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 ...

Warped Perception — a channel dedicated to putting a fun spin on science, engineering, and technology — has been known to feature miniature engines to give viewers a better understanding of how the ...

This is what it takes to maintain a 9,000-rpm racing engine.

Rotary engines are already known for their high RPM; the smaller they get, the higher they tend to rev. So what happens when the world’s smallest rotary engine gets put to the test? Well, 30,000 RPM ...

The rotary engine, a unique and unconventional design, has provided Mazda with remarkable advantages in the world of racing.

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, ...

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 ...

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 ...

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 ...

Language is an imperfect medium, but it's what we've got, so let's go with it. Determining the swept volume of inventor Felix Wankel's rotary engine can generate more arguments than claiming what a GT ...

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 ...
