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 ...

In this fascinating video, we journey through the intricate process of building a rotary valve engine from scratch. Watch as we delve into the mechanics and craftsmanship involved, showcasing each ...

It’s a dedicated hacker who has the patience to build an engine from scratch. And it’s a borderline obsessed hacker who does it twice. [Meanwhile In the Garage] is of the second ilk, and in the video ...

Many of you have seen the process of making this rotary valve engine with different intake and exhaust system and how I tried to start it. After so many attempts to start this engine, I was ready to ...

That alone reduces emissions and increases engine longevity. The rotary valve also means that the blockages caused by conventional poppet valves are not an issue as poppet valves are not needed in ...

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 ...

WEST LAFAYETTE, Ind. — Researchers in Purdue University’s College of Engineering are testing a patented Tesla valve-inspired injection manifold design that could improve the performance of rotating ...

While modern engines feature many tweaks and improvements on the original ideas, they usually aren't as interesting as the strange contraptions engineers experimented with in the early days. Take, for ...

Researchers at Purdue University's College of Engineering are conducting tests on a patented Tesla valve-inspired injection manifold design to improve the efficiency of rotating detonation engines ...
