Now it is looking closer at new technologies, notably electrics.
Cummins is considering partnerships in developing “advanced technology” in power electronics, energy storage and traction motor systems.
And in 2019 it will begin delivering electrified powertrains including battery-electric and plug-in hybrids.
“As a global power leader for commercial and industrial markets, we are well-positioned to win in the new and emerging technologies sphere,” says Tom Linebarger, chairman and chief executive.
“Over the last 100 years our ability to innovate and adapt has fuelled our success and we are preparing to provide a range of technologies from diesel and natural gas to fully electric and hybrid solutions.”
It envisions zero-emission natural gas being a strong alternative to current offerings.
Other projects include a high-efficiency petrol engine said to have diesel-like durability and performance, and hydrogen, bio-fuel and synthetic fuels.
Cummins blue-skies ideas include proton exchange membranes and solid oxide fuel cells.
