Founded in Columbus, Indiana, in 1919 as Cummins Engine Company, for its namesake Clessie Lyle Cummins, the fledgling firm was among the first to see the commercial potential of the engine technology invented two decades earlier by Rudolf Diesel.

After a decade of fits and starts, in 1933, the company released the Model H, a powerful engine for transportation that launched the company's most successful engine family. J. Irwin Miller, became general manager in 1934 and went on the lead the company to international prominence over the next four decades. By marketing high-quality products through a unique nationwide service organization, the Company earned its first profit in 1937. Three years later, Cummins offered the industry's first 100,000-mile warranty.

By the 1950s, United States had embarked on a massive interstate highway construction program, with Cummins engines powering much of the equipment that built the roads and thousands of the trucks that began to roll down them. Truckers demanded economy, power, reliability, and durability, and Cummins responded. By the late 1950s, Cummins had sales of over $100 million and a commanding lead in the market for heavy truck diesels.

As Cummins continued to grow its business in the United States, the Company also began looking beyond its traditional borders. Cummins opened its first foreign manufacturing facility in Shotts, Scotland, in 1956 and by the end of the 1960s, Cummins had expanded its sales and service network to 2,500 dealers in 98 countries. Today, Cummins has more than 5,000 facilities in 197 countries and territories.

Cummins, led by the visionary leadership of J. Irwin Miller, forged strong ties to emerging countries such as China, India and Brazil, where Cummins had a major presence before most other U.S. multinational companies. Cummins has grown into one of the largest engine makers in both China and India, and for the past three years approximately half of the Company’s sales have been generated outside the United States.

Cummins was the only company in the industry to meet the 2010 Environmental Protection Agency standards for NOx emissions with the release in early 2007 of its new 6.7-litre turbo diesel for the Dodge Ram Heavy Duty pickup.

Its markets include heavy-and medium-duty truck, bus, recreational vehicle (RV), light-duty automotive and a number of industrial uses including agricultural, construction, mining marine, oil and gas and military equipment.[3]

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.[4]

In 2007, a 6.7 liter version of the Cummins straight six engine became optional on the Dodge Ram pickup (standard with the class 4 and class 5 chassis).[4]

Cummins Turbo Technologies

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 1986, Cummins began acquisition of Onan and completed it in 1992. 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 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 to be identified more closely with their parent company.


High-horsepower (larger than 19 liters displacement) engines are manufactured in Seymour, Indiana, Daventry, England, and Pune, India. Heavy duty (10–19 liter displacement) M and X series engines are manufactured in Jamestown, New York. The B, C and L series engines are manufactured in numerous plants across the world.
