What is the Chinese equivalent of Euro 4 emission standards?
3 Answers
Euro 4 emission standards are equivalent to China's National 4 emission standards. Below is relevant information about Euro 4 emissions: 1. In terms of emission standards, Euro 4 is similar to China's National 4, but Euro 4 is stricter than National 4. It can be said that Euro 4 is more advanced than National 4. Given current technology, emission standards are unlikely to be upgraded within the next decade or so. Upgrading emission standards must consider not only technology but, more importantly, cost factors. 2. China's National 3 and National 4 emission standards for light-duty vehicles have identical pollutant emission limits to Euro 3 and Euro 4 standards. The Euro IV standard refers to the Euro IV emission standard, which was implemented at the end of 2005 as an important standard for automotive exhaust emissions and is currently enforced in most countries. This standard requires that diesel passenger cars emit no more than 250 milligrams of nitrogen oxides per kilometer; vans and SUVs must not exceed 390 milligrams of nitrogen oxides per kilometer.
Through my years of research on emission standards, I've found that Europe's Euro 4 is actually quite similar to China's National 4 standard. When formulating the national standards, we referenced the European system, with many limit requirements being basically identical. However, the timelines don't quite match up - Europe started implementing Euro 4 in 2003, while China didn't introduce National 4 until 2011. This correspondence is particularly important for car purchases, especially in the used car market for European-standard imported vehicles. When you see a Euro 4 badge, you know it can basically be treated as equivalent to National 4. Some cities' traffic restriction policies are also based on National 4 standards, so if you're driving a Euro 4 vehicle, you generally won't be affected. Of course, there might be slight differences in actual test data due to varying road conditions and fuel quality, but overall these two standards represent the same tier of environmental requirements.
I remember studying this specifically when changing cars a decade ago. The Euro 4 emission standard set in Europe corresponds to China's National 4 level. The principle is quite simple - the emission limits for pollutants are similar, with basically equivalent control requirements for harmful substances like carbon monoxide and hydrocarbons in exhaust gases. Nowadays, when you see imported older cars with Euro 4 labels on the road, such as Audis or BMWs from around 2009, applying the National 4 standard would be accurate. One thing to note is that testing might be a bit troublesome, as inspection stations still follow domestic standards, but the actual data generally matches up. Currently, National 4 vehicles face elimination pressure in many cities, and Euro 4 cars are in a similar situation. You need to carefully consider policy risks when buying such vehicles.
