Cummins ISB 6.7

Power 200 - 350 hp

Torque 520 - 750 lb-ft

The ISB was designed to meet stringent global emissions regulations while delivering high performance and low operating costs. The Cummins ISB 6.7 is used primarily in medium duty trucks and buses, however, as with many quality diesel engines throughout the world, they have been adapted for a variety of uses from agriculture to industrial. The ISB 6.7 comes from the original B series engines produced by Cummins starting in 1984. The B series engine is one of the most successful diesel engines ever made and continues to be produced today.

The ISB 6.7 was the first diesel engine produced by Cummins that included a diesel particulate filter (DPF). DPF systems greatly reduce emissions by collecting soot and essentially ‘burning it off’ with high heat generated by the engine’s exhaust. Cummins continued to make improvements in the ISB 6.7 engine - the 2019 Cummins 6.7L achieved an impressive 1000 lb-ft torque while still meeting emissions standards while maintaining fuel economy.
