2003 Cummins

[Jff24Gordn]

Just got insider info that Cummins WILL have common rail injection on the next ISB. It will use a 2 squirt setup. A little squirt early to get it burning, and then a big power squirt. No 3rd squirt like the un-duramax. Also, it wont be as high as 300hp, it will be a small hp upgrade. And it wll be alot quieter. There goes the real trucks rattle. And it uses the same basic parts as the un-duramax bosch common rail.

I know most of this has been expected. I just thought I would tell what I herd.

A little bird told me to only look for 275 HP in the new Dodge.

Was hoping for more.

Common rail is correct, it will be much quieter. Booo!

While quieter doesn't set too well with most of us, it will mean more sales for Dodge/Cummins in the overall picture. We'll still have that awesome exhaust note that can't be duplicated by the other two. And the turbo will still sing... And when we raise the hood, it's a beautiful thing!

 

[Don M]

Yeah, a beautiful thing w/EGR!! YUK!!!

Common rail?

At the December Dieselfest last year in Long Beach, the Cummins rep said the 2003 ISB will have EGR and a cat along with the common rail fuel system. Betcha that will be the end of 500 dollar a set injector upgrades and hello to what the Ford guys pay for injector upgrades. At least it will be only six instead of eight.

Hopefully the Cummins rep meant only California models will have EGR and cats. Not that I wish them on y'all but... I thought the B was good for polution control until 2005 without the cat or EGR. I don't hear any complaints about failures. Are the EGR valves a source or trouble or are they just ugly?

 

[Ram4Sam]

From what I remember it wasn't a Calif only situation.

They all get EGR.

The 2003 models might be like the 1998's? Early 2003's without EGR, Jan 2003 and later production with EGR?



Previously on this site the talk was 2004 for the newer restrictions. 2002 for heavier trucks and 2004 for pickups. Maybe they mean motorhomes, the Dodge 4500 and 5500 will have EGR for the 2003 model year?

This is all very similar to what I had heard from some Cummins' PM I spent a few lunches with at a HEV seminar.



The tougher US diesel emmision standards are driving them todo a lot they don't want todo.

It's not just a CA thing.



They warned that the ISB will become more and more choked out with emmisions fix'ins.

As most of you know, the rest of the planet has been enjoying diesel-powered cars, vans and trucks for years as a result of $4. 00+/gallon gasoline prices. During the last decade, diesel technology has exploded into a world of quiet, smokeless, turbo charged rocket sleds! While in Yurrup on vacation, I had two different rental cars, both diesel... . both were screamers!... I dont mean fast for diesel... I mean fast for a Corvette! My 5-door Alfa would run about 140mph and get there in a huge hurry, without even sounding, smelling or feeling like a 'diesel'. This car was electronically controlled, common-rail with all the pollution stuff in place. If this is the direction our trucks are taking, I welcome it with open arms.

This exact subject was discussed at that US/Canada HEV conference.



In "Yurrup" since fuel prices are soo high, diesel is cheaper than gas,, and the diesel cars are more fuel efficient. Despite the noise and such, they embraced the diesel years ago. As BCFAST pointed out they've enjoyed a ton of development time and their is a ton of diesel technology there.



For HEV applications, (it's widely accepted in the industry) that diesels are more easily tune to run more efficent than a gas engine at a single or small RPM ranges.

Efficient not only meaning fuel usage, but emmisions as well.



The US has not accepted the diesel in past for reasons we're all probably formiliar with... price of gas, avilibility of diesel in the past, noise , smoke, VW rabbit, Chevy V8 diesel conversion...

All pasting negative diesel emotions in the mass publics head.



Since the diesel engine is the choice for the HEV designer. And the fact that "yurrup" wants diesels and US (& Japan, but they are kinda split) wants gas, the big three are dragging their heels on real HEV designs. They've finally targeted the SUV market since thats their #1 profit platform. The military is already there, they have mandated the use of diesel - no gas, and all new designs are diesel based, even the HEV vehicels they are bringing into the field soon. You will being seeing some of the most radical 4X4's around soon from the military that will make the Hummer look useless.



Oh well, after re-reading that post not sure if it's worth much... but I'll leave it anyway incase someone may find it interesting...
