Message: [QUOTE="Dzchey21, post: 1124939, member: 63"] Your right fuel dilution is down a great amount from 6.4s... the injectors are much more advanced and do a much better job of delivering the fuel where it needs to be in the exhaust Disagree with part of this, Its not exactly the same. Once you add in An SCR you have effectivily changed the entire process. Since NOX is no longer controlled as much by egr you are allowed to run a higher combustion temperature (which is why EGR is there To lower the combustion temp to lower NOx) THe higher temperatures allow for more ash and soot burn off in a natural "passive" regen state. This requires less fuel to be injected into the engine to do a regen. I agree and dissagree at the same time. With the addition of SCR and urea egr usage is reduced by 80%, HINCE the reason the egr cooler is now smaller because there is less going into the engine. These engines have proven to go over 350k miles in bone stock form with very little issues. I can't beleive i am saying this but i agree with you.. FORD spent a ton of money to refine this process to help save the engines. Fuel economy is better, HP is up, EGR usage is down NOx is down, and regen time and frequency is down. Win win for people who cant tune or don't want to tune and really all around for anyone. I wouldnt be scared to own a DPF on truck for the long haul. Only thing that sucks is when a sensor goes down it pretty much limps you. [/QUOTE]
