Cummins

Cummins Engine Business Unit consists of Aftermarket support, Mid-Range, Heavy-Duty, and High-Power Engines. Cummins manufactures and markets a complete line of diesel and natural gas-powered engines for on-highway and off-highway use. Its markets include heavy-and medium-duty truck, bus, recreational vehicle (RV), light-duty automotive and a number of industrial uses including, construction, mining, marine, oil and gas, railroad and military equipment.[1]

For the general public, the most visible Cummins product may be the 5.9-liter in-line six-cylinder engine used in the Dodge Ram light duty pickups starting in 1988.5.[7] In 2007.5, a 6.7-liter version of the Cummins straight six engine became optional on the RAM pickup.[7] In 2008, Cummins was a named defendant in a class action suit related to 1998-2001 model year Chrysler Dodge Ram trucks, model 2500 or 3500, originally equipped with a Cummins ISB 5.9 liter diesel engine built using a pattern 53 Block.[8] The case has been settled, but some qualified Chrysler owners may receive $500 for repairs to the block, which was alleged to crack and create a coolant leak.

In April 2013, Cummins utilized technology developed by Westport Innovations to begin shipping large natural gas fueled engines to truck manufacturers in the United States as trucking companies began converting portions of their fleets to natural gas and the natural gas distribution network in the United States began to expand.[9]

Cummins has a technical centre in Darlington, England, where it develops products for the European, Middle Eastern, and Asian markets.

The Holset Engineering Co. was a British company that produced turbochargers, primarily for diesel and heavy duty applications.

In 1973 the company was purchased by Cummins after briefly being owned by the Hanson Trust. Holset now operates facilities in China, India, Brazil, the Netherlands, the United Kingdom, and the United States.

In 2006, the division officially changed its name to Cummins Turbo Technologies to be identified more closely with its parent company. The turbocharger products still use the Holset brand name.

In 1990 Cummins began acquisition of Onan and completed it in 1992. Since then, Onan has evolved into Cummins Power Generation (now Cummins Power Systems), a wholly invested division of Cummins. The Onan name continues to be used for modern versions of their traditional engine-driven generators for RV, marine, commercial mobility, home standby, and portable use.

Cummins Inc. (NYSE: CMI) announced that it will be unifying its brand strategy across its Power Systems business segment, which provides high-speed engines from 760 – 4400 hp and power generation equipment from 2–3,500 kW, including standby and prime power gen sets, alternators, switchgear and other components. Currently the portfolio features the Cummins, Cummins Power Generation and Cummins Onan brands. With immediate effect, the branding will be consolidated under the Cummins brand. The Cummins Power Generation and Cummins Onan brands will be retired and the Onan name synonymous with mobile gensets, will be repositioned as a generator product line under the newly unified Cummins brand in the RV market.

Cummins Inc. will also be permanently changing all “Fun Roads” branding to Cummins RV moving forward as well and the Fun Roads brand will also be retired. As Onan will now be repositioned as a RV product line, with the new rv.cummins.com website and social media platforms serving as tools for RVers across the country to find relevant information like product specs and our sales and service locator.

“Looking to unify Cummins into one cohesive, unified brand, we decided that consolidating both products (engines and generators) into the Cummins RV family only strengthens the brand and more uniformly speaks to our manufacturers and consumers,” said Jodie Wilson. “The brand changing will not affect product or service offerings, but will help us to continue on our promise of delivering dependability across the globe.”

Rebranding took place globally on all marketing activities, as product branding changed across all manufacturing plants beginning July 2017.[11]

Exhaust and emissions after-treatment company Nelson Industries was purchased in 1999, due to the increasing importance of exhaust after-treatment systems for meeting future emissions standards. The division officially changed its name to Cummins Emission Solutions, in order to be identified more closely with their parent company.
