When considering rotary engines, the Wankel engine often comes to mind due to its high power-to-weight ratio, though it suffers from drawbacks in fuel economy, emissions, and durability. In contrast, ...

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 ...

Do you know the difference between a four-cylinder, V6, and V8 engine? Quick hint: it’s not just about size. It’s about how much force each one can make, how much fuel they need, and what kind of ...

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 ...

Reports of the death of the internal combustion engine have been exaggerated. Electric vehicles were once poised to diminish the ubiquity of traditional engines, but automakers are booking huge losses ...
