Cummins is pleased to announce its engineers have completed 100 Stage V customer installations to date, with 30% being brand new ones. These include air compressors, back-hoe loaders, dump trucks, fork lift trucks, container handlers, drills, pavers, cranes, excavators, wheeled loaders and snow groomers.
From 74 to 503 kW (100-675 hp), Cummins Stage V engines do more with less, delivering benefits for equipment operators and manufacturers. For operators of construction equipment, they deliver higher performance for more machine capability. Simpler architecture with fewer parts means more reliability, and more productivity. Improved fuel efficiency with extended service intervals drives lower running costs. The engines are more compact with less weight, less to cool, less installation complexity and lower installation cost for manufacturers.
“Whilst most manufacturers have adopted a ‘same as’ strategy from Stage IV to Stage V with little change, Cummins technology leadership has enabled us to deliver improved products with reduced complexity for our customers. For example the Single ModuleTM aftertreatment and its higher NOx conversion capability has supported the removal of EGR from our 3.8 to 9 litre engines. This has positioned us for opportunities with manufacturers who had not necessarily considered Cummins in the past,” said Hugh Foden, Executive Director, Off-Highway Business.
Cummins B6.7 and L9 Stage V products will be certified and ready to start production in April, eight months in advance of the legislated date. They both offer higher power output and torque for improved machine capability. Top-rated power for the Stage V B6.7 moves up to 243 kW (326 hp) with a peak torque of 1375 Nm –a 30 percent increase over that of Stage IV. The L9 top rating increases from 298 kW (400 hp) up to 321 kW (430 hp) at Stage V together with a 13 percent increase in peak torque to 1846 Nm.
“The higher capability of our Stage V engines is delivering down-sizing opportunities for our OEM customers. For example, the B6.7’s increase in capability means that it is replacing engines of higher displacement with no impact on equipment operation. This is delivering reductions in initial installation costs for OEMs as well as running costs for operators,” added Foden.
The F3.8 and B4.5 engines will also be ready prior to the required date of 2020, with substantial increases in power and torque for Stage V. The 3.8-litre moves from 97 kW (130 hp) at Stage IV to 129 kW (173 hp) at Stage V, while the 4.5-litre engine jumps from 129 kW (173 hp) to 149 kW (200 hp). Peak torque of the F3.8 increases by more than 20 percent, to 620 Nm, and an 11 percent increase moves the B4.5 up to 780 Nm.

Electrify Intermat Paris
Cummins has announced that the company will show an electrified powertrain concept suitable for off-highway applications at Intermat Paris, April 23-28. A range extended electric vehicle driveline (REEV) will be displayed on Cummins stand F021 in hall 5A for the first time.
Cummins REEV combines battery power with a compact engine-generator, using a 4-cylinder Stage V F3.8 engine. It is designed to replace a standard driveline using larger Cummins or competitive diesel engines up to 9 litres capacity for applications from wheeled loaders to mobile cranes, terminal tractors to excavators. The system uses a high-efficiency traction motor providing continuous torque of 1,850 Nm, eliminating the need for gear shifting and dramatically reducing powertrain noise. An instant peak torque boost up to 3400 Nm is available when the machine hits difficult working conditions.
“We are expanding Cummins portfolio of products to reflect the alternative power needs of the future. We’re developing a range of options such as alternative fuels, range extenders and full electric power to complement our Stage V clean diesels and provide customers with the best solution for their machines,” said Hugh Foden, Executive Director Off-Highway Business.
The REEV system’s electronic control logic blends the energy use between the engine-generator and battery to best suit the operational needs. The engine-generator will automatically recharge the battery pack as needed. Operators will also have the option for overnight charging with plug-in capability.
“The variation in off-highway applications means that it is not one-size fits all. Our concept is modular so that it could be applied to a variety of equipment and offer the same range and operation as today, yet deliver significant improvements in efficiency and emissions,” added Foden.
The modular design allows the system to be aligned with the capability and duty cycle of the machinery. The high-density battery enclosure and engine can be sized to deliver the best balance between ultra-low emission and zero emission operation.
“Our REEV concept will be viable for emerging opportunities where even lower emissions are required to improve air quality, particularly in urban and port side locations,” concluded Foden.
