In an SCR system, the exhaust passes through a DPF or a combination of DPF and DOC first, then doused with a mist of water and urea commonly referred to as diesel exhaust fluid (DEF). The new engines will be launched in January 2015. Iowa, USA. When an SCR engine is turned off, DEF injection also stops, but the DEF pump circulates DEF for up to 10 minutes to cool the DEF injector.

DEF is 65 percent purified water and 35 percent urea (expect slight variances in formulations from manufacturer to manufacturer in the attempt to provide the lowest possible freeze point) and creates a chemical reaction converting the exhaust into water vapor and nitrogen.
