What is the equivalent of Euro III in Chinese national standards?
4 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.
As a mechanic who frequently tinkers with cars, Euro 3 is essentially equivalent to China 3. You see, the emission limits set by Euro 3 for engines, such as particulate matter and sulfur content, are almost identical to those of China 3. Nowadays, when repairing cars, if we come across older models labeled Euro 3, we usually classify them under China 3 after checking the standard values with a diagnostic tool. Of course, while China's standards are modeled after Europe's, they aren't exactly the same. Euro 3 was introduced in 2000, whereas China 3 wasn't officially rolled out until around 2007, leaving a time gap in between. When car owners ask about this, they might be concerned about vehicle inspections or urban driving restrictions. I've worked on many cars, and those meeting Euro 3 or China 3 standards tend to have exhaust systems that age quickly, requiring regular maintenance. Always remember to check the vehicle manual or the environmental compliance certificate to avoid issues at the DMV. In any case, ensuring the emission standards match will make driving more worry-free and safer.
I know many people are curious about which China emission standard Euro 3 corresponds to. Simply put, it's equivalent to China III standards. European emissions were divided into stages, and Euro 3 played a crucial role in reducing pollution in the early days. China later introduced China III around 2007, with standards similar to Euro 3 levels. This isn't just about matching numbers - the regulatory requirements and testing methods were aligned. I think understanding this is useful for car owners, such as when evaluating vehicle age for emission testing. Don't underestimate this - environmental agencies enforce strict checks, and mismatches can cause problems. Maintaining your vehicle to meet emission standards is always the best approach.
