ABSTRACT:
A rotating-liquid piston engine having two or more cylinders that are partially filled with a fixed volume of liquid and are interconnected by two tangentially-connected, unidirectional flow tubes or pipes containing hydromotors. For an internal combustion engine, each of these cylinders has a top and bottom cover and a system for intake of fuel and air and an associated exhaust system. Each cylinder may have either an electric spark plug or work in a diesel mode (via an injector). The liquid in each cylinder is caused to rotate in a circle around the cylinder wall at high speed and create a vortical liquid body with a cylindrical cavity in the middle of the liquid. Rotation is used to totally stabilize the working surface of the cylindrical cavity whose surface is the "top" of the rotating-liquid piston. This cavity is the combustion chamber into which the mixture of fuel and air is injected. When the fuel mixture is burned, pressure in the cavity inside the rotating-liquid causes some of the liquid to be pushed out through a tangential outlet tube, through a hydromotor into the inlet of the second cylinder (where this cycle is repeated) and liquid flows back into the first cylinder again. In this manner, fluid is transferred back and forth between the two cylinders at some variable frequency, as a result of the pressure from combustion.
