I'm wondering how it's solving the valve sealing problem, there's a reason popits are still in use.

[@philoso377]

Nice video and presentation. One think that pop in my mind is that angular momentum in the twin gears wanted a stationary axis and not steered by the gear arrangement. The design must deal with eddy forces in the system to address extra stress, mass, friction, wear and efficiency penalty.

[@Iowa599]

That valve system is very similar to sleeve valves, like used in the Hurrican radial engine. It will burn oil.

[@MichianaFisherman]

Multi cylinder can be done on the other side and retrieve the power from between them?

[@horseblinderson4747]

Probably not in order for the head to spin properly so that the exhaust valve still functions the plug needs be centered. Putting a shaft out to top would make that impossible. Through they could go to the other side of the output shaft with a counter rotating piston. Butt that still only leaves you two pistons. However if reciprocal motion is the goal they could mount them in banks synchronized with a chain but use a rack and pinion to get that motion. But the only application I can imagine needing that much relatively short strokes at that much torque would maybe be an air compressor.

@@horseblinderson4747 Place 2 engines tail-to-tail shaft with one engine built to run the reverse of the other with both pistons reaching TDC simultaneously tho 180 degrees out cycle sync... (intake=0=power) (compression=0=exhaust) (power=0=intake) (exhaust=0=compression0

[@AndyRRR0791]

This has a lot in common with the RCV engine. I'm not sure the balancing advantages won't outweigh the torque that this concept applies to the conrods and their bearings.

[@jtuttle11]

Actually, In ANY reciprocating or Piston engine the speed of the reciprocating mass (Piston,connecting rod assembly) is constantly in a state of acceleration and deceleration. A property that is directly influenced by the 'Rod Ratio' (The length of the connection rod measured from wrist pin center to crankshaft journal center) Ideally this ratio is 1.9 (Rod Length) to 1 (crankshaft throw from top dead center to bottom dead center) As the crank rotates, the speed of the piston/rod assembly changes.

[@BrickEngines]

No they don’t balance each other out, there’s a rocking couple

[@BrickEngines]

For whoever is currently confused, I’m talking about this timestamp here: 4:43

[@AndyRRR0791]

and a large torsion on the conrod and bearings.

[@ThiagoMarquardt]

Center of mass still centralized

[@AndyRRR0791]

@@ThiagoMarquardt The thrust force of each conrod at the gudgeon pin is offset from the piston axis so will cause a torque that will be reacted by the conrod bearing edges. Also the counterweights are not coplanar so they will generate a rotating couple.

[@cedhome7945]

We were allways taught that you should never use equal numbers of gear teeth as wear increases, use unequal numbers

[@pashakdescilly7517]

Using the rotating cylinder to expose inlet and exhaust ports means that this is a version of sleeve valves. Are the ports in the upper cylinder wall or the end of the cylinder?

[@rawcado]

Too bad they didn't show that in the animation, we'll probably never know.

[@timothymcgovern7279]

A 50cc version would be ideal for a Chain-saw-greatsword. Get on it.

[@johncunningham4820]

The IDEA is excellent , but there will inevitably be big problems with Sealing on the Disc Valve system .

[@andrewgrillet5835]

And, with all those hot moving parts, hideous levels of wear all over the place.

[@311Bob]

Why not move the valve in the cylinder like 2 stroke? With the cylinder wall already rotating would seem an easy and timing sinch

[@robertmorris9275]

This design still has reciprocating mass, I know of a rotary design ( not the wankel as used in Mazda's ) having 90 degree firing sequence, massive torque at low RPM, only 5 moving parts. Just need recognition, the piston engine as we know it will be ancient history

[@josemathew9087]

Gear teeth may not withstand heavy dynamic forces for long period. Noice level will be high.

[@311Bob]

Not to be a smart ass but differential? Can take quite a pounding

[@ThiagoMarquardt]

Gear teeth may not withstand? I can't remember a case where a teeth failed in a gearbox with a lot more load

[@josemathew9087]

@@ThiagoMarquardt lmpact by power stroke act directly on crankshaft and resisted by inertia of crankshaft and flywheel. Hence impact on trasmission gears is diffused and not get damaged.

[@Iowa599]

Honda CBR250 makes more than twice the power than that does...

[@arthurgay5746]

Not enough moving parts !!!

[@gsestream]

single-axle boosted tesla turbine ice engine is much better. it uses external carburetor style burner and is boosted by tesla turbine intake and torque is generated in the same axle on a second tesla turbine stack. yep much simpler than normal axial turbine ice engines and better than wankel rotary ice engine. of course its not patented or patentable or locked down as anyone's ip.
