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

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 ...

Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...

For more than 100 years, the internal combustion engine (ICE) has been the mechanism of choice for vehicles of all shapes and sizes. Across all configurations, the principle is the same: a mix of fuel ...

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 ...
