What is the equivalent of Euro III in Chinese national standards?
2 Answers
Automobile Euro III is equivalent to China's National III emission standard. Below is an introduction to the National III emission standard: 1. The National III standard is China's third-stage vehicle emission standard. The National III emission standard is equivalent to the Euro III emission standard, with tailpipe pollutant levels matching those of Euro III. The difference is that new vehicles must be equipped with an OBD (On-Board Diagnostics) system. 2. The On-Board Diagnostics system features an increased number of detection points and detection systems. Oxygen sensors are installed at both the inlet and outlet of the three-way catalytic converter, ensuring compliance through real-time monitoring of vehicle emissions, thereby better guaranteeing the enforcement of the Euro III emission standard. 3. When vehicle emissions fail to meet the Euro III standard due to factors like fuel quality, implementing the National III standard will increase the cost per vehicle. To stably meet the National III emission standard, vehicles must be equipped with technical measures to achieve National III pollutant emission levels, along with the use of fuel that meets the Euro III standard. 4. There is not much difference between National III and Euro III; they are essentially equivalent with only minor adjustments in certain aspects. In China, tailpipe emissions are measured in segments, specifically at 2540 and 5040 states, whereas abroad, emissions are measured under different engine operating conditions and instantaneous states.
As a car owner who frequently researches vehicle emissions, I can tell you that the Euro 3 emission standard is roughly equivalent to our country's China 3 standard. Why do I say that? Because European standards were established earlier, with Euro 3 being implemented around 2000, mainly controlling harmful gases like carbon dioxide and nitrogen oxides. Our country didn't introduce the China 3 standard until 2007, also to address environmental pollution issues, largely modeled after the European framework. I remember when I drove older cars, if there were traffic restriction policies, both China 3 and Euro 3 vehicles were restricted in the same areas, indicating their requirements were similar. Actually, aligning emission standards helps car owners easily handle environmental labels when choosing vehicles or during annual inspections. I recommend paying attention to your vehicle's environmental sticker regularly to avoid fines for non-compliance. In summary, older vehicles meeting Euro 3 or China 3 standards have relatively high pollution levels, so switching to new energy vehicles earlier is more environmentally friendly and cost-effective.
