Considering the little space left free, a tool would not fit and the molding would be too complex. MYT and Russian are in two half-shell. Either way, that would not solve the leakage problems which are the number one enemy of high compression engines. The classic piston engine ...

As precise as machining can be, it is within tolerances necessary for its execution and the tighter the tolerances, the more expensive it is. So the execution tolerances of the strand, of the flanges, of the casing, mean that each machining is added to the others with as many lines of fu ...

The major problem with these motors comes from the machining of the half strands and their final assembly, as well as the piston support flanges, the sealing of which is a serious technological challenge. It does not seem that neither the MYT nor the ROTOBLOCK worked in thermal mode, nor the QU ...

And then there is Charal whose video is not very econologist.
