Euro 6 Emission Standards?

[SanLaura]

Euro 6 standards are equivalent to China's National 6a emission standards. Below are relevant details: Limits: In terms of limit values, the National 6A phase limits are slightly stricter than the Euro 6 emission standard limits but more lenient than the U.S. Tier 3 emission standard requirements. The National 6B standard limits are roughly equivalent to the 2020 fleet average limits specified in the U.S. Tier 3 emission standards, making the National 6 standard one of the strictest emission standards in the world. Requirements: As an upgraded version of the National 5 standard, National 6 introduces enhanced environmental requirements across multiple dimensions. The National 6 emission standard is implemented in two phases: starting from July 1, 2020, all sold and registered light-duty vehicles must comply with National 6A limit requirements; from July 1, 2023, they must meet National 6B limit requirements. Framework: While Euro 6 standards are equivalent to National 6a, the National 6 standard framework retains the European standard system but also incorporates advanced practices from U.S. standards, such as evaporative emissions, fuel emissions, and onboard diagnostics system regulations.
