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.

• Electronic Integration – industry standard datalink accepts inputs from all powertrain components including electronic transmissions, ABS brakes and ASR antislip. Creates a seamless flow of information shared along a high speed network.
•  Electronic Control Module (ECM) – with increased capability it maintains an optimum balance between load demands, fuel efficiency and emissions. The ECM ensures that the engine and aftertreatment meet the more challenging on-board diagnostics (OBD) monitoring requirements for Euro 6.
• Electronic Protection – sensors throughout the engine continually send data back to the ECM for self diagnosis and protection. Rapid diagnostics and data downloading are available, helping to ensure maximum uptime for vehicles.
• High Pressure Common Rail fuel system – works at higher pressure and provides more precise control of the combustion process. Capable of generating up to 1800 bar injection pressures for refined and rapid power delivery, reduced noise, and improved cold start.
• Variable Geometry Turbocharger – developed by Cummins Turbo Technologies the VGT is optimised for high torque and low speed capability, delivering significant performance and driveability improvements.
• Latest Engine Filtration – a new nanotechnology based fuel filter media offers unmatched protection for the engine’s fuel system, removing up to 98.7% of all particles as small as 4 microns. The filter’s replaceable service element has less environmental impact than its predecessor, and unique patented no-filter, no-run design prevents the engine from running without a media element installed, eliminating the risk of debris entering the engine.
• New Aftertreatment System – a switch back configuration for compact installations, packaged ready for manufacturers to fit direct to their chassis. Controlled by the engine ECM, it incorporates a Cummins Particulate Filter (CPF) with Selective Catalytic Reduction (SCR) to meet the ultralow levels required at Euro 6. A patented SCR design uses Copper Zeolite technology for very high conversion efficiency, even at low temperatures.
• Emissions Control – the EGR and SCR systems are closely balanced to meet the regulated NOx levels and optimise the fuel economy and Adblue usage for the lowest possible running costs.
• EPA 2010 engine technology – prove cooled exhaust gas recirculation and variable geometry turbocharging has been tailored for a 6 cylinder product and European vehicle operations.
• Rear Engine Power Take-Off (REPTO) with a drive capability of 400Nm is available. It is suitable for applications such as cement mixers.
• Closed crankcase ventilation (CCV) – new system mounted to the engine valve cover required to re-cycle blow-by gases now counted in the engine emissions. Positioned for cab over truck designs.
