Diesel engines — NOx reduction agent AUS 32 — Part 5: Refilling interface for passenger cars

ISO 22241-5:2012 applies to diesel engine powered road vehicles using selective catalytic reduction (SCR) technology. It is primarily intended for use by passenger cars and light commercial vehicles including buses with a gross vehicle mass of not more than 3.5 t, but may also be used by vehicles with a gross vehicle mass of over 3,5 t.

ISO 22241-5:2012 specifies the refilling interface for the NO_X reduction agent AUS 32 in compliance with ISO 22241-1, which is needed to operate converters with the selective catalytic reduction (SCR) exhaust treatment system. It specifies the essential functional and geometric requirements of the refilling system in order to ensure compatibility between the on-board refilling system and the off-board refilling system.
