Here’s a 4 stroke engine concept you have to see to understand, the Peraves Superballmotor uses a multipart sphere to replace the usual crankshaft, rods and pistons of a normal internal combustion engine.
The moving parts of the sphere have ceramic balls on their exterior which travel in grooves in the case surrounding the sphere. The rotating motion of the sphere causes the moving parts, which serve as pistons, to go through the 4 stroke cycle in 2 working chambers, which would be comparable to a 2 cylinder engine. Air and fuel are introduced at the sides near the rotating axis, are supercharged through the use of prechambers, flow into the gaps in the sphere created by the motion of the sphere, followed by compression, power and exhaust as you would expect. You have to watch the animation on their site to see the whole process because a description doesn’t work very well.
