isxe5-bCummins has a new addition to its heavy-duty truck engine line-up in Australia.

The ISXe5, an engine meeting Euro 5 emissions compliance through selective catalytic reduction (SCR) technology, will be available in Australia starting in 2013.

Australia is the first market in the world to offer the ISXe5. It will be sold alongside Cummins’ market-leading ISX and Signature engines, which use cooled exhaust gas recirculation (EGR) and a diesel particulate filter (DPF) to meet Australian Design Rule 80/03 emission requirements.

The ISXe5 will have the same ratings as the current EGR engines, from 450 to 600 hp and 1650 to 2050 lb ft of torque.

All ISXe5 engines will include the Cummins Intebrake, providing the strong engine brake retardation for which the ISX and Signature engines are renowned. All ISXe5 ratings 485 hp and above will feature peak retardation of 600 hp.

The SCR exhaust aftertreatment on the ISXe5 is a fully integrated system developed by Cummins Emissions Solutions (CES), dosing urea into the exhaust stream to reduce oxides of nitrogen (NOx) emissions.

Cummins’ truck engine line-up in Australia includes a number of other engines using this aftertreatment system, including the ISFe5, ISBe5, ISLe5 and ISMe5.

Cummins has been field testing 10 ISXe5 engines in Australia since early 2012 as part of the development program for this engine, and now has more than 20 trial engines in service across a range of heavy-duty applications.

The ISXe5 will go into production at Cummins’ Jamestown plant in the U.S. for availability in Australia in 2013.

    I’ve been fortunate enough to work on your newer versions of scr,and have wonder why Cummings has only incorporated only 1 nh3 sensor downstream,and not a nh3 senior upstream.Regardless the system is truly amazing growing up in Los Angeles the skies have cleared a lot better when I go out I can see the mountains a Hugh difference compared to the late 80s and early 90s when a Hugh black donut circled the city.Thanks for the God given talent of these awesome and intriguing designed filters.
