CMI

Cummins Inc

A maker of diesel, natural gas, and gasoline engines and power-generation equipment, Cummins builds the powertrains and generators that move and power trucks, buses, and industrial machinery across the globe. It was founded in 1919 in Columbus, Indiana, when self-taught mechanic Clessie Cummins convinced his banker boss William Irwin to back his diesel-engine idea. To prove his engines worked, Clessie drove a Cummins-powered truck coast to coast in 1931, and his diesel race car became the first to finish the Indianapolis 500 without a single pit stop.
