Cummins to Show 99% Passive-Regeneration Emissions Technology at CONEXPO

See examples of the full line of emissions-certified diesels at booth number S-16615

Columbus, Ind. – Cummins Inc. (NYSE: CMI) 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 at booth number S-16615.

Cummins claims its Tier 4 Interim engines are delivering significantly higher fuel economy and improved engine response than their successful 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 (PM) emissions by operating with up to 99 percent passive regeneration in most applications, with no impact on equipment performance.

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 in rental fleet applications.

A cooled Exhaust Gas Recirculation (EGR) system features on all Cummins Tier 4 Interim engines above 74-hp (55-kW). EGR efficiently reduce Oxides of Nitrogen (NOx) emissions by lowering the combustion temperature.

Completing the Cummins engine lineup at the show is the B3.3, certified for current Tier 4 Interim emissions across a 60-hp to 74-hp (45-55 kW) range, without the need for aftertreatment, EGR or electronic controls to offer a cost-effective power solution.

Visitors to the Cummins booth, S-16615, South Hall Level 2, will be able to talk to Tier 4 experts about the operational and performance benefits of Cummins technology.

The ability to utilize key enabling technologies from within Cummins own resources has been a major factor in realizing a “Clear Advantage” for Tier 4, resulting in better integrated packaging and enhanced performance.

A complete suite of exhaust aftertreatment systems from Cummins Emission Solutions will make an impressive display on the booth. Cummins Filtration will show an extensive range of engine filtration products, including the latest Direct Flow™ air cleaner, introduced for Tier 4 Interim.

Also on show will be the highly innovative VGT variable geometry turbocharger patented by Cummins Turbo Technologies. Other notable features at the Cummins booth include Tier 4 Interim installation-ready power units supplied by Cummins Power Products. Cummins Power Generation will present a compact trailer unit with 100-kW output, ideally suited for construction sites.

The Cummins display will be complemented by the latest version of the legendary Cummins-powered Ram truck, bringing our EPA 2010 on-highway emissions success to the show. CONEXPO-CON/AGG 2011 will take place March 22-26 in Las Vegas.
