Cummins Continues Stage V Progress

Munich, Germany

MUNICH, GERMANY – Stage V continues to be a key focus for Cummins Inc. (NYSE: CMI) at Bauma 2019.

Alexei Ustinov, Vice President Off-Highway Engine Business said: “Since unveiling our Stage V construction engines at Bauma 2016, we have made great progress and are in production with all engine models from F3.8 to X15.  We have over 200 machine installations completed or in progress, which is more than at Stage IV, and our customers benefitting from key product updates that deliver more with less. We are developing alternate power capability such as hybrid, electric and fuel cells, however Stage V remains a key part of our plan.” 

Cummins Stage V products come with more power and torque, are less complex and easier to install, and require less servicing. This offers OEMs the ability to increase machine capability and offer more value or downsize engines to reduce cost. The B6.7 (displayed at Bauma) reflects 100 years of engine innovation, offering 30 percent higher torque than Stage IV with 243 kilowatts (kW) (326 horsepower) of power, enabling it to replace engine of higher displacement with no impact on machine operation. 

Also featured at Bauma will be the Stage V F3.8 power unit. Delivered as a complete and ready-made power package, it comprises an engine, Single Module™ aftertreatment, radiator and cooling system – as well as auxiliaries such as mounting feet, hoses and an air cleaner. The unit is more than 70 percent pre-approved for installation, reducing customers’ time and resources for integration.

Stage V engines and power units are available from 75 – 503 kW (100–675 horsepower).

Mining
2019 Stage V is the first European emissions step which impacts engines above 560kW (750 horsepower). At Bauma, Cummins will debut the QSK60 Stage V engine which is part of its 560-2611 kW (750-3500 horsepower) mining line up. The QSK60 is available from 1398-2125 kW (1875-2850 horsepower) for excavator and dump truck use with a proven durability of close to 4.2 million liters (1.1 million U.S. gallons to overhaul). 

A redesigned power cylinder, optimised wastegate turbocharging and improved crankcase breather system work to keep particulate matter (PM) below the Stage V levels. Cummins modular Selective Catalytic Reduction (SCR) system is used to reduce nitrogen oxide (NOx) to the required level and features an integrated decomposition chamber and Cummins’ airless dosing system designed to last the life of the engine. The use of SCR reduces engine backpressure, for increased fuel economy and optimised temperature management minimises Adblue/DEF consumption.  

The two-stage QSK60 engine features a simplified air handling configuration using Cummins turbochargers with intercoolers to achieve an altitude capability of over 3,500 meters with easy access to the top end for servicing.

The latest NanoNet® filtration technology captures and retains more harmful particles than traditional media, for longer fuel pump and injector life with better reliability. 

“Cummins Tier 4 Final combustion and emission technology solution for North America has positioned us to meet Stage V with minimal OEM impact. Using proven SCR technology with the renowned reliability and durability of the QSK range means customer can select Cummins with no concerns,” added Ustinov.

G-Drive
Cummins announced the availability of fixed speed G-Drive Stage V engines for Bauma. The benefits seen with the variable speed Stage V engines of higher power density and reduced complexity (by the removal of Exhaust Gas Recirculation and using a simpler aftertreatment system) have been carried over, with further optimisation for generator set use. 

“The increased power capability could offer downsizing opportunities with easier installation to GOEM customers,” concluded Ustinov.   

Initially B6.7 and L9 stand-by and prime power ratings at 50 and 60 hertz will be available (listed below), with other engines to follow later.
