History

The Cummins Engine Company was founded in

, on February 3, 1919, by mechanic Clessie Cummins and banker William Glanton Irwin. The company focused on developing the

diesel engine The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-cal ...

invented 20 years earlier, but despite several well-publicized endurance trials, it was not until 1933, that their Model H engine, used in small railroad switchers, proved successful. The Cummins N Series engines became the industry leader in the post-World War II road building boom in the United States, with more than half the heavy-duty truck market using a Cummins engine from 1952 to 1959. In the 1960s, the company opened an assembly plant in Shotts, Scotland (closed in 1996). By 2013, Cummins had operations in 197 countries and territories. Cummins headquarters

Cummins Engine Business

Cummins Engine Business Unit consists of Aftermarket support, Mid-Range, Heavy-Duty, and High-Power Engines. Its markets include heavy-and medium-duty trucks, buses, recreational vehicles (RV), light-duty automotive, and several industrial uses including construction, mining, marine, oil and gas, railroad, and military equipment. One of the most popular engines made by the company is the 5.9-liter in-line six-cylinder engine used in the Dodge Ram light-duty pickups starting in 1988.5. In 2007.5, a 6.7-liter version of the Cummins straight-six engine became optional on the RAM pickup. 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. 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

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.

Cummins Power Systems

In 1986 Cummins began the 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 an 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.

Cummins Emission Solutions

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.

Clean Air Act violation

In 1998, the EPA announced fines totaling $83.4 million against Cummins and six other

manufacturers, the largest fine to date. The fines came after manufacturers evaded testing by deliberately deactivating emissions controls during highway driving, to give the appearance of being in full regulatory compliance during standard laboratory testing. The manufacturers also agreed to spend more than $1 billion to correct the problem. The trucks used engine ECU software to engage pollution controls during the 20-minute lab tests to verify compliance with the Clean Air Act, but then quietly disabled the emissions controls during normal highway cruising, thereby emitting up to three times the maximum allowed NOx pollution.
