Libralato Engine
The Libralato engine is potentially the best small engine in the world; an eco-engine for the 21st century. The asymmetrical rotary engine is exceptionally compact, powerful, efficient, low emissions, low production and maintenance costs, low vibration and low noise. The engine is ideally suited for use as an onboard generator for the next generation of Range Extended Electric Vehicles (REEV) currently being developed by major manufacturers around the world, but is also suited for a wide range of mobile generator sets and other small engine applications.

nice try, but how you garantee the wear of the cylinder wall does 200.000 miles?
you wasted your time.
by the way, if you did your research right you would have found out that the spark plugs is soon to be replaced.
Very innovative …
Very innovative design. It would be cool to see it succeed in practice. Others already posted, and I agree sealing all those interfaces and oil contamination could be a problem, but it could also be on a standard piston and that was largely resolved with piston ring technology and materials.
It would be cool to see a working prototype. Good luck!
Very interesting …
Very interesting design. I see two problems tho, (i) Sealing the sliding contacts between the two rotors (ii) Oil mixing with incoming air
very interesting, …
very interesting, looks great
I was going on the …
I was going on the advice given by an uncle of mine who was involved in local dirt track racing back in the 60’s. Very powerful, but had sealing problems. Plus, in hi-perf engines which run rich, soot buildup and resultant abrasion of the seals were the main problems. But, if these can be overcome that would be great!
Rotary valves were …
Rotary valves were never officially used in the motorsport field. They were to be used in F1, but the FIA changed the rules.
Tests conducted on V10 F1 engines proved that the rotary valve was actually more robust than conventional poppet valves and improved power by 10%. I have a document somewhere with all the info.
so many seals at …
so many seals at high speed? Also rotary valves were used in racing with limited success, potent flow but low durability. Great job on taking initiative and actually making a prototype!
Very interesting. …
Very interesting. Show it working.
Looks interesting.. …
Looks interesting.. But 3 atmospheres is not much, at sea level its about 14PSI so 42PSI of compression??? most piston engines are 120-190PSI. So it will not be efficient combustion. Rotaries have the same trouble.. low thermal effieciency, but very high volumetric efficiency… I like the idea of this engine, but it seems to has all the negatives of a rotary, and has more moving parts too. I could be wrong.. I would like to see it run.
looks kool and …
looks kool and should make good power have you got a working one
his is NOT a wankel …
his is NOT a wankel engine!!! The wankel engine is different…
I don’t quite …
I don’t quite understand how it works but looks nice. would be nice to see all the parts taken out
more moving parts, …
more moving parts, more to go wrong
its actually a lot …
its actually a lot different although it is in a similar shaped block
this is a wankel …
this is a wankel rotary engine used in the mazda are you reinventing the wheel?
i think that not …
i think that not all combusted air was released,
it will not pass on euro emission standards..??
i guess?????????
nice
nice
love it, lets see …
love it, lets see it run!
wow looks cool…
…
wow looks cool…
had it running yet??
So what. Too many …
So what. Too many moving parts. Lubrication problems. Pollution problems. Won’t last long before it wears out completely.
I figure the …
I figure the lubrication would probably be dry-sump.
I have to admit this is one of the most elegant designes I’ve ever seen. I can’t wait to see the test results.
i would like to see …
i would like to see this run off propane
i was thinking ” …
i was thinking “sluterry” that maybe he was thinking of using oil in the fuel kinda like a two stroke engine, but the engine is not design like one, so yeah try putting lube in the fuel
WANKEL !!
WANKEL !!
i fail to see this …
i fail to see this engine lasting long as there is major flaw LUBRICATION this engine will either burn allot of fuel and therefore fail to meet emissions standards or have no resistance to friction once at running temp (i realise he says it decreases friction though lets face it its metal on metal and throw in high temp and theres ya friction) although kudos to the engineer it is quite clever
