What do i see here is
1-A fully working . internal combustion engine.
3- Full complete toque.
4- Split cycle
5- Small size, light weight .
7- No oil or minimal oil.
9- basic ignition, not with ECU, that would be a great benefit.
Please note how easy this Russian was able to make this engine a true working one, when this design is as old as engine.
can you imagine if such technology world wide?
