    just an idea: 2 stroke operation with reed valve crankcase induction and exhaust in the cylinder head.
    the rotary valve ports could be angled to be 'pushed' around by the impinging exhaust gas pressure; in
    effect a 'compound' engine configuration. the rotary valve could possibly have multiple ports, resembling
    a turbine, putting power into the crankshaft, geared to it with the suitable ratio.
    2 stroke cycle operation would resolve lubrication problems (if any) but 4 stroking could also be possible.
    I 'feel' your rotary valve architecture offers favourable timing possibilities for timing variations for c. e.
    operation. I haven't got the time to fully investigate this idea by 'gedanken' experiment for possible snags
    and being computer 'semiliterate' I can't post pictures or drawings but I have not overlooked the main point
    of your design; the absence of pressure on the valve. so far the full combustion pressure on the valve negated
    all the other r. v. configurations I have noticed.
