Is diesel currently subject to the National IV standard?
Reply #22008-03-04
It has not been implemented nationwide; it is only in use in a few cities such as Beijing.

Has Beijing’s diesel already met the National IV standard? May I ask who has the National IV standard? Could you send me a copy? Thank you!
