It's as crazy as it sounds. Rolls Royce developed a diesel rotary engine for military applications. Because diesel engines require high compression ratios for compression ignition to occur, they used ...

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 ...

Chris Bruce has worked in the automotive industry since 2011 and has written thousands of stories about cars, motorsports, and motorcycles in that time. He has written for Autoblog, Autoviva, CarFax, ...

The engine in question was the Wankel rotary, named after German engineer Felix Wankel, who first patented the concept in 1929. Instead of pistons moving back and forth, the rotary engine used a ...
