Cummins unveils new Stage V engines
May 17, 2016 - Cummins Inc. Chairman and Chief Executive Officer Tom Linebarger recently unveiled a new generation of ultra-clean engines designed to meet European Union (EU) Stage V emissions regulations in 2019 at the Bauma Show in Munich. The new F3.8, B4.5, B6.7 and L9 engines, ranging from 100 hp to 430 hp (75-321 kW), achieve a major increase in power and torque by removing the Exhaust Gas Recirculation (EGR) system and using Cummins Single Module(TM) aftertreatment technology.
“Cummins is raising the engine performance bar higher with our EGR-free approach forStage V, and that leadership will continue to drive the equipment industry forward to meet the regulations in 2019 with simpler machine integration,” commented Linebarger at the new engine launch.
“The engines we unveiled today have been designed from the outset to reduce Stage V cost of ownership to levels equivalent to that of engines meeting emissions regulations as far back as 10 years ago. This achievement is the result of product development inspired more than ever by the needs of our customers rather than by just meeting emissions regulations, however stringent they may be,” added Linebarger.
Compared with that of current Stage IV and Tier 4 Final engines, power output of the new 3.8-liter to 9-liter engines for Stage V is increased by over 10 percent on average, and peak torque is increased by almost 20 percent. The combined cost of fuel and urea consumption is reduced by 3 percent on average, depending on application.
The X12 and X15 engines complete the Stage V line-up, taking output up to 675 hp (503 kW) for heavy duty applications. The F3.8 is also available at a 74 hp (55 kW) rating, ideally suited for compact equipment requiring high levels of torque.
