That's a nifty little slide show, looks like what MANY here have been asking for.

Except that it is a cast iron block with aluminum heads!



Guess Cummins is waiting to see how the DuraMax holds up before introduction.

Except too the V6 like the V8s won't have that low end torque the inline 6 has now. Try this on a powerchoke or maxipad V8 with a MANUAL transmission and you'll find out quickly why the Cummins is so good.



Put the transmission in second, keep your accelerator foot on the seat next to you and let out on the clutch. Phord will die. I don't think the Chevvy will do any better except I haven't tried the Allison transmission yet. Try it on a Dodge and you will take off in 2nd, 3rd and 4th gears on a stock truck.



While towing my 33 ft fiver with GCWR at the max 20,000 pounds I can move the unit, uphill (6%grade), without pushing the throttle. What more can a diesel freak ask for?

Because the Cummins has a governed idle speed...

Cool

Hope they offer this in a JEEP Liberty or Wrangler. :--)

It don't figure??????????

From what I have read, Cummins use to make a V8 long ago, then dumped it due to problems and stuck with the in-line design. They already have a in-line 4 cylinder (ISB), why not use that instead of developing something entirely new ... especially a V-design with ALUMINUM heads running at high RPMs!



Bad decision by Cummins.

Aren't all diesel engines governed?

 

[DT]

All diesel engines have a governed max rpm, but not a minimum governed rpm.



btw billr: where in junction do you live? I'm out here in fruita...

That's easy. Look at the hood of your truck. Pretty long isn't it? They can fit a V-6 without intruding any more into the cab or making the front end (and wheelbase with it) longer to accomodate an inline engine.



Also, if they can get 30MPG from this diesel engine in the Durango and the same (most likely more) power and torque as a V-8 gasser small block or big block , why would that ever be a bad idea?



I think it's a great idea from Cummins and Chrysler. If they had done this with the '02 Durango I would have bought one on the spot instead of the Ram. Don't get me wrong, I love my truck, but it would have been more practical for me to get an SUV for the baby and all the crap I have to carry now. I also wouldn't have to buy a camper shell of bed cover for security of the stroller and other assorted baby stuff. Plus I would have a diesel, 30MPG, and all the HP and torque I would need to pull my boat and TT. Just my humble/honest opinion.

ISB 3.9 4-CYL

MBERRY,



I can't see the ISB 3. 9L 4-cyl taking up anymore room that the current V8 in the Durango. I'm sure it could be updated to produce the HP and tourque required and Cummins could save all that R&D money ... and I'm sure that the 3. 9L would get close to if not better than 30mph in a 1/2 ton or Durango.



Boy, I don't know why Cummins would want to reinvent the wheel, and I'm sure that they could sell DC on the ISB 3. 9L



Well, I guess thats why a programmer and not a Captain of industry.

Size and configuration sells. Look at all the Powerstrokes that sold, there were a lot of them that sold because it was the biggest diesel available. There are a lot pf people that are not going to buy an inline 4 when a V6 is available. We have had gutless I4's for too long.



I agree with MBerry that it would suit my purposes just fine, probably better than my current truck. Ford will have just such a thing out soon, probably late this year or very early next year. If the V6 powerstroke hits its targeted numbers it will be very interesting.

and besides, a V-6 should vibrate a whole lot less than the 4

here is a pic of a cummins triple nickel in my work truck

its rated at 250 hp, the tag is tore up and i cant reasd the torque.



it sounds really wicked.

governed idle rpm

It has been posted that a Cummins can be started in 3rd and 4th without killing the motor... . Mine will die right off the bat. . If what you are saying is correct, do I have a problem. If so what should I look for. My truck is a '97 3500 4wd.



Thanks

 

[maint.man]

We've got a Grove crane that has a good ol' triple nickel cummins in it . I'll have to admit , until I opened the side sheilds I thought it was a Detroit .

Is that a Phram oil filter?

Texram - starting in 3rd & 4th

Texram - trying to take off in 3rd or 4th will kill the engine if you engage the clutch the same way as when using the throttle. You have to slip the clutch a little - sort of ease the engine into the load. Doesn't do the clutch much good.



When showing off, I like to start in 2nd and shift up thru the gears without touching the throttle.



There's no substitute for the low end torque. Let the ps and dmax leave me behind when the light turns green and cruising the interstate. I'll catch and pass them on the hills.
