Despite its critics and moves toward electrification, the internal combustion engine is not yet dead. Though its design for ...

If you never knew that Geely made the internal combustion engine (ICE) with the world's highest thermal efficiency, do not feel guilty. I tried to let people know about it in August 2022, when the ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

The H12 is supposedly a variant of the HR12, a 1.2-liter, three-cylinder turbocharged engine, which was fitted with a new combustion system with a 17:1 compression ratio, a new exhaust gas ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

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 ...

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 ...
