Differences Between China 6 and China 5 Standards

[McLaila]

China 6 adopts the fuel-neutral principle, meaning that regardless of the fuel type used, the emission limits remain the same. In contrast, during the previous "China 5" phase, diesel and gasoline vehicles had different emission standards. Compared to China 5, the China 6 standard reduces nitrogen oxides (NOx) by 77% and particulate matter (PM) by 67%. Other relevant information: China 5 standard refers to the National Phase 5 Motor Vehicle Pollutant Emission Standard, also known as "China 5 Standard." The emission control level of China 5 is equivalent to the Euro 5 emission standard currently implemented in Europe. The European Union has been enforcing this standard since 2009, imposing stricter limits on motor vehicle pollutants such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. From China 1 to China 4, each upgrade in the standard reduced single-vehicle pollution by 30% to 50%.
