In this video we analyze the new engine from the Avadi company that uses 2 connecting rods and rotates. Basically, this system integrates a reduction in rpm and increases torque, creating an engine worthy of analysis.

Huge thumbs up to them building a working prototype and making a video of the engine running! That already sets them apart from 99% of the other "innovative" engine designs.
-
No, it’s a 4 stoke , one rotation engine. A rotation and a stroke is not the same thing, has never been the same thing, and will never ever be the same thing 🤦♂️
-
The side pins that are connected to the gears are submited to great forces, by being supported on only one side, the bushing/ bearing will fail fast.
-
I think the age old problem with all engines with sliding type valves will be sealing the ports properly when they're closed.
-
Lets crank the friction WAAAY UP for...some reason.
-
Any time someone says an engine part is subject to "no wear" they are immidiately wrong. It might not wear "much" but it will in fact wear down
-
There is a lot of rotating mass per cylinder compared to a traditional engine, with additional losses through the gears. In addition the head design seems limiting. It is good to see innovation but it is unlikely this engine will be more efficient than a conventional piston engine.
-
It's relaxing to watch these videos. However, with more moving parts, it may be more unreliable than a conventional engine Edit: the compression stage will force a load onto the piston, which will be transfered to the connecting rods. The resulting opposing forces are not completely canceled out, as they are a perpendicular distance apart. This forms a rocking couple which tries to rotate the piston from the top and twist the connecting rods, putting a lot of physical torsion on them.
-
So at half way in the video you make it seem like the engine is way better than a traditional engine in terms of performance but later down the line you say that the engine is actually at a 2:1 gear ratio by default so its actually the same. Honestly I don't expect these engines to make it to the market because the seals are probably not going to be able to withstand the harsh conditions as well as poppet valves can
-
First thing I notice when I look at it are the straight-cut bevel gears. How much do I believe in its longevity and reliability, and why "not at all" is the correct answer?

looks like a diving arm bread mixer

This is the first video of yours I've came across, but I'm impressed and now subscribed 👍 Really fascinating engine concept...
-
Interesting! We tend to see a lot of new engine design ideas and most of them kind of peter out. I hope this one does better. There are myriad uses for a small, light engine. Generators, personal watercraft, scooters, Jaws of Life, emergency water pumps for flooded areas, leaf blowers, air compressors and other shop equipment.

Actually the piston does indeed rotate. Just because the cylinder rotates with it does not mean it is no longer rotating it is just that the cylinder rotates with the piston. I don't see how this extra rotational force could defeat the standard piston engine of the same caliber. Sometimes less is more.
-
It is interesting but another concern I would have is that the centrifugal force generated by a spinning cylinder may tend to cause liquid fuel to cling to the cylinder wall. Not as much of an issue with NG or H2 but it would be better if the same type of force could be used to do the opposite and tend to force liquid fuel away from the cylinder/combustion chamber walls.
-
Lot of friction losses. A stroke isn't a rotation btw.
-
I can see the top ends of the rods producing a twisting force on the gudgeon pin 😮
-
I always love to see different solutions for an problem (in this case creating torque out of fuel).🤩 Some pretty mind blowing concept, complex but rather simple at the same time. I wonder if a diesel version would be possible? 🤔

This engine can easily be turned into a 2-cylinder opposite one by combining 2 1-cylinder engines
