No DEF for 2020 Emissions??
Has anyone else heard any rumblings on DEF being eliminated for 2020 emissions? I've heard it from 2 different people, but have NOT seen a thing in any semi web site or on a trucking radio show.

After working on EGR on a diesel; IMHO yes.
EGR is a bad idea when it comes to a diesel engine. Does it work? Well, sort of.........until it causes other problems.........which it will.
The problem is all of these systems are VERY expensive. Very soon a 100K pickup will be the order of business. My LBZ might be the last pickup I ever own if that's the case.- Are downstream emissions likely to be simpler and less troublesome than current emissions systems?
- More than likely the same people that said in 2014 Ford was for sure coming out with a V8 Eboost. :R
Like eHoefler said; downstream is the trend and DEF is part of downstream. - They are eliminating the EGR valve on the Cummins engines in 2019 model year. All emmisions will be downstream in the exhaust, and DEF is going to be part of it.
- I know that they are experimenting with other ways to package DEF, namely cartridges where DEF is served up in another medium that is dry, no liquid. It just has a heater element for cold operation and once up to temp, natural exhaust temps causes the cartridge to naturally release the ammonia. It has promise, and gets rid of the crystallizing issue.
SAE Article - I have not heard that, unfortunately strict emissions on diesels will continue. The next generation of fire trucks being spec out for next year shows the same def systems. I don't see the gov stepping away from this, and the company's that make def won't give up either since it's a money maker.....
