Demonstrating innovation in a variety of NOx reduction technologies

HANOVER, Germany. (September 23, 2014) – Recognizing that Selective Catalytic Reduction (SCR) technology is the right solution in many applications for meeting ever more stringent oxides of nitrogen (NOx) emissions reduction criteria across the globe, Cummins Emission Solutions continues to look at SCR-enabling technologies that could bring even greater benefits to its customers.  One such technology viable for light-duty diesel engines and highly transient duty cycle applications is an Ammonia Storage Delivery System (ASDS), which is being evaluated by Cummins Emission Solutions along with our partner Faurecia Emissions Control Technologies (FECT) and its affiliate Amminex. Research and development phases today suggest that a pure ammonia delivery solution could bring several advantages including improved NOx conversion efficiency at low temperatures, and the elimination of deposit formation associated with urea dosing systems, in addition to the many other advantages of SCR technology.

Cummins Emission Solutions has gained a wealth of SCR system experience since the technology’s introduction in Europe from 2005 and then inNorth America’s On-Highway markets from 2010. Cummins Emission Solutions is proud of its over 80 billion miles of experience – with over 1.7 million systems sold.  Following the On-Highway markets, the Off-Highway markets were introduced to the company’s SCR systems in 2013 as its Tier 4 Final NOx reduction technology.

Cummins Emission Solutions urea dosing system technologies are industry-leading solutions in meeting current NOx reduction requirements around the globe.  The EcoFit UL2 Liquid-Only Urea Dosing System is the only commercially available dosing system that offers high-flow dosing rates of up to 20.5 kg/hour.  This airless dosing system, offering flexible installation options and freeze-robust components, is an ideal solution for applications across both On- and Off-Highway markets.  The EcoFit UA2 Air-Assisted Urea Dosing System serves customers looking for an air-assisted dosing solution.  The system features unique centerline Diesel Exhaust Fluid (DEF) injection into the exhaust stream to optimize NOx conversion efficiency, while also offering improved system reliability and a reduction in deposit formation in the SCR system.

Along with today’s Selective Catalytic Reduction System solutions and the EcoFit UL2 Liquid-Only Urea Dosing System, an Ammonia Storage Delivery System (ASDS) solution will be on display at the IAA Commercial Vehicles Show in the Cummins booth.
