It’s a popular misconception that Cummins is owned by car companies such as Ford or Chrysler. Cummins Turbo Technologies, in fact, is a separate firm that designs, manufactures, and sells a whole range of diesel and natural gas engines.
Does Ford own the Cummins engine?
This is a rather prevalent myth for a variety of reasons. The fact that Ford was once a minority shareholder in Cummins’ shares, or that Cummins had previously provided engines to Ford, could lead to the conclusion that Ford owns Cummins. For many years, you could get a brand new Ford with a Cummins diesel engine fitted from the manufacturer if you were looking for one of the company’s F650/F750 medium duty trucks.
For several years, Ford offered Cummins diesels alongside the Power Stroke and even a Caterpillar option in their medium-duty platforms. In reality, the 6.7L Cummins Turbodiesel was the only diesel engine offered in the F650/F750 from 2011 to 2015. (Ford did not initially offer their own 6.7L Power Stroke). Are you ready for a surprise? Allison transmissions are available in the F650 and F750 versions as well!
Where are Cummins diesel engines made?
Cummins produces diesel engines with displacements greater than 70 liters, therefore anything below the Class 5 truck market is considered “light duty” by them. The current High Output and standard 6.7-liter ISB inline-six oil burners in Ram’s 2500/3500 heavy-duty pickups and 3500/4500/5500 chassis cabs, on the other hand, are designed for medium-duty use. They’re built immediately south of Cummins’ international headquarters in Columbus, Indiana, at the Columbus Midrange Engine Plant (CMEP). We came to observe where this well-known truck engine is made.
In 1971, CMEP began manufacturing pistons, connecting rods, pulleys, rocker housings, and water pumps on a site covering more than 400 acres. It closed in 1988 to adapt to engine manufacture, restarted in 1991, and has since been feeding Dodge/Ram assembly lines. Other chassis makers have used CMEP, but their production pales in comparison to Dodge’s, and the plant should be producing engine No. 2 million soon. A total of 587,904 square feet of manufacturing and office space is available.
CMEP is easy to discover by car or even by air, as it is located just off Interstate 65. The roof of the factory, which also serves as a 500-space parking lot, is crimson. Sealing the roof is a routine maintenance item because it expands and shrinks up to 16 inches in temperature extremes.
Who owns Duramax?
DMAX Ltd. is a joint venture between General Motors and Isuzu Diesel Services of America, Inc., with GM owning 60% and Isuzu Diesel Services owning 40%. Its plant manufactures the Duramax 6.6L V-8 turbo-diesel engine found in GMC Sierra and Chevrolet Silverado HD pickup trucks.
Does Caterpillar use Cummins engines?
Caterpillar Inc., which lost its hegemony in heavy-duty engines last year due to problems with 2007-compliant models, has announced that it will exit the North American Class 8 market by 2010, with the exception of a severe-duty truck and engine developed in collaboration with Navistar International Corp.
As most truck manufacturers have opted to prioritize proprietary engines, the Caterpillar decision leaves Cummins Inc. as the only independent heavy-engine manufacturer in North America.
In a conference call with reporters on June 12, Caterpillar’s director of global on-highway products, George Taylor, said, “In North America, we see a ceiling of between 240,000 and 250,000 heavy trucks, and it will become increasingly difficult to compete as an independent engine manufacturer.”
Caterpillar and Navistar also announced a partnership to sell trucks and engines around the world, with an initial focus on China, Western Europe, Russia, Poland, and Australia.
“In the 2010 time range, we hope to produce a severe-duty truck focused at construction, logging, oil fields, and low-boy,” Taylor added. Both the truck and the engine will be built by Navistar, though they will be separate entities “Taylor said both will be “reconfigured” to Cat specs and will carry the Cat brand.
“For the trucks, I like the color yellow,” he said, alluding to Caterpillar’s usual machinery color.
Caterpillar will continue to sell Class 8 power plants until 2009, according to Taylor, and will continue to support the estimated 1.6 million Caterpillars on the road in North America “For the rest of those engines’ lives.”
Through an agreement with German manufacturer MAN AG, Navistar, the nation’s leading maker of medium-duty diesel engines, will begin building its first heavy-duty variants, branded MaxxForce engines, this summer.
Paccar Inc., the only other U.S. truck manufacturer without a unique engine, will begin marketing its own brand in 2009. Paccar, which owns Kenworth Truck and Peterbilt Motors, will start producing Class 8 engines in North America based on models from its European DAF operation.
Daimler Trucks North America, which manufactures Freightliner, Sterling, and Western Star trucks, is a division of Daimler AG, which also manufactures Detroit Diesel and Mercedes-Benz engines.
In North America, Volvo AB of Sweden supplies its own engines for Volvo and Mack trucks.
Caterpillar had dominated the heavy-duty truck engine market for the previous decade until Cummins overtook it last year, a trend that continued in 2008.
In 2007, all engine manufacturers were required to provide new technology to comply with stricter federal pollution regulations, but Caterpillar’s engines were plagued by claims of frequent breakdowns and poor performance (11-12, p. 5).
According to R. L. Polk & Co., Southfield, Mich., Caterpillar was the market leader in Class 8 engines in 2006, with 81,335 new engines registered in the US, accounting for 29.8% of the total, and Cummins 67,463, accounting for 24.7 percent.
With the total truck market down considerably in 2007, Cummins had 52,800 new engines registered, accounting for 30.9 percent of the market, while Caterpillar had 43,907, accounting for 25.7 percent, according to Polk.
Navistar’s chairman and chief executive officer, Daniel Ustian, told reporters that the company took the decision in North America because “With only a 10% market share, we haven’t been a strong player in severe service, but this arrangement allows us to get into that market.”
According to Ustian, the severe-duty industry generates 15,000 to 18,000 new vehicles per year “and we anticipate receiving a sizable portion of it.”
Within six months, the two corporations hope to finalize a definitive agreement on their global alliance.
International’s Class 8 customers have typically chosen Cummins engines roughly 75% of the time, with Caterpillar engines spec’d 25% of the time, according to Ustian.
In 2010, International, Peterbilt, and Kenworth indicated they will continue to offer Cummins engines, though the 15-liter type will be the only Cummins model available on International trucks. MaxxForce units will be required for 11-liter and 13-liter engines, according to Ustian.
According to him, Navistar’s deal with Cummins is only good until 2013, and “After that, “one possibility” was for Navistar to develop its own 15-liter engine.
Volvo spokesman James McNamara stated that the company does not sell Caterpillar engines and does not comment on other firms’ behavior.
“We’ve been anticipating something like this for several years,” Paccar treasurer Robin Easton told TT. “We plan to sell Caterpillar engines for as long as they are manufactured, after which we will offer clients the option of choosing between our Paccar engines or Cummins, with whom we have a 60-year connection.”
Even when it dominated the market, Caterpillar had problems with on-highway engines.
The Environmental Protection Agency fined Caterpillar $128 million for engines it sold in late 2002 and 2003 that did not meet new EPA pollution limits (1-12-2004, p. 27).
Caterpillar received EPA certification for their ACERT technology in the same year, which it said was different from the exhaust gas recirculation technology used by all other manufacturers.
One of the important points of their agreement, according to both Navistar and Caterpillar, is that they both rejected selective catalytic reduction technology in order to meet 2010 U.S. and Canadian nitrogen oxide emission reduction regulations. They’ve also chosen not to use SCR in any other countries.
To meet the 2010 mandates, Cummins will utilize EGR, while Daimler, Volvo, and Paccar will use SCR, which has been used in select European trucks since 2004.
Is a Duramax better than a Cummins?
Torque is the most important factor in hauling, but horsepower isn’t far behind. Whether you’re towing or not, more horsepower means faster acceleration. With 445 horsepower, the latest Duramax 6.6L L5P diesel dominates this category. The modern Ram Cummins 6.7L 24V diesel engines have 400 horsepower. Historically, the Duramax line has had a modest horsepower advantage over the Cummins line.
Does Komatsu own Cummins?
Komatsu Ltd. and Cummins Inc. have formed the Komatsu-Cummins Engine Company (KCEC). Komatsu Ltd.’s manufacturing operations and Cummins’ worldwide MidRange engine manufacturing operations both rely on KCEC.
Is Cummins the best diesel engine?
Cummins diesel engines are known all over the world for being exceptional truck engines, not only because they provide the horsepower and torque a work truck requires to carry a heavy load, but also because they are known for their unparalleled durability.
