What are the symbols for China 5 and China 6?

[XavierFitz]

China 5 and China 6 are represented by English symbols, with China V and China VI denoting China 5 and China 6 respectively. The differences between China 5 and China 6 are as follows: Emission Limits: The China 6 standard imposes approximately 40% to 50% stricter emission limits compared to China 5. The emission levels under China 6 are significantly lower than those of China 5. Simply upgrading engine technology as before to meet emission standards is unrealistic. Achieving China 6 requirements necessitates comprehensive optimization approaches, such as integrated improvements (or additions) including the engine, PDF, particulate filters, and other components. Fuel Neutrality: China 6 adopts the principle of fuel neutrality, meaning that regardless of the fuel type used, the emission limits remain the same. In contrast, during the China 5 phase, diesel and gasoline vehicles had different emission standards. Emission Standards: Compared to China 5, the China 6 standard reduces nitrogen oxides by 77% and particulate matter by 67%. It introduces limits on particulate number (PN) and imposes stricter requirements on the durability of emission control devices and On-Board Diagnostics (OBD) systems.

I was just looking into the China 5 and China 6 symbols the other day—those stickers labeled as 'China V' or 'China VI' that are pasted on the corner of the windshield or under the hood, like a small tag. China 5 is the older standard, still used by many older cars, with higher exhaust emissions. China 6 is the upgraded version, with stricter pollution controls, and almost all recent cars follow this standard. It’s especially useful when buying a used car—my friend had to sell his car cheaply because it was China V and couldn’t enter the downtown restricted zones. You can find this symbol on the environmental label or vehicle certificate—just a quick glance can tell you whether it’s the old or new standard, and it can even help save on fuel costs. Remember, China 6 cars are cleaner, more eco-friendly for long-term driving, and cost-effective—don’t overlook this small detail.

After paying attention to environmental protection for a long time, the China V and China VI symbols seem like progress stamps to me: China V represents the old emission level, which is slightly more polluting; while China VI is the new symbol, with cleaner exhaust and better air quality. These symbols are usually printed near the car logo or on certificates, making them easy to identify. Promoting higher standards can help cities reduce smog, so when buying a car, I prioritize those with the China VI mark to encourage green travel. These small symbols carry great significance, and collective action leads to a healthier life.
