Application specific tailoring

Cummins provides a wide variety of off-the-shelf engines and generators for military applications. But as vehicles are expected to meet new requirements, have more power density and increase fuel economy, Cummins is easily able to adapt.​ Cummins can assist at every phase, from providing guidance on initial bid specifications to working with Original Equipment Manufacturers (OEMs) on installation, field testing and production.

Customizing commercial off-the-shelf models provides advantages in availability, reliability and space claim requirements.​

We can also create entirely new engine designs depending on your needs and specifications. The ACE engine began as a customer request for an opposed-piston design.​
