Hi. Thank you for your interest in the project. Those are many questions you have. The basic "idea" , which could not be fine tuned in any way without advanced software, was to use an electric supercharger to generate hi boost on a small engine. The prototype I hold in my hand is only about the size of a lunch box and it creates a single 330cc chamber with intakes the size of ping pong balls. mega boost on a 5Litre engine is no easy task, but much easier on 330cc with large ports. The hope was to use the pressurized air to cool the parts, seal the gaps, and provide compression. the only lubricant would be internal to the rotors' bearings and in the gearbox of course. Direct injection is preferred. My main focus was to keep things spinning true, use air for multiple purposes.. (just like NASA uses fuel to cool the engines before it uses fuel to fire them) and eliminate seals. I can not be sure the rotors will make efficient use of the flame wave as it moves from ignition point to exhaust point. The design was fun to make! I know I don't have any engineering background and can not answer all your questions. "Not bad for a musician" though, right? That seems to be the best answer I can get on it. Haha. Somthing about it "Makes good music". It is balanced, harmonious... and shiny! :-P
