What is the Chinese equivalent of Euro 5?
1 Answers
Euro 5 emission standards are roughly equivalent to China's National 5 emission standards. The differences between Euro 5 and National 5 are as follows: 1. Connection: Euro 5 refers to a higher standard for vehicle exhaust emissions in the European Union. Its standards require HC emissions below 0.1g/km, CO emissions below 1.0g/km, NOx emissions below 0.06g/km, and PM requirements below 0.005g/km. National 5 is China's fifth-stage national vehicle emission standard. After review by relevant departments, the National 5 standard was implemented nationwide starting from January 1, 2017. 2. Details: The Euro IV standard, which came into effect in 2006, allowed a maximum particulate emission of 0.025 g/km and nitrogen oxide emissions of 0.25 g/km. The Euro V standard reduced these two indicators to 0.005 g/km and 0.2 g/km, respectively. The Euro V standard requires diesel sulfur content to be less than approximately 10ppm. The goal of the Euro V standard is to reduce particulate emissions from diesel cars by 80% compared to the current "Euro IV" standard, and nitrogen oxides by 20%; for gasoline cars, nitrogen oxides and hydrocarbon emissions are each reduced by 25%; for vans, particulates are reduced by 90% and nitrogen oxides by 20%. After the implementation of the "Euro V" standard, all new diesel vehicles must be equipped with particulate filters.
