  1. 0.1mm tolerance is nothing to write home about. Valve clearance of my bike, IE, has to be between 0.15mm and 0.20mm, so with a tolerance of 0.05mm, and it's not anything "racing". That doesn't mean this is, to me, a viable product. I see many sealing problems. Compressed air and air/fuel mixture simply has too many passages to do, and having, like in the Wankel, a "hot" and a "cold" part of the engine, worsens sealing problems. Liquid Piston engine doesn't seem a to have anything wrong actually.

  2. It seems to be made for diesels. There the speed problem is greatly reduced, since diesels can't rev high anyway, due to the time required for diesel fuel to burn. Diesel combustion is colder than gasoline one (higher decompression of gasses cools them), direct injection works better for diesels than for gasoline engines, and blow by is less of a problem.
