Based on the experience of over 10 million B Series engines to date, the ISB comes with a pedigree of performance and fuel efficiency which continues to improve with each generation.  Developed to meet stringent emissions regulations around the world, it offers the same product enhancements wherever it is used. For operators in Europe, Turkey, Russia, China, Brazil or India, for emissions from Euro 2 through to Euro 6, there is an ISB for you.

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.

For Euro 6 emissions, key design enhancements are incorporated whilst delivering the best possible levels of performance and running costs.   This is achieved using proven emission technologies of cooled exhaust gas recirculation (EGR),variable geometry turbo (VGT), diesel particulate filtration (DPF) and Selective Catalytic Reduction (SCR), all tailored for European vehicle designs, operation and emissions. 

Cummins Engineers have the experience to work with vehicle manufacturers to install the engine and related technologies and deliver the best possible result in terms of emissions and running costs.  Cummins is the natural choice for Euro 6.

For 2017 the ISB6.7 has moved further forward, offering added value in a market where competitive fuel economy and total cost of operation are critical success factors.  A new peak torque of 1200 Nm, with improved bottom end torque delivers better performance.  New top ratings of 300 hp/224 kW for buses and 320 hp/239 kW for trucks increase the engine’s capability, being suitable for wider range of applications, vehicle weights and duty cycles. 

Features & Benefits

• 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.
