What is the Chinese equivalent of Euro III emission standards?

[McKiara]

Euro III standards are equivalent to China's National III standards. Relevant information is as follows: 1. Euro III: Under Euro III emission standards, the limits for hydrocarbons, carbon monoxide, nitrogen oxides, and particulate matter in commercial vehicle exhaust are 0.66%, 2.1%, 5%, and 0.1% respectively. 2. National III: China's National III standard represents the third phase of China's vehicle emission standards, which is equivalent to Euro III emission standards. This means the tailpipe pollutant levels match those of Euro III, with the key difference being that new vehicles must be equipped with an OBD (On-Board Diagnostics) system.
