Cummins Inc. will present one of the largest displays of Tier-4 Interim engines, exhaust aftertreatment and filtration products at ConExpo-Con/Agg 2011. The Cummins display will feature a full lineup of the latest-generation 3.3-liter to 15-liter engines, ranging from 60-hp to 600-hp.
Cummins Tier-4 Interim engines are engineered to deliver significantly higher fuel economy and improved engine response than their Tier-3 predecessors. This combination of higher performance and cleaner, low-emissions operation will be represented with a Tier-4 "Clear Advantage" message for visitors to the Cummins booth.
Cummins 6-cylinder QSB6.7, QSL9, QSX11.9 and QSX15 engines on display meet EPA Tier-4 Interim/EU Stage IIIB regulations for above 173-hp (129-kW) introduced Jan. 1, 2011. They are integrated with the Cummins particulate filter aftertreatment system to remove particulate matter emissions by operating with up to 99-percent passive regeneration in most applications, with no impact on equipment performance, according to the company.
For the Jan. 1, 2012, Tier-4 Interim/Stage IIIB emissions regulations covering the 75-hp to 173-hp (56-129 kW) category, the 4-cylinder QSB3.3, QSB4.5 and lower ratings of the QSB6.7 utilize the Cummins Compact Catalyst to remove PM. The catalyst is a fully passive, exhaust flow-through aftertreatment with a service-free fit-and-forget advantage for smaller equipment typically used by rental fleet applications.
Visitors to the Cummins booth, S-16615, South Hall, Level 2, will be able to talk to Cummins Tier-4 experts about the operational and service benefits of Cummins technology.
The complete suite of exhaust aftertreatment systems from Cummins Emission Solutions will be on display at the booth. Cummins Filtration will display an extensive range of engine filtration products, including the latest Direct Flow air cleaner, introduced for Tier 4 Interim.
Also on display will be the innovative VGT variable geometry turbocharger patented by Cummins Turbo Technologies.
ConExpo-Con/Agg 2011 will take place March 22-26 in Las Vegas at the Las Vegas Convention Center.
