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 ...

Rotary engines, known for their unique design and compact size, have been predominantly associated with Mazda. However, engineers and automotive enthusiasts have experimented with incorporating these ...

The Wankel rotary engine offers one of the most unique sounds of any ICE. Most famously used in various legendary Mazdas like the RX-7 and the supposedly banned Le ...

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 ...

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 ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

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 ...

Since the development of the internal combustion engine, humanity has long pursued the common goal to make them run as fast as possible. And whether it's gasoline-powered engineering marvels like ...

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 ...

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 ...

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 ...
