What is the Chinese equivalent of Euro 3 emission standards?
2 Answers
Euro 3 is equivalent to China's National 3 emission standard. The Euro 3 standard is an automotive exhaust emission regulation established by the European Union. According to this standard, the limits for hydrocarbons, carbon monoxide, nitrogen oxides, and particulate matter in commercial vehicle emissions are 0.66%, 2.1%, 5%, and 0.1% respectively. As the environmental damage caused by vehicle emissions becomes increasingly severe, countries and regions worldwide have successively established limits for vehicle exhaust emissions. The European standards set by the EU serve as a reference for most countries and regions. Based on the content of these harmful substances and the gradual implementation timeline, European standards are divided into four phases: I, II, III, and IV. Higher numbers indicate stricter standards and relatively lower pollution levels.
Veteran drivers tell you that Euro 3 is basically equivalent to China 3 standards. This label was commonly seen on imported cars around 2003. Nowadays, this standard is completely outdated, and many cities prohibit China 3 vehicles from entering urban areas. Last week, I helped my neighbor with his vehicle inspection—his 2007 Euro 3 Passat almost failed the emissions test because the testing station said the catalytic converter was worn out. In fact, Euro 3 cars can be salvaged by replacing the catalytic converter, but with annual inspections getting stricter, it's more hassle-free to just replace the car. To check your car's emission standard, the most accurate way is to look at the environmental label on the windshield.
