Cummins Inc. is a U.S. company that designs, manufactures and distributes diesel and natural gas engines and related products such as filters and turbochargers.
Founded in Columbus, Indiana in 1919 by Clessie Cummins, the company reported sales of $17.3 billion in 2013 and employed 33,700 people. It is listed on the New York Stock Exchange.
In its early days, the company specialized in the industrialization of the internal combustion engine invented 20 years earlier by German industrialist Rudolf Diesel, but despite several widely publicized trials, it was not until 1933 that it managed to launch its first truly popular model on the market: the H diesel engine, which equipped locotractors.
With the post-war highway boom in the U.S., Cummins established itself as the leader in heavy-duty truck engines with the N-type diesel engine, with more than 50 percent market share between 1952 and 19594. In the 1960s, the company opened a European plant in Shotts, Scotland. By 2013, they are established in 197 countries.
