Comparison of SCR Catalyst Performance on RMC SET Emission Cycle between an Engine and a High Flow Burner Rig 2013-01-1070

Government agencies like EPA play an important role through regulation to reduce emissions and fuel consumption and to drive technological developments to reduce the environmental impact of burning petroleum fuels. Emissions testing and control is one of the leading and growing fields in the development of modern vehicles. Recently, Cummins Emissions Solutions (CES) and Southwest Research Institute (SwRI) worked jointly in order to achieve a method to conduct emissions testing efficiently and effectively. The collaborative work between the two organizations led to the usage of FOCAS HGTR™ (a diesel-based burner test rig at SwRI) to simulate the exhaust conditions generated by a 2010 ISX Cummins production engine operating over an EPA standard Ramped Modal Cycle Supplemental Emissions Test (RMC SET) cycle. The diesel-fueled HGTR burner rig went through a series of developments and modifications to permit the system to run quasi-transient control and enable it to simulate RMC SET cycles similar to an ISX engine. This paper discusses different aspects of this work.
