What does the China 6 standard refer to?

[SanGriffin]

China 6 standard is actually a regulation for controlling exhaust emissions from motor vehicles. Below is a detailed introduction about it: 1. China implemented the first phase standard in 2001, and currently China 6 is the sixth phase emission standard. The formulation of China 6 standard is based on China's national conditions, while integrating both European and American standards, and no longer distinguishes between gasoline and diesel vehicles. This means that China 6 standard will surpass Euro 6 and become one of the most stringent exhaust emission standards in the world; 2. The China 6 standard aims to prevent environmental pollution caused by exhaust from compression ignition and gas fuel ignition engines, improve air quality, and set limits on gaseous and particulate pollutant emissions from heavy-duty engines; 3. At this stage, the goal of China 6 is to set carbon monoxide emissions within an appropriate range, first reaching 700mg/km, and then achieving 500mg/km.
