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 ...

While modern engines feature many tweaks and improvements on the original ideas, they usually aren't as interesting as the strange contraptions engineers experimented with in the early days. Take, for ...

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 ...

A Wankel engine is a type of rotary engine, but not all rotary engines are Wankel engines. Wrapping your mind around this idea will help you to better understand the similarities as well as the ...

Not every engine has a set of pistons that move up and down in a cylinder. The Wankel, or rotary engine, delivers its power with rotational force rather than a reciprocating mass that hammers out ...
