标准范围

本文件规定了NOx还原剂AUS的加注接口？32符合ISO？22241-1，这是操作具有选择性催化还原（SCR）排气处理系统的转换器所必需的。本文件规定了开放式再填充系统的最低功能和几何要求，以确保车载再填充系统和非车载再填充系统之间的兼容性。密封再灌装系统的兼容性条件见附录？A.本文件适用于ISO？3833且车辆总质量超过3.5？t，设计用于使用固定的非车载加注系统。本文件也适用于固定式非车载再填充系统的喷嘴。笔记？在整个文献中，术语“NOx还原剂AUS？32”缩写为“AUS？32”。

This document specifies the refilling interface for the NOx reduction agent AUS 32 in conformance with ISO 22241-1, which is needed to operate converters with a selective catalytic reduction (SCR) exhaust treatment system.

This document specifies the minimum functional and geometric requirements of an open refilling system, in order to ensure compatibility between the on-board refilling system and the off-board refilling system. Compatibility conditions for a sealed refilling system are provided in Annex A.

This document applies to commercial vehicles and buses as defined in ISO 3833 and having a gross vehicle mass of more than 3,5 t, designed to use stationary off-board refilling systems. This document also applies to the nozzle of stationary off-board refilling systems.

NOTE            Throughout this document, the term “NOx reduction agent AUS 32” is abbreviated to “AUS 32”.
