Cummins

The power of true reliability.

Founded in 1919 by Clessie Lyle Cummins, the company grew from a small workshop in Columbus, Indiana into a global leader in power. Cummins designs, manufactures, and services diesel and alternative-fuel engines, along with the filtration, turbocharging, power-generation, and electrified systems that support them. Through every era its aim has stayed the same: to build engines people can count on, wherever the work takes them.

Betting on Diesel

In the 1920s, few believed the diesel engine had a place outside heavy stationary use. Clessie Cummins thought otherwise. He worked relentlessly to prove diesel's efficiency and durability, famously putting his engines in cars and trucks and running record-setting endurance drives to win over a skeptical public. That determination established Cummins as a pioneer that helped bring diesel power into everyday commercial and industrial use.

Power for Every Application

Today Cummins builds a broad range of engines and power systems for on-highway trucks and buses, construction and agricultural equipment, mining, rail, marine, and standby and prime power generation. Its diesel engines are known for the pulling power, fuel efficiency, and long service life that operators depend on, and the company continues to expand into natural gas, hydrogen, and fully electric powertrains.

Backed Around the World

Cummins supports its engines through one of the largest service and distribution networks in the industry, with parts, dealers, and trained technicians spanning the globe. That reach, paired with ongoing investment in cleaner and more efficient power, keeps Cummins engines working hard in the field and keeps owners confident that support is never far away.
