ABSTRACT:
A charge cooled rotary engine includes a housing, a first end plate, and a second end plate. The housing and end plates combine too define a closed chamber. A rotor disposed within the housing includes three flanks, a cylindrical hub, and a web extending transversely from the hub and joining medial portions of the flanks to the hub. The web, flanks, and hub form rotor cavities on opposite ends of the rotor. Inlets formed in the end plates for receiving fuel/air charge terminate in entry ports facing the closed chamber. Distribution chambers, formed in the end plates adjacent the entry ports, are open to the closed chamber. The entry ports directly communicate with the rotor cavities and are isolated from direct communication with any of the intake, compression, and combustion chambers by the rotor flanks. The distribution chambers variously communicate directly with the entry ports via the rotor cavities subject to partial obstruction by the hub and variously communicate directly with the intake chamber subject to obstruction by the rotor flanks. Heat transfer devices are provided in the fuel/air charge, and a novel fluid lubrication means lubricates all bearings and seal.
