The neat thing about my engine

There are two moving parts, the wheel hub and the combustion  piston. Everything in between is electronic controlled magnetic and current. The combustion force can be as big as any other engine.  But the piston cylinders can be arranged and re-arrange at will, since none of them are mechanically connected, except for cooling. No reason it can;t work.  It is important as a reference design, as it gives the net cost of the combustion facility, by itself.  The cost for a small four cylinder is less than 200 pounds, I am sure. Need to tie up that boundary condition.
