With all the recent emphasis on electric vehicles, we often overlook the technology that still powers most cars on the road today. The internal combustion engine (ICE) has been at the heart of the ...

Small, ultra-fast, primary and “afterburner” secondary combustion events promise to deliver brake thermal efficiency as high as 69 percent. A better mousetrap? Even now, as electrification seems ...

Geely's new hybrid engine achieves record 48.41% thermal efficiency and 106 MPG, approaching Formula 1 performance levels.

During a seminar focused on hydrogen-powered internal combustion engines (H2 ICE), Volvo, Bosch, Cummins, and Cespira executives highlighted the work their companies are doing to advance H2 ICE ...

From heavy-duty trucks and agricultural machinery to shipping fleets, aviation, and power generation, internal combustion engines STILL remain indispensable to both global infrastructure and mobility.

The rise to power of electrified powertrains had some believe, for a short while, that internal combustion engines (ICE) were done. To some extent, meaning the medium-term evolution of the automotive ...

The short answer is yes: innovative internal combustion engines, especially in combination with batteries, can and will play a crucial role in decarbonizing aviation for small aircraft, urban air ...

As the fuel burns, it ablates, leaving a fresh layer of fuel to feed the flight. By not carrying oxygen, the engine is not only lighter, but it's more efficient. Where a solid fuel rocket has a ...

Forbes contributors publish independent expert analyses and insights. I am a professor at Cal State LA and the technical director for the Hydrogen Research and Fueling Facility. We go for better ...

Despite its critics and moves toward electrification, the internal combustion engine is not yet dead. Though its design for passenger vehicles may have begun to reach its apex with Mazda’s Skyactiv ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...
