What does National VI mean?

[OBrady]

National VI refers to the China VI emission standard, which is the automotive emission standard implemented in China. It strictly controls the emission limits of pollutants. Under the exclusion of working conditions and test influences, the carbon monoxide emissions of gasoline vehicles are reduced by 50%, the total hydrocarbon and non-methane hydrocarbon emission limits are decreased by 50%, and the nitrogen oxide emission limits are tightened by 42%. Methods to check the emission standard of a vehicle: 1. Look at the fuel consumption label on the new car; 2. Check the new car's nameplate, find the vehicle model number (a combination of numbers and letters), and take a photo with your phone; 3. Find the engine model number of the new car; 4. Visit the Motor Vehicle Environmental Protection Website, input the vehicle model and engine model to query.

Speaking of China VI, it's the latest generation of vehicle emission standards, officially known as the China 6 Emission Standard. Simply put, it aims to make vehicle emissions cleaner by reducing particulate matter and carbon monoxide. I recall that in China, China VI was gradually implemented starting from 2019, being much stricter than the previous China 5 standard. It requires upgraded engine technologies in new vehicles, such as installing particulate filters or optimizing fuel systems, to reduce harmful substances in exhaust gases. For us car owners, when buying a new car, we need to check the environmental label on the windshield to confirm if it meets China VI standards. Otherwise, driving into restricted zones in cities like Beijing, Shanghai, Guangzhou, or Shenzhen could get you stopped. I often hear friends say that maintaining a China VI-compliant car requires extra attention to fuel quality—using poor-quality fuel can easily clog the filters. Overall, this standard pushes the automotive industry toward greener development, making the air cleaner.

As a seasoned driver, I have a deep understanding of the impact of China VI on our daily lives. For instance, when buying a new car, you must ensure it's a China VI model; otherwise, the resale value of a used car will drop significantly, especially in big cities where China V cars are hardly sellable. Checking a car's emission standard is straightforward—just look at the category listed on the vehicle license or registration certificate. In terms of maintenance, China VI vehicles have higher requirements; you need to choose high-quality engine oil and fuel, and regularly clean the emission system to prevent malfunctions. I remember last year when I helped a neighbor with a China VI hybrid car, we found that if maintenance was neglected for a long time, the warning light would alert you to emission issues. I recommend that when choosing a car, you should inquire more about the model year—cars manufactured after 2020 are generally China VI compliant, saving you trouble down the road.

From an environmental perspective, the China VI standard is truly significant as it directly reduces vehicle emissions, cutting pollutants like nitrogen oxides and particulate matter by nearly half. I often drive to mountainous areas, and when I see clear blue skies and white clouds, I think about how promoting China VI helps protect the environment and reduce smog. Specifically, the new standard mandates automakers to optimize engine technology and adopt cleaner combustion methods. As car owners, what we can do is use China VI-compliant fuel, conduct regular emission checks, and consider upgrading if our vehicles are older. Simply checking the emission label to confirm the compliance level is sufficient.

Looking back at the origin of China VI, it is a crucial part of China's automotive emission policies. I recall that China V was fully implemented in 2017, while China VI was rolled out in phases starting in 2019, with the goal of promoting green transportation. In terms of policy, local governments impose strict penalties on non-China VI vehicles in restricted zones, incentivizing owners to switch to eco-friendly models. This posed significant challenges for manufacturers, requiring them to develop new technologies. As an observer, I believe this policy has led to noticeable improvements in air quality.
