Next gen X15 to play key role in the great energy transition
Cummins’ industrial appeal is broader than ever
Cummins’ next generation X15 engine is set to play a pivotal role in the transition to clean energy for customers operating in the Off-Highway and Mining sectors.
The X15, which will be centre stage at the Bauma trade fair in Munich, powers heavy duty applications such as large bulldozers, cranes and excavators.
It is part of the Cummins HELM™ fuel-agnostic engine platform, which means it can utilise natural gas, renewable biofuels, such as HVO and biomethane, or hydrogen.
The Next Gen X15 for Off-Highway offers ratings up to 522 kW (700 hp) and a peak torque of 3200 Nm (2360 ft lb) targeted for Stage V emissions and beyond.
The hydrogen X15 has ratings up to 395kW (530 hp) and natural gas up to 380 kW (510 hp). The advanced diesel version can use either HVO or biodiesel with ratings up to 485 kW (650 hp) for the most demanding off-highway duty-cycles.
Thanks to its advanced XPI fuel system, which enables precise injection and optimised combustion, fuel consumption of the X15 is as low as 180 g/kWh, reducing total cost of ownership (TCO) and lifetime CO2 emissions.
The Single-Module™ Aftertreatment System reduces emissions and simplifies maintenance. The X15 has extended maintenance intervals up to 1,000 hours, cutting service costs and downtime.
Visitors to Bauma will see that after a series of acquisitions, including Meritor, Cummins is now positioning itself as so much more than a manufacturer of engines: it is a supplier of premium integrated powertrain solutions, covering engines, a wide range of axles, heavy-duty brakes, transfer cares, gearboxes, aftertreatment, telematics and more.
Cummins’ power unit packages offer customers the ability to select the optimal combination of powertrain and components.
“We’re making record investments in our technologies and have one of the broadest portfolios of power solutions for industrial applications in the world,” said Marina Savelli, Vice President, Off-Highway at Cummins.
“Our versatility, scale and longevity position us to help OEMs succeed, and we’re thrilled for the opportunity to meet with many of them at Bauma.” Also on display at Bauma will be the Tier 4 Final/Stage V compliant Cummins QSK60, which delivers a maximum of 2125kW (2850hp) and a maximum torque of 11,218Nm.
Equipped with Cummins’ PrevenTech™ telematics-based diagnostics solution, the QSK60 provides more than 40,000 hours of operation before requiring an engine overhaul.
Making its debut at Bauma will be the Meritor MOX E8 telehandler axle, designed for durability and productivity. Engineered for the most demanding duty cycles and applications worldwide, Meritor axles are recognised as industry leaders.
In a further boost to its mining sector capability, Cummins recently acquired the assets of First Mode, a leader in retrofit hybrid solutions. The acquisition includes hydrogen and battery powertrain solutions.
First Mode’s technology represents the first commercially available retrofit hybrid system for mining equipment, significantly reducing TCO while advancing decarbonisation in operations.
“With hybrid retrofit kits, modular component upgrades and scalable solutions, Cummins is bringing miners the flexibility and confidence they need to decarbonise operations while adapting to evolving technologies and infrastructure,” said Jenny Bush, President of Power Systems at Cummins.
