History of Cummins Engines

Some CUMMINS Engines Service Manuals PDF are above the page.


Cummins was founded in 1919 by Clessie Cummins with the support of local banker and investor W. G. Irwin.


Clessie was one of the first to see the commercial potential of the engine invented by Rudolph Diesel two decades earlier.


Initially, it produced engines for agricultural machinery with a capacity of 4.5 kW (6 hp) under license, but soon Cummins began to develop engines of its own design.


In 1932, an advertising campaign was organized at the Indianapolis Motor Speedway, where a truck with the new Cummins Model H 6-cylinder engine covered 14,600 miles (about 23,500 km) in uninterrupted mode for two weeks.


In 1952, at the world famous Indianapolis 500 Mile Competition, the Cummins diesel racing car took the coveted pole position at the start. This experiment helped prove the feasibility of using a turbocharger for diesel engines.


By the late 1960s, Cummins became international with 2,500 dealerships and service centers in 98 countries.


Over the past decades, Cummins has been pursuing a strategy for the development of new technologies and investing in new projects, constantly improving environmental, technical and managerial aspects, Cummins has been steadily holding a leading position in the field of diesel engine technology.


They are assembled by these units and their accessories in four countries: USA, China, Turkey and Russia.
