What Kind of Cars Are China 6 Vehicles?
2 Answers
China 6 vehicles are those that meet the requirements of the "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China 6)". The main differences between China 5 and China 6 vehicles are as follows: Different Labels: The simplest and most direct method is to check the vehicle's environmental label, which clearly indicates the standard at the back. For new cars, you can also check the vehicle's factory certificate or log in to the Motor Vehicle Environmental Protection Website and enter the vehicle's VIN number and the last 6 digits of the engine number to query. Different Emission Standards: The China 6 emission standard is the sixth stage of national motor vehicle pollutant emission standards. The China 5 standard, or "National 5 Standard", has an emission control level equivalent to the European Euro 5 emission standard currently in effect.
To understand the China 6 vehicles, I'll explain from an automotive engineering perspective. It's actually the abbreviation for China's National Stage 6 Emission Standard, which imposes particularly stringent requirements on vehicle exhaust emissions, primarily controlling pollutants like PM (particulate matter) and NOx (nitrogen oxides). China 6 is divided into two phases: China 6a and China 6b, with the latter being more rigorous. Testing includes WLTC (Worldwide Harmonized Light Vehicles Test Cycle) real-world driving simulation to ensure compliance under various driving conditions. Automakers employ high-tech solutions like three-way catalytic converters and Diesel Particulate Filters (DPF) to meet these standards. In short, only vehicles that pass the Ministry of Ecology and Environment's certification tests and obtain compliance certificates before leaving the factory qualify as China 6 vehicles. When buying a new car, checking the Certificate of Conformity is crucial—it's not just about environmental protection but also affects vehicle registration and usage convenience. With rapid policy advancement nowadays, not understanding this standard might lead to choosing the wrong car or facing restrictions. Therefore, as a car owner, I always stay updated with relevant information to avoid pitfalls.
