What is Euro 4 equivalent to in China's emission standards?

[LorenzoAnn]

Euro 4 emission standard is equivalent to China's National 4 standard. The Chinese national emission standards and European emission standards are different. China's national standards are formulated based on the specific conditions of China, while the European standards are the common standards adopted by the member states of the European Community. For vehicles that meet the environmental protection standards, the country issues graded emission standard labels, which are divided into two categories: yellow and green, for the purpose of energy-saving and emission-reduction inspections and regular environmental protection checks of vehicles. China's vehicle emission standards include National 1, National 2, National 3, National 4, National 5, and National 6. Compared to the current National 5 standard, the National 6 standard increases the emission requirements by 40% to 50% on the basis of National 5.
