You don't need to treat NOx if you never create it.

Wow...thanks for those links. It really pisses me off that manufacturers [because of mandates by the EPA?] don't go this route. But I guess filling the water injection tank with H2O (or a H2O/CH3OH solution) does little to fuel a separate DEF economy that the EPA (or friends of those in those within) no doubt reap the benefits of.
