How much longer will Dodge run a regen set up on the Cummins motor? Are they considering going the route of Urea like Ford and GM? I am not sure if I am going to do deletes as I trade out my truck roughly every 2 years, and if Dodge has a better emissions set-up coming in the future, I will just leave mine alone and wait for the new models.

 

Even though they use urea, I believe Ford and GM are still using DPF's and regen as well, with regens occurring a bit less frequently than without urea.

 

I believe Dodge uses Urea on the 4500 and 5500's already. Think I heard that anyway.

 

Ok, was curious as to whether or not regen systems were going to be done away with at all.

 

45 and 5500's use urea. But they still need the DPF. The Urea is used to lower the NOX

 

That's my understanding as well. I think the Urea system does away with the need for cooled EGR system so they typically get a bit better fuel economy.

 

It appears the 2013 2500 and 3500 will have DEF (urea injection).

I could be wrong, but I believe the Dodge had enough credits to make engines for several year past 2010 that were slightly dirtier due to being cleaner in the 2007.5-2010 period.


With the Urea, you still need the DPF and regen's to collect and get rid of particulate. The Urea is for Nox. Basically they run the engine dirty and use after treatment to clean up the particulate and NOx down stream.

Should be interesting to see what delete comes about with Urea.

 

Dodge is meeting the 2010 emissions without DEF, but the mileage issue is most likely why they are going to DEF.

They are not dirtier than the rest, just meeting it differently.

 

Why do they use Urea on cab chassis? (3500-5500)

 

The C&C trucks in 07.5-09 only met 2007 emissions. When Dodge/Cummins went to meet 2010 emissions they thought that the DEF setup would work better in the C&C world based on how the trucks are used.

 

Have you read something reputable that states that? I'm thinking they will do it, but I haven't found anything that says so.

 

H&S has Urea delete kits for the Ferds and Chebys already.

 

Here's pictures. Looks production ready. Rumor is to expect it for 2013.
