The internal combustion engine, for all its mechanical sophistication, still runs on a 19th-century mechanical idea: pistons ...

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 ...

It's the stuff of legend: goggles, leathercaps, and fluttering white scarves, brightly-colored canvas-and-wood aircraft clashing in battle, just barely past the fledgling stage of human flight. The ...

It's as crazy as it sounds. Rolls Royce developed a diesel rotary engine for military applications. Because diesel engines ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

A German engineer, Felix Wankel, is credited with developing the world's first rotary engine in the 1950s. Wankel rotary engines use a triangular rotor spinning in a semi-oval case on an eccentric ...

How the 13B-MSP Renesis evolved from earlier Mazda rotary designs, technical features explained, and common problems and maintenance issues discussed. The 13B-MSP Renesis rotary engine powered the ...

In a world dominated by pistons, the rotary engine was something different for motorists. It was the vision of German engineer Felix Wankel, built on the belief that the up-and-down motion of pistons ...

A bold collaboration aimed to bring research to reality could rewrite the rulebook on sustainable energy. Advanced Innovative Engineering (AIE), the leader in high-performance rotary engines, is ...

Does anyone else think the Mazda RX-8 used to be the coolest thing on the road. It didn’t matter that it wasn’t that fast. Nor that its rotary engine burns oil like Snoop burns “za,” and slurps gas ...

Perfectly tuning the heat range of an engine's spark plugs is something of a dark art to all but the most well versed tuners and the engineering egg heads at automotive OEMs. Getting the spark plug ...
