The Cummins Engine Company was founded in Columbus, Indiana on February 3, 1919, by mechanic Clessie Cummins and banker William Glanton Irwin. The company focused on developing the diesel engine, which was invented 20 years earlier. Despite several well-publicized endurance trials, it was not until 1933 that their Model H engine, used in small railroad switchers, proved successful.^{[self-published source]} 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 of the heavy-duty truck market using Cummins engines 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 Component Business Unit consists of emission solutions, filtration (Fleetguard), fuel systems, turbo technologies (Holset), and electronics. The Cummins Turbo Technologies unit designs and manufactures turbochargers and related products on a global scale, for diesel engines above 3 liters. Its Emission Solutions unit develops and supplies catalytic exhaust systems and associated products to the medium and heavy-duty commercial diesel engine markets. Cummins Filtration designs, manufactures and distributes heavy-duty and light-duty air, fuel, hydraulic and lube filtration, chemicals and exhaust system technology products for diesel and gas-powered equipment. In contrast Cummins Electronics designs engine control units and sensors for Cummins diesel engines.

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, gas, railroad and military equipment.

One of the most popular engines built is the 5.9-liter I6 engine used in the Dodge Ram heavy-duty pickups starting in 1988. 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 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 ship 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.

Cummins has a technical center in Darlington, England, for developing products for the European, Middle Eastern, and Asian markets.
