Hannover, Germany (September 19, 2012) - Cummins’ next generation of the ISL engine is displayed on the Cummins stand (Hall 11, D19) for the first time at IAA today. 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.
“The engine uses Cummins XPI fuel system, delivering clean responsive power, enabling it to work as hard as higher displacement engines,” added Pattison.
The ISL uses the same style of aftertreatment system as developed for the ISB. It has been specifically designed and developed in Europe by Cummins Emission Solutions for Euro 6. It comes in a switch back configuration for compact installations and is packaged ready for OEMs to fit direct to their chassis. Controlled by the engine ECM, it incorporates a Diesel Particulate Filter (DPF) with Selective Catalytic Reduction (SCR) to meet the ultra-low levels required at Euro 6.
A patented SCR design uses Copper Zeolite technology for very high conversion efficiency, even at low temperatures. The airless Adblue dosing nozzle is integrated in the system for improved reliability and durability. Adblue consumption is expected to be around 3-5% of diesel consumed.
In addition a revolutionary new nanotechnology based filter media has been introduced offering 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 the 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.
“At Euro 6, we are able to at least maintain the excellent fuel economy levels and low Adblue consumption rates from Euro 5 on the ISL. This means operators can opt for Euro 6 with minimal operating cost impact,” concluded Pattison.
