Super-compact internally rotating combustion engine packs a solid punch




Take the trouble to figure this out.  I am sure that a viable target market exists although this is rigged for drones and big drones at that.  small can work with air cooling and that flat head could allow water or oil cooling without been a weight pig.

Definitely a contender for hybrids.  Again heat management is always the engineering choke point.

Actually good news as it is a promising tech that loses a lot of the weight of conventional.  Larger may well be good for diesel.  They need to try that on to see what is plausible for heat management.

Super-compact internally rotating combustion engine packs a solid punch

An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally rotating piston and sleeve arrangement, making it lighter, simpler and more efficient while still making strong power and torque.


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 development.


Rotary might be a good name for this sort of engine, if the name wasn't already taken. Everything inside the crankcase rotates, but unlike a Wankel-style rotary engine, this design uses a piston with two connecting rods that have a scissor-like movement attached to pinion gears at the back of the engine.

All of this rotates on a fixed ring gear connected directly to the output shaft. It uses a valve disk that also rotates to complete a four-stroke cycle of intake, compression, combustion, and exhaust as everything rotates internally.

It's dizzying. Check it out:
