Cummins working towards next round of emissions

COLUMBUS, Ind. — Cummins revealed it’s continuing to make progress toward meeting the stringent 2011 EPA Tier 4 off-road, and EU Stage IIIB emissions regulations.

Development work has now moved from test cell research to equipment level systems integration by Cummins. Combustion simulation and prototype work began as early as 2005.

“Utilizing analysis led design tools together with up to 100,000 test cell hours and 50,000 field test operating hours anticipated by program launch, we are confident in our ability to provide the best value integrated system to the off-road markets,” commented Ric Kleine, vice-president of Cummins Off-Highway Business.

Cummins Particulate Filter and Selective Catalytic Reduction systems are proven aftertreatment technologies capable of meeting 2011 off-road emissions levels for engines above 100 hp (75 kW).

“Cummins has invested significantly in a broad technology portfolio which extends from air intake to exhaust aftertreatment, including High-Pressure Common Rail fuel systems, controls and advanced turbocharging, said Kleine. This means we can fully integrate all the key subsystems more effectively. EPA and EU emissions reductions require the use of exhaust aftertreatment, and the company is evaluating alternatives to minimize the impact on installation complexity for the equipment manufacturers.”

Installation and operational aspects of these systems are currently being evaluated for off-road applications. By 2008 Cummins will be in a position to identify which of these systems offers the best value and performance proposition for construction equipment customers.

“Because of our investment in all the critical technologies, we are able to leverage our vast experience in other markets where exhaust aftertreatment systems are already in production. Our stable technology base enables Cummins to focus on achieving the lowest initial cost for the OEM and on the lowest cost of operation for the equipment owner,” added Kleine.

By combining enhanced engine platforms with integrated aftertreatment systems, Cummins test cell research has achieved the 90% reduction in PM (Particulate Matter) and 45% reduction in NOx/HC (Oxides of Nitrogen/Hydrocarbon) emissions required by the EPA.
