Cummins ISB 6.7 engine Overview

The ISB is unique to Cummins, with no other manufacturer able to offer the same design benefits. It provides truck and bus manufacturers with an extremely cost-effective power plant, backed by the renowned dependability of the Cummins B engine platform. 

The latest design improvements form the basis of Cummins strategy to provide evolutionary product updates which continue to move the company significantly ahead of the competition.

The ISB6.7 is ideally suited for rigid trucks, buses and speciality vehicles due to the high torque and power for an engine of its size.  It is used in application classes traditionally associated with engines of higher displacement, all with the reliability and durability expected from Cummins. 

 Weight sensitive installations such as multi-axle rigid trucks and size constrained installations such as full size and double deck buses are easily in the reach of the ISB’s capabilities. It is used in a number of diesel-electric hybrid installations.

All this performance has been delivered with a high level of refinement. 

The ISB exceptionally quiet and smooth for a diesel of this size, with noise even further reduced from Euro 5 to Euro 6.   It is available up to 310ps for trucks and 280ps for buses, with a strong peak torque of 1100Nm.
