  • Publication number: 20160201464
    Abstract: An intake/outlet pipe optimization method includes the steps of providing a rotary engine, measuring the pressure in an operation of the engine, designing the appearance of the intake/outlet pipes, adjusting the pressure wave in an air pipe and the pressure in an air chamber of the engine to increase the air intake and improve the output horsepower of the engine. The intake pipe is a tapered pipe having the pipe diameter on an intake side greater than the pipe diameter on the engine side; and the outlet pipe is an inversely tapered pipe having the pipe diameter on the engine side smaller than the pipe diameter on the outlet side.

  • Patent number: 9322328
    Abstract: An internal cooling passage structure for rotary engine, which includes a rotary engine body, having a front frame, a mid-frame, a rear frame and a rotor, wherein the rotor has cooling passages beneath the rotor triangular apexes, and both front and rear frames respectively have corresponding openings; a rotor, rotating in the mid-frame, having the core cooling passages in full or partial connection with the openings in both front and rear frames in the engine operation; and a guide vane along the opening edge, wherein external air is guided into the rotor core cooling passages by the guide vane which avoids generating heat vortices and helps to increase the cooling air so as to lower the temperature on the rotor and its assemblies.
