What is the Chinese equivalent of Euro 4 emission standards?
2 Answers
Euro 4 emission standards are equivalent to China's National IV standards. Below are specific details about Euro 4: 1. In terms of emission standards, Euro 4 is similar to China's National IV, but Euro 4 is more stringent than National IV. 2. The Euro 4 standard refers to the Euro 4 emission standard, which was implemented at the end of 2005 as an important automotive exhaust emission standard currently adopted by most countries. 3. China's National IV emission standard represents the fourth phase of national standards for motor vehicle pollutant emissions. The main automotive emission pollutants include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter).
Since I started playing with cars in the early 2000s, I've noticed the evolution of emission standards. The Euro 4 standard is the fourth stage of European vehicle emissions, equivalent to China's National IV emission standard, basically the same level of pollution control, both implemented around 2005. At that time, cars began to be equipped with better catalytic converters to reduce harmful substances in exhaust, such as carbon monoxide and nitrogen oxides, which were significantly reduced. Currently, National IV vehicles can still be driven, but in big cities like Beijing and Shanghai, they may encounter traffic restriction policies, especially during peak hours when they can't enter the city center, which gives many car owners a headache. If you're considering buying a Euro 4 imported car or a used National IV car, it's advisable to first check local environmental regulations and the vehicle's age to avoid future troubles. After all, the maintenance costs of vehicles increase with emission upgrades, so you need to be careful.
