Cummins’ next generation of the ISL engine is displayed on the Cummins stand (Hall 11, D19) for the first time at the IAA truck show in Hanover, germany this week.
Meeting Euro 6, it is ideal for premium rigid trucks, lightweight tractor units and heavy duty buses and coaches. The 8.9 litre engine range goes up to 380 ps for truck and coach installations, with a peak torque of 1700 Nm. For bus applications it is available up to 330 ps with 1500 Nm peak torque.
Neil Pattison, Director – Automotive Engine Business for Europe, Middle East and Africa, said: “Following the launch of our Euro 6 ISB engine earlier this year, we are pleased to show the Euro 6 ISL here at IAA for the first time. Cummins’ capability to integrate all of the key emissions technologies, from air intake to exhaust aftertreatment, has enabled us to develop leading packages for Euro 6. IAA gives us the opportunity to promote them to an international audience, reflecting our global automotive business”.
The latest version of Cummins ISL builds on the Euro 5 levels of performance, fuel efficiency and durability. Added to this is the combustion and after treatment architecture developed for the US EPA 2010 standard, with the proven engine technologies of cooled exhaust gas recirculation (EGR) and variable geometry turbocharging (VGT). These are tailored for European market operations and duty cycles The EGR System is re-designed for better integration with cab-over applications and the Cummins VGT is optimised for high torque and low speed capability, delivering significant performance and driveability improvements. The VGT works as an exhaust brake, allowing the OEM to simplify their installation.
The system is controlled by a new electronic control module (ECM) with increased capability for controlling engine and aftertreatment with more challenging on-board diagnostics (OBD) monitoring requirements at Euro 6.
