This is the kind of thinking we need..... it was a 'what if' that led Felix Wankel to invent the original Wankel engine (which is NOT like the Mazda configuration) all these years ago. I hadn't thought of using a cross slide linkage to give the rotor this motion before.... so clever! I am not really a fan of Liquid Piston's config, as I think it is too hard to manufacture. Mr. Kudryashov has come up with a clever configuration here.
Clever idea. A lot better combustion chamber than Wankel but same problem of having to put ring lubrication in with fuel source. Also same problem of large surface area combustion chamber losing a lot of heat. I would have piston valves on outside circumference as it looks like I think you can have 2 power stroke in a row then 2 inlet strokes in a row etc. Better scavenging than porting. You don't need cross slide linkage as can use eccentric gear drive same as Wankel.
The torque arm [lever] is just barely longer than the arm [lever] on the other section of the rotor = wasted energy. We have patented a number of pure rotary engines based of the four bar linkage which is the strongest mechanism possible.
Either this isn't a two stroke or it is missing an ignition step. Also, the cross slide linkage will generate large amounts of friction. It is an interesting idea, but I think the cross slide linkage fundamentally makes it impractical.
Agree with your latter point; the internal surfaces used to guide the rotor are too small in surface area work, I think. Also, this design has the same flaw as the Wankel, that it has sliding surfaces which require oil but which are fully exposed to combustion and carbon deposits and high heat. Also there are the unhappy/overworked apex seals that don't get enough oil and have too much wear. Ideally, we need a rotor that wobbles in the housing without actually turning, like a reciprocating piston engine does, so sliding surfaces lubricate themselves and are mostly not exposed to combustion and combustion areas .

I think its will be better with transfer port between the side housing, But small size.

The engine has very little torque output during its power stroke just like Wankle so forget it.
Low torque as an Wankel engine
