Engine changes for 2005?

[DBoyd]

Has anyone heard of the proposed changes for the Cummins engine for 2005? I've done a couple of searches and haven't turned up any info.

Thanks

Don,



If you were trying to search the TDR forum, that won't turn up much until the search engine has completed its' job. That is about 5-7 days off yet.



On the web, so far, this is all I have found.



1) Cummins training materials, most is about 3 years old based on when ISB, ISC, and ISX engines were released.

2) A Truck Trends review article on the 2004. 5 features

3) a NW Cummins article on a hot new engine design that may provide clues as to where engine design is going.

4) Not quite on topic, but very interesting is:

Cummins Centinel

By Bill Gatliff

Embedded Systems Programming



The Centinel Advanced Oil Management System is an embedded system that extends oil change intervals on electronically controlled diesel engines by periodically removing a small amount of used oil from the engine's crankcase and replacing it with fresh oil. The used oil is sent to the engine's fuel tank, where it is blended with the fuel and burned during normal combustion.

And that about concludes what I came across in 3 different searches.

Like you said, not much yet...

Thanks very much for the information. Very helpful. I had read a Cummins brochure on the Centinel system and I believe about the only maintenance is a filter change as specified by the computer. Amazing stuff!

I am debating on a 2004 or 2005. It takes me about 6 mo to a year to make such big decisions and didn't want to get an engine with the EGR setup.

Thanks again.

DON,

some where I read that we may see a " varible geometry turbo" like what brand "F" uses . which isn't all bad .

that may help with the EGT's when bombed.

I've not heard about anything else, until the low sulfer fuel hits the pumps.

I have EGR on my VW TDI and it sucks .

I took the intercooler out and flushed it , nasty brownish black goo .

there are ways to reroute egr , did it to mine and no engine codes to date (40k) later. But now have to park VW over a piece of cardboard in garage just like my 98 12 valve RAM to catch drops of oil.

Compared to the intercooler flush I'll live parking over paper until the truck and car are "house broke"

Have you seen the setup the new Caterpillars have on them for emission control?? It is amazing, looks like a plumber's nightmare on the side of the engine??? I think they may be running 1 or 2 turbos and taking the exhaust thru a filter and perhaps some kind of cat convertor. A real mess!!!

The only change I know was from an article (I think in 4 Wheeler) that the lift pump will be replaced by an in tank pump. I don't know what the purpose of this would be, and seems like it would be more difficult to replace (if needed). Does anyone have any more info on this and what the purpose is?

The purpose would be two-fold. Cooling for pump, and to make it a pusher eliminating cavitation problems.



Downside of course is more expensive to replace by having to drop the tank.

2005 changes

I recall reading in some forum in addition to the lift pump being relocated to the fuel

tank the throttle position sensor (TPS) would be eliminated. So I assume it will be an

electronic design rather than mechanical.

finally dodge is going modern with the tps. i think it was/is a **** poor idea to have an external mounted tps in the engine compartment, when you can have a direct mounted one on the throttle pedal assembly. my 97 chevy diesel had the throttle pedal mounted one.

this is a correction to my earlier post concerning the EGR on my VW.

The goo that builds up in the intercoller is from the ccv (misty oil).

rerouting that to atmostphere is an easy fix.

The EGR modifacations that they have right now seem to have trouble throwing engine codes, so I have not done anything to the EGR yet.

Sorry for the mix up , I hope nobody was misled

no tps, no kick down cable, no vacume for auto cruise. different solenoid control for off the line improvments...

What solenoid is this? Are you referring to the wastegate controller?
