V emission standard. It imposes more stringent limits on emissions of CO (carbon monoxide), THC (total hydrocarbons), NMHC (non-methane hydrocarbons), NOX (nitrogen oxides), and PM (particulate matter mass) compared to the China V standard. Additionally, it introduces new regulations on PN (particulate matter number) emissions.

When I bought the car, I specifically asked the salesperson, and it turns out that China VI (National 6) vehicles no longer have those stickers on the windshield, as the paper-based environmental protection label was abolished long ago. The most important thing is to check the vehicle documents: the vehicle conformity certificate will clearly state 'China VI,' and the first page of the environmental information vehicle list will show the emission standard level. My current car has an electronic annual inspection label, but the paper annual inspection label I previously received from the DMV had a small line of text in the bottom right corner indicating the emission level—China VI vehicles display the GB18352.6-2016 standard. If you lose the documents, don’t panic; you can also find the emission standard at the very bottom of the vehicle license copy or on the second page of the registration certificate. Remember, China VI is further divided into Phase a and Phase b, so make sure to check the specific standard when buying a car to avoid affecting registration.

A friend who works in the environmental protection department told me that China VI vehicles are mainly identified in three ways: First, the VIN code label under the windshield at the factory can be scanned to check emission data on the environmental protection platform; second, the nameplate in the engine compartment, like the one on my car, is engraved with 'Complies with China VI b Standard'; and finally, official channel verification, such as entering the license plate or chassis number on the Motor Vehicle Environmental Protection Website, where the result will display 'China VI'. Friends who bought cars in the past two years should check carefully, as only vehicles produced after July 2019 are mandatory China VI compliant. This is especially important for vehicles being transferred from other regions, as some areas do not allow the transfer of China V vehicles at all.

The mechanic taught me practical methods: open the hood to find the engine model sticker, some models directly print the China VI logo; the most reliable way is to scan the QR code on the vehicle's environmental protection list with your phone, and you can see the officially certified emission standard. Remember to check the nameplates of the three-way catalytic converter and the particulate filter during the vehicle inspection, as China VI vehicles have specific certification codes for these two components. Item 45 of the Vehicle Conformity Certificate also clearly indicates the emission level, so remember to take photos as evidence when buying a car.
