Original Equipment Manufacturer (OEM)

Cummins Westport natural gas engines are built in Cummins engine plants and delivered  to truck and bus OEMs where the engine is integrated into the vehicle. In some cases the OEM will also install the natural gas (CNG or LNG) vehicle fuel storage system. The fuel system can also be installed on the vehicle at a different location, such as a truck-body builder (e.g. refuse), as the vehicle is being configured to the customer's specifications.

Cummins Westport does not offer diesel to natural gas engine conversions. Our engines are designed and purpose-built to operate with natural gas.
