What is the China III Emission Standard?

[HaydenLee]

National Emission Standard Stage III is the abbreviation. Below is a partial introduction to the China III Emission Standard: 1. Introduction: The China III Emission Standard is equivalent to the Euro III emission standard, with the content of tailpipe pollutants matching that of Euro III. The key difference is that new vehicles must be equipped with an OBD (On-Board Diagnostics) system. 2. Considerations: For motor vehicle pollutant emissions to stably meet the China III standard, vehicles must be equipped with technical measures that ensure emissions comply with the China III standard, while also using fuel that meets the Euro III standard. 3. About OBD: OBD stands for On-Board Diagnostics. The system features an increased number of detection points and enhanced detection systems, with oxygen sensors installed at both the inlet and outlet of the three-way catalytic converter. It ensures compliance by continuously monitoring vehicle emissions in real-time, thereby better guaranteeing the enforcement of the Euro III emission standard.
