Cummins Inc. will feature one of the most impressive engine line-ups ever seen at the bauma show (Munich, April 15 to 21), with a "smallest-to-largest" engine display featuring the QSF2.8 at 49 hp (37 kW) and the QSK95 at up to 4,200 hp (3,132 kW). The 2.8-liter and 95-liter engines highlight the recent extension of Cummins power at both the low and high ends of the range, now the broadest and most capable in the industry of meeting Tier 4 Final emissions. 

The four-cylinder QSF2.8, with 49 hp to 74 hp (37 to 55 kW) output, is the smallest-ever Cummins engine to be introduced with full-authority electronic management and a High Pressure Common Rail (HPCR) fuel system. Small in size and light in weight due to the innovative use of composite materials, the QSF2.8 is ideally suited for highly compact equipment such as skid steer loaders and mini-excavators, offering easier installation for Tier 4 Final/Stage IV by utilizing Cummins Compact Catalyst (CCC) aftertreatment with a "fit-and-forget" advantage.

The QSK95 is the most powerful 16-cylinder engine ever designed for ultra-class mine haul trucks with up to a 400 ton (363 mt) payload, capable of a remarkable 4,200 hp (3,132 kW) output previously thought possible only for a 20-cylinder engine. Tier 4 Final emissions levels are achieved using a Selective Catalytic Reduction (SCR) aftertreatment system developed by Cummins Emission Solutions for very high power output applications.

High power density is achieved with a hardened power cylinder featuring the strongest single-piece forged-steel piston available in the industry. Deep structural strength equips the QSK95 for exceptionally long life, and it is able to consume over 1.7 million gallons (6.4 million liters) of fuel before engine overhaul. Despite the huge difference in size and output between the QSF2.8 and the QSK95, the two engines share a similar Cummins electronic control system, bringing the benefit of diagnostic commonality supported by a worldwide service network.
