Light weight and cheap to manufacture, can be made from mono-block as no valves to deal with. Vibration can be an issue if it is not desired (motorcycle…) but can be dealt with by having a twin running on opposite cycle. Can be configured in line (serial), two or more side by side (parallel) or horizontal boxer. Right triangle configuration of three duality’s (six cylinder) at 120° to each other with either exhaust or intake port in center is another option. Spark can be generated form magneto or capacitor discharge ignition. Electric linear actuator (helenoid, colenoid) can be used to start or cheap and simple mechanical setup like hair-clipper/grass mowers. If interdependently operated it can run in “eco mode” with only two of four/six/eight... cylinders operating with driver going across town in city traffic and the other(s) started up when more power is required. Differential or drive shaft is not needed as air or liquid can be used for propulsion and turn the wheels. Will see if I find a model engine engineer to make a working model. The duality (yin-yang, husband and wife, whatever you like to call it) engine is a dream for every mechanical engineer as lots of configuration, uses, fuel types or sizes are at hand to utilize.

Some repositioning of cylinders to have it at different stroke position. There is no real need for spark plug and ignition system either as rocking/working arm can be long and heavy enough with the right angle to produce sufficient pressure to auto-ignite most fuels. Diesel, Jet fuel, Kerosene 210°C, Petrol 246 – 280°C, Heating oil 256°C, Gun Powder 288°C Ethanol 363°C ….

It's an interesting design. :-) Would be fun to get feedback from professionals, and to see a 3D animation of it. The bottom half seems to have room for improvement. For example the component number 4 at its current position would perhaps benefit of having the container shaped like in this picture.

Yes it is radical new, nothing is turning. Not turning complete. Completely doing away with the inefficient rotational movement, bearings the only wheels. The drawing is rough on all edges, the rod not even in center of cylinder, its a basic sketch. The beauty of it , it is a totally blank sheet lots of possible ways and every way of doing it must be started new. 3D animation is first step, only a matter of time some animator will produce a model. Professional feedback, something to look forward to.

As a matter of fact, no need for ball bearings, sleeve (bushings/plain) bearings will do just fine.
