Diesel engines - NOx reduction agent AUS 32 - Part 1: Quality requirements
|Publication Date:||1 February 2019|
|ICS Code (Fuel systems):||43.060.40|
This document specifies the quality characteristics of the NOx reduction agent AUS 32 (aqueous urea solution) which is needed to operate selective catalytic reduction (SCR) converter systems in motor vehicles with diesel engines. SCR converter systems are particularly suitable for selectively reducing the nitrogen oxide (NOx) emissions of diesel engines.
