The History Of Cummins®


Cummins Inc®. is a global power leader that designs, manufactures, distributes and services diesel and natural gas engines and power generation equipment. The company has a rich history that spans over a century, during which it has grown from a small business to a global leader in the manufacturing of engines and power systems. In this article, we will explore the history of Cummins® engines and take a look at some of the best-selling engines in the company’s history.

Cummins® Origins

The origins of Cummins® dates back to 1911 when the race car driver Ray Harroun invited mechanic Clessie Lyle Cummins to join his pit crew having heard of his outstanding reputation as a mechanic. As part of Harroun’s team, Cummins® advised improvements to increase the speed of his car, consequently helping the ‘Marmon Wasp’ secure the winners position in the first ever Indianapolis 500 Mile Race on May 30, 1911. This was Harroun’s final race before retirement.

History of Cummins® Engines

By 1919 Cummins® had sought investment from banker William Glanton Irwin to set up Cummins Engine Co®. in Columbus, Indiana. The company pioneered the use of technology developed by German engineer Rudolf Diesel in the late 1800s. The company initially found success in marine engines, before developing engines for the automotive industry. Diesel engines were not widely used in the 1920’s, but by the early 1930’s, with diesel fuel costing 1⁄3 the price of gasoline, the use of Cummins® diesel engines grew. During this period the Cummins® Model H engine was being used in railroad switchers, and by 1932 Kenworth became Cummins® first customer for H engines in their fleet of trucks.

Reputation For Quality

The Cummins Engine Co®. (now Cummins, Inc) became synonymous with quality and was the first to offer customers a 100,000 mile warranty. Over the next few years, Cummins® engines gained a reputation for being reliable and durable, which led to increased demand for the company’s products.

The Growth Of Cummins®

Under the leadership of J. Irwin Miller, the great-nephew of William G. Irwin, the company grew rapidly and expanded into worldwide markets, opening a manufacturing facility in Scotland in 1956, their first manufacturing facility outside of the United States. During this time, the post World War II road building boom in the US helped ensure the continued growth of the Cummins Engine Co.® with more than half the heavy-duty truck market using a Cummins® engine. By the 1960’s the company had established a presence in nearly 100 countries worldwide. During 1965 Cummins® opened another UK manufacturing plant based in Darlington, England, followed in the 1970’s with a plant in Daventry for K-series engines. After the war, the company continued to innovate and expand its product line, introducing new engines for trucks, buses, and industrial equipment. In the 1980s, Cummins® introduced a new line of engines that used electronic controls to optimize performance and reduce emissions. These engines were widely adopted by the trucking industry and helped to establish Cummins® as a leader in engine technology.
