9th Fuel Injector

[TDickerson]

I am trying very hard to justify my next year purchase of a new Dodge Ram 3500. Why is Dodge insisting on dumping fuel in the cylinders for the DPF and NOX regenerations. It appears this is causing cylinder wash out and high fuel dilution in the oil. Govt Motors is using a 9th injector in the exhaust system to take care of this problem. Seems we now have 3 different systems between GM, Ford, and Dodge. What is this a Betamax Vs VHS war to see which system is the best. What the heck is going on. To me the duramax makes the most sense. I can't believe what I am hearing and reading about these new polution systems. I really want a new Dodge, but unless they change their system I am going to have to go with the duramax. At least the fuel is being sent to the exhaust sytem and not down the cylinders. I am still reading up and trying to get more educated on this whole process. Oo.

It is odd eh? For the most part it may be too early to have full results, but it does appear the Cummins exhaust stroke style is doing OK. There has not been massive motor failures etc and logevity seems to still be there.



On the other hand, I do agree. Anything with fuel in the oil, the life blood of your motor, has to be bad!! Also that raw fuel goes through the turbo!



In the end, you know you would not be happy with a Duralax and you know it! Guess we will have to see what Dodge/Cummins does in the new model. My guess, is to date this has been the simplest and most cost effective way of doing it. Look at the cost of a new Duralax and Powerjokes. They are much more costly than a Cummins and way more complex. This could be part of the reason... .

BSchwarzli, you are so right. I think alot has to do with the cost of research and development. Why not use what is already in place vs adding new stuff. But, my confidence with this system just isn't there. It would probably take a while for any real damage to happen with fuel dilution, and we would probably be past the warranty period. That concerns me though. Once the warranty is over we might have some real issues. Sounds like a gamble I'm too old to deal with at this point. Thanks for your honest reply.
