This proposal amends UN Regulation No. 115 to list conditions, especially with regard to retrofit systems, to be met by indirect and direct injection vehicles to be considered as belonging to the same vehicle family. Gasoline direct injection vehicles which operate in indirect gas injection mode should be listed in the same family as indirect gasoline injection vehicles, as the applied gas injection technology is the same and provided that at least one such vehicle is tested as parent vehicle according to the requirements of this Regulation.

Proposal to allow an alternative test method to “set the charge air cooler outlet temperature during bench test to temperature which was observed by vehicle test and corrected to the reference temperature specified in paragraph 5.2.1.” of Annex 5. This alternative method is well recognized in SAE J1349.
