Cummins Clean Fuel Technologies introduced its new series of back-of-cab fuel systems for compressed natural gas and renewable natural gas trucks.

Available in 135 diesel gallon equivalent (DGE) and 175 DGE capacities, the new lighter-weight systems include enhancements such as:

• A redesigned roof for improved aerodynamics.

• A new extruded aluminum frame.

• Smaller overall dimensions to accommodate all truck OEMs.

The overall weight has been reduced by about 400 pounds, with a more advanced lightweight structure and simplified plumbing arrangement.

With fewer fittings and an easier-to-remove cover assembly, the new BOC systems are designed to help reduce annual inspection time and ease troubleshooting for technicians.

Cummins' back-of-cab fuel systems come standard with the GreenLync 3.0 electronics communication system, recently enhanced with heat detection in the CNG cabinet, onboard diagnostics with multiple screen settings, and a robust electronic control unit housed inside the integrated fuel management module, which broadcasts an alert to the driver via in-dash screens. The system provides real-time information to drivers, fleet managers, and technicians to help manage, diagnose, and service CNG vehicles. It's designed to reduce false occurrences of engine fault codes and can integrate with telematics platforms to enable fleet managers to understand their vehicle performance.

Now in production, The BOC 135N and 175N systems paired with a Cummins X15N engine receive the same base warranty coverage as the engine — two years/250,000 miles.
