Cummins Inc. will present the next generation of ultra-clean engines at the BAUMA show (Munich, April 11-17) designed to meet European Union Stage V emissions regulations commencing in 2019 for construction, mining and materials-handling equipment. Across a broad 74- to 400-hp output range (55 to 300 kW), these engines will go beyond meeting Stage V near-zero emissions regulations to bring an increase in power and torque of up to 10%t.

The Stage V enhancements to engine performance are being achieved by taking an innovative approach to combustion, air flow and fuel injection systems, allowing Cummins to realize the full potential of the four-cylinder QSF3.8 and QSB4.5, and the 6-cylinder QSB6.7 and QSL9, without the need to increase displacement.

"Cummins is taking the opportunity offered by the introduction of Stage V regulations in 2019 to redefine engine performance in terms that our customers care about, with easier installation, simplified servicing and more responsive power delivery. In the process, we will be raising the engine performance bar higher for the industry," said Hugh Foden, Executive Director - Cummins Off-Highway Business.

The Stage V engines will be supplied as an integrated system with the Single Module exhaust aftertreatment, newly developed by Cummins Emission Solutions in response to the needs of increasingly space-constrained equipment. The Single Module will provide up to a 50% reduction in envelope size and a 30% reduction in weight compared with the existing Stage IV and Tier 4 Final aftertreatment systems.

The efficient packaging of the Single Module is achieved in conjunction with ultra-clean performance that removes 99 percent of Particulate Matter (PM) emissions, as well as reducing Oxides of Nitrogen (NOx) emissions to extremely low levels.

Cummins heavy-duty engine duo, the QSG12 powering equipment up to 512 hp (382 kW) and the QSX15 with a 675 hp (503 kW) top rating, are ready to meet Stage V regulations by retaining the Diesel Particulate Filter and Selective Catalytic Reduction (DPF-SCR) aftertreatment system used for Stage IV and Tier 4 Final applications. For those larger, high-output machines, the Cummins DPF-SCR provides an established installation package with ongoing continuity for equipment manufacturers as they transition their machines to Stage V compliance in 2019.

The significant increase in peak power and torque rise achieved at Stage IV and Tier 4 Final by the QSG12 and QSX15 will carry forward to the Stage V-certified engines with no modification required to the existing engine architecture.

The full lineup of next generation Cummins engines to meet Stage V regulations will be revealed on the opening day of BAUMA at Hall A4, Stand 325.
