As far as the question regarding the Cat 3406 versus the new ACCERT C series, yeah, good luck with all that. Cummins and Detroit went with an EGR engine. Cat decided to just add more fuel and another turbo for higher EGT's and a "more complete fuel" burn, then put on a big campaign about the EGR engines that recirculated exhaust having higher EGT's. I've yet to talk to a new Cat owner who is happy with the new ACCERT engines. Most claim a 25+% loss in mileage, oh, and lots more heat. Then again, recirculating 10-15% of the exhaust creates way more heat than adding another turbo. Mmmmmmkay. Yeah, Cat burned a couple trucks to the ground in the early stages, but by that time they had too much money tied up not to make it work. :notam:
We have both engines in trucks in our Trucking and Excavation business. I have not noticed the difference in heat you ar talking about in EGT's. The Accert actually runs a lot cooler egt's. Now it does run around 210 degree coolant all day long. That is a lot more heat. We have another new Pete on order. Now we do not watch fuel mileage as we are off road alot and cant get an accurate reading.
