What is the Chinese equivalent of Euro IV emission standards?
2 Answers
Euro IV emission standards are equivalent to China's National IV emission standards. In terms of emission standards, Euro 4 and National 4 are similar, but Euro 4 is stricter than National 4. It can be said that Euro 4 is more advanced than National 4. As of July 1, 2019, some cities in China have implemented the National VI emission standard, which references both the Euro 6c standard and the North American EPA-Tier3 standard requirements for OBD and evaporative emissions, hence being referred to as the 'strictest global standard.' Below are detailed explanations: 1. Implementation Time: The Euro IV standard refers to the Euro IV emission standard, which was implemented at the end of 2005 and is an important standard for vehicle exhaust emissions, currently enforced in most countries. 2. Standard Requirements: This standard stipulates that diesel cars must not exceed 250 milligrams of nitrogen oxides per kilometer; vans and SUVs must not exceed 390 milligrams of nitrogen oxides per kilometer. The National IV emission standard is China's fourth-phase motor vehicle pollutant emission standard, with main pollutants including HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter).
As an ordinary person who drives frequently, I have some basic knowledge about emission standards. Euro IV refers to the European Stage IV emission standard, which corresponds to China's National IV standard, as it is commonly called. I remember it was introduced in Europe around 2005, and China officially mandated the National IV standard for new vehicles in 2009. This is crucial when buying used cars; National IV vehicles have lower emissions, pass annual inspections more easily, and are more environmentally friendly and reliable compared to older National III models. A friend bought an imported Peugeot two years ago labeled as Euro IV, and it was registered as a National IV vehicle without any issues. Understanding this can save you money—many cities allow National IV vehicles to enter urban areas during traffic restrictions. Just avoid overloading or tampering with the exhaust system in daily driving, and the emissions will remain compliant. European and Chinese standards are roughly equivalent, though there might be minor differences in details, but overall, it doesn’t affect usage.
