Cummins ISB6.7 Engine Overview

ISB6.7 FOR EURO TRUCK & BUS

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.

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.

Additional ratings may be available.  Check with Qingbang.
