Cummins Next Generation EGR-Free 100 to 430 HP Engine Line-up for Stage V

Cummins launched the next generation of ultra-clean engines in April 2016, designed to meet European Union Stage V emissions regulations commencing in 2019 for construction, mining and materials handling equipment. Across a broad 74 hp to 400 hp output range (55 kW to 300 kW). The newly named F3.8, B4.5, B6.7 and L9 engines leap ahead of their Stage IV equivalent engines with 10 percent more power and almost 20 percent more torque averaged across the range.

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 4-cylinder F3.8 and B4.5, and the 6-cylinder B6.7 and L9, 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 the customer cares about, with easier installation, simplified servicing and more responsive power delivery. In the process, Cummins is raising the engine performance bar higher for the industry. The Stage V engines will be supplied as an integrated system with the Single Module TM 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 percent reduction in envelope size and a 30 percent 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 X12 powering equipment up to 512 hp (382 kW) and the X15 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 X12 and X15 will carry forward to the Stage V certified engines with no modification required to the existing engine architecture.
