Hello all

I am puzzled as to why SCR uses Adblue solution which is only 33% Urea. Why not use 100% Urea minimise fill ups and weight?

Thanks

Becuase it's ammonia that is needed, not urea. You don't have enough water floating round to react in time. So you are injecting both reactants.

Stupid question really Urea is a solid. It's solubility in water is 107.9 g/100 ml @ 20 °C. Presumably 33% at -10C or something.
