Off highway with Cummins X15 engine

February 28, 2025 Read time: 1 min
The X15 engine from Cummins can use clean diesel, natural gas, renewable biofuels or hydrogen to ensure compatibility with evolving environmental regulations

Cummins  Next Generation X15 engine for off-highway applications is a scaled model of the QSK60 engine for mining.

The X15 powers applications such as large construction bulldozers, cranes and excavators and is part of the Cummins HELM fuel agnostic engine platform. The platform’s new power solutions can use clean diesel, natural gas, renewable biofuels or hydrogen to ensure compatibility with evolving environmental regulations while supporting customer requirements during the energy transition.

The X15 will offer digital connectivity features, improved fuel economy and longer service intervals from its predecessor - all in a smaller package similar to that of a 13 litre engine. Ratings for the X15 will be up to 522kW and a peak torque of 3200Nm, targeted for Stage V emissions and beyond.

    Caterpillar’s seventh generation 988 wheeled loader – the 988K – is powered by a Tier 4 Final/Stage IV Cat C18 ACERT diesel engine, featuring selective catalytic reduction and delivering 362kW. The engine is said to deliver a 20% fuel efficiency benefit compared to the 988H, thanks in part to an ECO mode with on-demand throttle, auto idle and engine idle kickdown/auto resume system. The 50tonne machine moves away from its predecessor’s monoboom loader arm design in favour of a Z-bar linkage.
