What symbols represent China 5 and China 6?
2 Answers
China 5 and China 6 are represented by English symbols, with China V and China VI denoting China 5 and China 6 respectively. The China 6 standard is an upgraded version of the current China 5 standard, imposing stricter limits on the emission of CO, THC, NMHC, NOX, and PM compared to China 5, while also introducing new regulations on PN emissions. According to the China 6 emission standards, light gasoline vehicles will see a reduction of approximately 50% in carbon monoxide, hydrocarbons, non-methane total hydrocarbons, and nitrogen oxide emissions compared to the China 5 phase, with particulate matter emissions reduced by about 40%. For heavy-duty diesel vehicles, nitrogen oxides and particulate matter will be reduced by more than 60% compared to the China 5 phase.
China 5 and China 6 are different phase symbols of China's automotive emission standards. China 5 represents the fifth-phase emission requirements, targeting new vehicles around 2017 with relatively lenient limits, mainly controlling carbon monoxide and hydrocarbon emissions. China 6 upgrades to the sixth phase, implemented from 2019, divided into China 6a and China 6b, with the b phase being the strictest, reducing nitrogen oxide and particulate matter emission limits by approximately 50% and requiring real driving tests. If you understand cars like I do, you'll notice that China 6 vehicles are more technologically advanced, requiring GPF (Gasoline Particulate Filter) or engine optimization, which reduces pollution but may also increase costs. Overall, knowing this can help you choose more environmentally friendly and reliable vehicles, especially in large cities where it might affect road access convenience.
