Cummins to Produce High-Performance, Light-Duty Diesel Engines for Automaker
26 July 2006

Cummins Inc. has reached agreement with a major automotive manufacturer serving the North American market to produce and market a light-duty, diesel-powered engine. For competitive reasons, Cummins’ original equipment manufacturer partner in the venture has asked to remain confidential.
As part of the agreement, Cummins will develop and manufacture a family of high-performance, light-duty diesel engines for a variety of automotive applications in vehicles below 8,500 pounds gross vehicle weight, including standard pickup trucks and sport utility vehicles. Certain bus, marine and industrial applications also will be served by this engine family.
The first vehicles with this engine are expected to be ready for market by the end of the decade. Cummins anticipates that this diesel engine will provide an average of 30% fuel savings, depending on the drive cycle, over gasoline-powered engines for comparable vehicles.
The concept for this product is the result of a nine-year partnership between Cummins and the US Department of Energy that has been developing an engine family with a 4.2-liter V6 and a 5.6-liter diesel V8 that will meet EPA Tier II and CARB LEV II emissions standards.

In test vehicles, development versions of the 4.2-liter V6 have delivered combined cycle fuel economy of 22.1 mpg US, while development versions of the 5.6-liter V8 delivered 21.7 mpg US.
Earlier work on the new engine family used precise control of the air handling system and combustion to reduce engine-out emissions, followed by aftertreatment with a four-way catalyst system, including NOx Adsorber and Particulate Filter.
This agreement gives the driving public an even greater opportunity to experience the benefits of a new class of vehicles powered by a high-performance, fuel-efficient, clean diesel engine made by Cummins. This line of diesel engines also will fuel the growth of an exciting new market in which Cummins does not currently participate.
—Tim Solso, Cummins Chairman and CEO
Cummins currently provides on-road engines for the Dodge RAM pickup and a variety of medium- and heavy-duty vehicles, as well as off-highway and marine engines.

Now if only they could manufacture a 1.5-2.0 liter 4-cylender like this and we'd be good to go.

I would like to see a turbo-charged, two-cylinder, opposed 1.0 liter, to be used to drive a generator only.
It would be fueled by alcohol enhanced BioDiesel.
Only when needed, it would start up and recharge the Li-Ion battery pack.

Clean emissions is particularly difficult on diesels when used in start/stop operations like listed above because their inherently lower exhaust gas temperatures mean more smog-forming emissions when the catalyst is below operating temperature. It's a tough battle between smog emissions and GHG emissions. Die locally of asthema illnesses, or die globally from potential global warming?

I imagine this will be the engine used with the Nissan HD Titan. I know they were looking into cummins to power the Titan, and I think will probably be the engine that does it.
Posted by: Mike | July 26, 2006 at 04:04 PM
I believe that Dodge uses Cummins Diesels in some of its pick-ups.
Posted by: Robert Schwartz | July 26, 2006 at 05:12 PM
The Titan sounds like it is going with Navistar. The big Cummins plant is in Columbus IN. Honda is moving to Greensburg-20 mins. away. Poss. a connection!

Chrysler would be smart to use the V6 for the LX platform (Magnum, Charger, 300). Many here in deepest Alabama would pay a premium to own a diesel car that's not a Volkswagen or a heavy duty truck.

As to diesel engines' NOX and particulate problems, is it possible to strip N2 out of the intake gas? You may have to compensate with recirculaated gas, but it may enable hotter and cleaner operation.
Posted by: allen Z | July 27, 2006 at 07:01 AM
allen Z, it is *possible* to strip the N2 out of the atmosphere coming in but not cost effective nor practical by any means.

John Ard - in europe you can get the Chrysler 300 with a 3.0 merc v6 diesel. I'm thinking about getting one for me next car.

Darn you Europeans! :)

Is there a chance this engine will be utilized by Ford? I know Ford is developing their own diesels in England to be used here eventually, but might they also be teaming up with Cummings for the sheer volume needed for future demand and to have greater product flexibility? One thing for sure, Ford wants to get away from international permanently.
Posted by: John | July 27, 2006 at 05:43 PM
Why even bother wit this? Haveya been next to a Sprinter idling? 5cyls rule.
Posted by: fred | July 28, 2006 at 03:07 AM
why you would tool up, in this day and age, to build a motor that has no system to produce power from its waste heat is beyond me.

Need infos on biodiesel buses and trucks
Posted by: Leon Danchet | July 30, 2006 at 10:43 PM
My 2004 Dodge 2500 is a Cummins Diesel, averages 20mpg while often towing a horse trailer, and I have only ever used Biodiesel in it. I now have 18k miles on it in two years with zero problems. All biodiesel courtesy of Biofueloasis.com in berkeley, ca. [other car is a 2000 honda insight]
Posted by: rob | July 31, 2006 at 02:36 PM
Come on! dodge chrysler is hooked up with Mercedes benze right? There fore why not pay your sister company or yourself to develop diesel engines like the ones in Mercedes NoW...for dodge chyrsler cars and trucks...they can in house everything instead of outsourcing. Cummins and dodge will not be a synonym in the near future. Maybe that honda plant 20 miles away is using cummins plant in INDIANA in a strategic way.huh.....

Honda will not need Cummins.
Honda is already in a "Technology Exchange" with GM for a diesel engine from the Isuzu. The deal is: GM gets to use Honda's 3.5 L V6 engine and tranny for the Saturn Vue Red-line and Honda gets to use the Isuzu diesel engine for future vehicles and rights to use On-Star in future vehicles.
Posted by: Sven | August 08, 2006 at 07:48 AM
what we ultimatley need is a 1.5L diesel with some form of Mercedes BluTec which will cut the emmisions, and to further extend that. use the heat waste and pressure from the exhasst to push a low resistant generator, whilst having the the motor itself power the electric motor. and for the problem of heat at start up use the electric batteries to heat up the catylst and motor
this would be running on electric about 75% of the time and using the efficent diesel to charge the batteries
75-80MPG right there

There are more effective and practical solutions to the problem, than there is willingness to think forward on the part of the auto companies. They have a vested interest in NOT changing. They think green means money, not environment. What incentive can we give the auto companies' boards to change their priorities?

if somebody has more info from largest vehicle , around 9 tons GVW, please contat with me. I strongly interested over Hybrid drive system.

If Cummins was asking me, I'd be developing a high rpm 4.0L Diesel V8 platform, with MDS (Multiple Displacement Technology) for high end automotive and low end truck/SUV applications.
A 4.0L diesel V8 could spin well over 4,000 RPM for the high end automotive-sports car set, could easily generate 450 Ft Lbs of torque for the 1/2 ton pickup and SUV crowd, and with Hemi-like MDS, ought to be able to shut off 4 cylinders of fuel when not needed and get well over 30 MPG when cruising. And I ask you, who would not want to buy such a vehicle? Gene

Cummins once made a 3.9 liter diesel using the same architecture as the 5.9 liter Dodge Ram engine. Why not use the same components and eliminate a lot of development cost?
This engine would be rated at about 200 HP and could power a 1/2 ton pickup and get 25/30 MPG with the right gearing and a few aerodynamic tweaks.
Posted by: Mike Thayer | August 29, 2006 at 01:31 PM
Anything to the rumor Cummins will build a new plant for this on DCX Chrysler land in Kokomo, Indiana, near the 4 existing Chrysler foundry and transmission plants there?
Posted by: clo | August 30, 2006 at 11:03 AM
My understanding is the V6 will go in Dodge Ram 1500 and possibly Dakotas, Durangos, and hopefully in the larger cars. My dad was in Chicago and was told this by someone in the DC group at a display on Navy Pier.
As for Rob's comment about Cummins and Dodge: Dr. Z isn't stupid. He knows Dodge Diesel and Cummins are synonymous and isn't going to ruin a good market plan. With Ford and International Truck and Engines (ITE), the problem isn't the engine manufacturer, it's FORD. ITE's original design for the 6.0 PowerStroke was a good design, but Ford wanted to cut costs, so corners were cut, at Ford's demand. That's why the first 6.0 PS motor had problems. If I were ITE, I would've said "no deal."
My dad wants one for the farm. Says he doesn't need the B5.9, as he has grain trucks to do his heavy hauling. He just needs a pickup with good fuel economy to make small "pickups" and trips to town from the field.
As for using the B3.9, that would work in the Ram, but it wouldn't exactly fit in a car, height-wise, if you want to keep things streamlined. This is one of the reasons HMMWV motors are V-motors. I-6s are too tall.

i think intelligent individuals need to work some sort of petitions not only to the industries but polititians to to their heads out the sand and start dealing with our environmental problems before it is a last minute problem.
and as to the exhuast output of cars many houses through the coal power plants that supply their electicity pollute far more than cars
Posted by: matthews | September 04, 2006 at 06:58 PM
The Cummins V8 will go into the Dodge Ram 1500, and the V6 will go into the Durango and Dakota. They will both be manufactured at Cummins main plant #1 in Columbus, IN.

Listed below are links to weblogs that reference Cummins to Produce High-Performance, Light-Duty Diesel Engines for Automaker:
They should do a 2.8L 4 cylinder version while they are at it. Then they could use it in smaller SUVs or whatever.
Keep plugging away with diesel - it will be part of the ultimate solution.
