This new engine technology requires a non-toxic water based solution known as Diesel Emission Fluid (DEF).
Selective Catalytic Reduction (SCR) system operates with its own reservoir of DEF.   Engines complying with Euro IV emission limits (3.5g/kWh) run at higher temperatures, reducing diesel consumption.  Toxic NOx emissions are reduced to nitrogen & water.
