The Cummins Engine Company was founded in Columbus, Indiana, in 1919 by Clessie Cummins, a local mechanic. It focused on developing the diesel engine invented 20 years earlier, but in spite of several well publicized endurance trials it was not until 1933 that their Model H, used in small railroad switchers, proved successful. In the post-World War II U.S. road building boom Cummins N Series engines became the industry leader, with more than half the heavy duty truck market from 1952 to 1959. In the 1960s the company opened an assembly plant in Shotts, Scotland. By 2013 they had operations in 197 countries and territories.
Cummins Engine Business Unit consists of Aftermarket support, Mid-Range, Heavy-Duty, and High-Horsepower 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.
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 1989. In 2007, 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 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.

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 1986, 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.
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.
