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 ...

Designed and championed by self-taught engineer Felix Wankel, the rotary engine is now most closely associated with Japanese automaker Mazda. Many of the greatest Mazdas ever made, including the RX-7 ...

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 ...

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 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 ...

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 ...

Thomas has spent two years working in the auto journalism industry, contributing to a UK-based newspaper and writing for Euronewsweek. A full-time writer and lifelong engineering enthusiast, he now ...

The Mazda RX-7 is the sports car that made the rotary engine cool. Like really, really cool. It powered the RX-7 for 24 years ...

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 ...
