I stand corrected if this is the exact way urea is used in the 11's.
"The newest, approach is selective catalytic reduction using urea DEF. The urea-based solution (32.5 percent industrial urea and 67.5 percent deionized water) is held in a separate storage tank and injected as a fine mist into the hot exhaust gases. The heat turns the urea into ammonia that - when combined with a special catalytic converter - breaks down the NOx into harmless nitrogen gas and water vapor."
However, if I understand it correctly, in order to burn this, the truck has to burn more fuel to create this process? AM I WRONG,,, CHEROKEE?!?!!? This is the reason these trucks are still getting less mileage than they should!?!?! Isn't this why owners still delete the DPF and get a tune???? To get better mileage??? So, maybe I was slightly off on my statement, "urea is used to burn the black soot" when it should have said, "it's injected as a fine mist into the hot exhaust gases, that get hot by increasing the trucks RPM's by burning more fuel, but who knows,,, maybe I'm still wrong!! PLEASE CLARIFY!!!! There's no need to be rude ,, CHEROKEE!!!
If I'm still wrong, help me out.
