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 ...

Almost every internal combustion vehicle on the planet today uses the classic piston engine. These run by converting heat energy into reciprocating motion, and then rotary motion that ultimately ...

In theory, Wankel-style rotary internal combustion engines have many advantages: they ditch the cumbersome crankcase and piston design, replacing it with a simple, single-chamber design and a thick, ...

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 ...

The traditional piston engine has garnered the vast majority of attention and application in the internal combustion age, but there was another: the Wankel rotary engine. German engineer Felix Wankel ...

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 ...

Michael Arsenaeu designed the Avadi engine 20 years ago in the hopes of creating an entirely new engine design to be efficient as well as reduce emissions. In 2015, Avadi began the build and ...

Alina has been enthusiastic about vehicles her entire life, and even from an early age found herself itching to get behind the wheel. Through high school and college, she could be found reading ...

Everything about this build is pure comedy, and you’ll soon see why. Things start funny, with the builder employing a three-door, second-generation Toyota RAV4 as its blank canvas. Not only does that ...
