The Common Rail ISB is in the road.

[Marco]

I went to a Iveco dealer this morning. While I had some conversation with my buddy there, he mentioned that Iveco has presented a new family of engines build by CUMMINS.
( 4 and 6cyl)
Ok, he sez that those engines has been developed by Cummins/New Holland/Iveco.
Take it for what it's worth.

Point is, it's the ISB, with common rail injection! It's already on the road! Too bad
he didn't have a truck to show me.
He will call me as soon as they'll have one.

The 6 cylinder engine is availabel in 3 HP ranges.

179Hp/132KW/570Nm
209Hp/154KW/680Nm
239Hp/176KW/810Nm

The ECM is a Bosch unit. ( Sorry, you know, I like ECM's) #ad

The gears are moved to the back side of the engine.
HEHE, seems that I'll see the engine of the future before you. #ad

Marco,
Wouldn't have a picture so a fella could see what the common rail injection looks like??

Looks like we might have to start buying engines in Italy #ad

I'm told the new engine is significantly quieter and economy has been improved too.

Who cares about that stuff! #ad
How can we BOMB it!!! #ad

In August I requested info on the "common rail injection system" from Cummins. I was e-mailed some information about this new fuel system. It was stated at that time "we do not expect any major changes in the Cummins ISB in the near future, except for the injection pump and injectors, which may be changed from the Bosch system to Cummins own CAPS (Cummins Accumulator Pump System) design. The CAPS system is being adapted to the ISC 8. 3 first and will be phased onto other engine models such as the ISB 5. 9". the response then went on to say the CAPS system is designed to deliver higher injection pressure and complete timing and fuel quantity control independent of engine speed, which would help attain customer demands while meeting EPA requirements.

The CAPS system offers fuel injection rate-shaping and pilot injection capability. These features, in addition to the ability to control injection pressure independent of engine speed result in more complete combustion, providing improvements in fuel economy, starting torque, transient response, cold start-ability, noise, torque curve shape and emissions.

CAPS is controlled by a powerful ECM. The ECM determines desired fuel injection pressure, timing and quantity from engine, vehicle and driver inputs to provide for optimum engine performance under all operating conditons and driver demands.

The CAPS system is designed for reliability. THe main fuel pump consists of fiver major subsystem:
1) GEAR PUMP
2) HIGH-PRESSURE PUMP
3) ACCUMULATOR
4) INJECTION CONTROL VALVE
5) DISTRIBUTION HEAD

This about all I was able to find out on the up-coming fuel system. Can anybody add any more info?

From Cummins response the CAPS system sounds promising, but I'm sure once DC gets ahold of the engine and ECM it will all go down-hill from there. (sorry for being pessimistic, but is seems DC's track record is to take a good Cummins design and de-tune it into a "lesser" of an engine)

It was mentioned the engine will be quieter, anyone know how much? Will the Cummins end up sounding like the wimpy competition?

1tuffram,
Did you find out if the system would be adaptable to the ISB with the VP44? Well, it would probably just be cheaper to buy a new truck, huh?

Sorry Michael, I only inquired for some general info. I'm a 12 valver considering buying a new truck and wanting to find out more about the new and upcoming trucks so I can make a decison on wether to buy the last of a dying breed or wait until the "next generaltion Ram" comes out and hope it is actually better than the current ISB.

You can contact Cummins at: powermaster@cummins.com for detailed questions. (if that address doesn't work try: Power. Master@Cummins.com) There seems to be 2 sightly different addresses listed on the response I printed from Cummins.

Mike,
The pics are in your Mail Box.
HAVAC,
Before you can BOMB a CR ISB you have to get one. #ad

ECM is the answer to your question. #ad

Marco or Mike,

Are you able to post those pictures of the common rail injection for us to see? Anyone have or heard anymore info about this fuel system?

Marco, since the common rail injection is in use over there any chance of you digging up some information or literature and sending it this way?

 

[Marco]

A S A P !

 

[1tuffram]

Bringing this back to the top to see if there has been any new developments in finding out more information.

 

[Mike Vonada]

1tuffram,
I did not recieve the pic's from Marco so can't post anything. Not sure what happened.

 

[Marco]

Sorry, no news yet #ad

I'll keep you updated.
Marco.

 

[Mike Vonada]

Marco, you must be on the net??

 

[1tuffram]

thought I'd roll this one up to the top again. I'm starting to think I'm whipping a dead horse on this one.

A recent post made reference the new engine will a ISBe. Anyone have any info on this? I have e-mailed Cummins twice tring to dig-up a little info on this ISBe, but have not recieved a response. Guess they are going to keep "tight-lipped" on this until a later date. #ad

 

[Marco]

Sorry Mike, I have no newer pics than the ones I've send you some time back.
Could you post those? They're not good but better than nothing.
Marco

Has anyone thought about cam / lifter replacements or gear cover leaks? The engine will have to come out unless they put an access hole in the dash or the cam is made of rubber!
