Heavy duty trucks just go w/
urea aftertreatment if anything. Treating the entire exhaust stream w/ water is far too weight/volume intensive for a road going vehicle, so what manufacturers do is minimize what NOx emissions they can, use a SCR system to capture the rest, and periodically inject the urea solution into the exhaust stream in order to clean it out. Rinse and repeat. Regarding water recovery, the water has to be deionized, so unless that can be done on the truck, contaminants from the exhaust stream will poison the SCR system.
