" it could work if you delete most friction "
It's not a matter of friction, but matter of principle. Is not it clear?
When piston goes down,  the "shield" covered the top magnet and reduced repulsion. And in the same time the spring of lever brakes the cam. Piston will stoped somewhere on the way down. Is not it so, Anatoliy?

I did measurements of forces on all a cycle of rotation of a shaft of the engine. Considered closing ferromagnetic screen. But useful job of rotation of a shaft is more than job spent on moving ferromagnetic screen. Tests spent and in movement. Job of a shaft all the same is more.
The given engine does not work only because the lever of a drive ferromagnetic screen is made badly, and there is no good coordination of movement. As will appear money, I shall complete this mechanism.
Yours faithfully, Anatoly

What kind of magnets U used for such heavy machine? And where's the spring? Inside of this small box?
"But useful job of rotation of a shaft is more than job spent on moving ferromagnetic screen".
-Wait a minute. Useful work per cycle is only when piston goes down, all other movements - lost energy. That's why U should to measure THIS move of repulsion to compare to  " screen" closing forces.
I thought it would be easy to make first more simple models.
Anyway - nice try, really very, very good job.

@wizkycho

permeable means it will attract, it conducts mag flux. both shields ATTRACT => net force at shaft near zero.

Yes, both shield attract, but at one shield the endmagnet oft the piston is closer to this shield than the other endmagnet to the other shield, so the net force at the shaft maybe is not zero. I mean, when the lower shield lift up it has to overcome the attraction both of the outer magnet and the endmagnet of the piston. At the same time the upper shield on the other side goes down and is only attracted by the outer magnet but not so much by the pistonmagnet, because its distance is greater then to the other shield. What do you think?

this is logical (but first look) thinking, nevertheless it still gives COP 2.

No, it will only work with an iron or steel shield.
But the question is, if the force attraction of the 2 magnets in
repellmode to the shield is stronger than the single magnet
wanting to pull the shield down at the other side...

Hmm, I unfortunately guess, that  the force is stronger to hold and keep the
shield at the repelling magnets side between these magnets there.

As the airgap is pretty big at the other end, where the single
magnet wants to attract the other shield, this force is probably smaller
and this way it will not work.

Otherwise if maybe 2 of the units would be synchronized and
phased maybe 90 degrees out of phase, maybe it will work then
