What emission standard does China VI correspond to?
1 Answers
China VI is equivalent to the China 6 emission standard. Here is relevant information: 1. Currently, China divides the "China 6 emission standard" into two phases - "China 6a" and "China 6b", with nationwide implementation planned for 2020 and 2023 respectively. The China 6 standard, officially named "National Stage 6 Motor Vehicle Pollutant Emission Standard", was established to implement environmental protection laws, aiming to reduce and prevent vehicle exhaust pollution, protect the ecological environment, and ensure human health. 2. Compared with China 5, the China 6 standard reduces nitrogen oxides by 77% and particulate matter by 67%, introduces limits on particle number (PN), and adds requirements for emission control device durability and on-board diagnostic systems (OBD).
