Global power and technology company Cummins has announced a new mining engine that "sets a new benchmark for mining power" by offering innovations in fuel economy, reliability and power density.

Having unveiled the Cummins S29 mining engine at an event in China at the end of October, Cummins power systems VP Jenny Bush said the engine ensures exceptional performance, exceptional total cost of ownership and the flexibility to adapt as mining operations evolve.

Customers can see the S29 engine on display during Asia's premier international trade fair "bauma CHINA" from November 23 to 27 in Shanghai.

The 29-l engine is designed for 90-t to 120-t haul trucks and 150-t to 220-t excavators, with additional applicability across a range of mining and industrial equipment, including surface miners, bulldozers, wheel loaders and dewatering pumps.

The engine is planned to be available globally from late 2027 in regions that require China Stage III emissions configurations, equivalent to US Environmental Protection Agency Tier 2 requirements.

"The S29 is designed to deliver competitive power density with output of up to 1 300 hp at 2 100 rpm, which enables maximum vehicle integration flexibility, with the S29 delivering the power and performance of higher displacement engines within a compact installation package. 

"Additionally, based on current development targets, the S29 is expected to achieve fuel efficiencies of 180 g/kWh, which represents industry-leading fuel economy for its power range," Bush explains.

She adds that the S29's fuel-agnostic capability will help customers support evolving fuel strategies. At launch, the engine is planned to be compatible with diesel, unblended paraffinic fuels such as heavy fuel oil and biodiesel blends up to B50.

The engine's fuel capability is also being designed to support potential future natural gas, hydrogen or duel-fuel configurations.

Further, the engine will be well suited for extreme environments of high altitude and temperatures.

"Mining customers are under relentless pressure to move more material, lower operating costs and improve efficiency. We are excited to provide the next generation of mining power with the S29 - a truly world-class platform purpose-built to help turn those pressures into more productive and profitable operations," says Cummins industrial markets for power systems VP Gbile Adewunmi.
