  • Muffler and catalytic converters for combined heating and power systems
    Patent number: 11352930
    Abstract: A combined heating and power system is configured to generate energy as well capture a large percentage of energy that would otherwise be lost using components, including heat transfer components, embedded within a vessel to transfer energy in the form of heat to liquid within the vessel.
    Type: Grant
    Filed: February 20, 2020
    Date of Patent: June 7, 2022
    Inventors: James Warren, Gregory Powell, William V Meyers, Jr., Richard Steven Niswander, Mark Helmut Dorner, Noah Alexander Hopson, Jack Lawrence Jerovsek
  • Fuel ignition methods for opposed piston engines and related structures
    Patent number: 10989109
    Abstract: Fuel is ignited in an opposed-piston engine by the mating of unique protruding and recessed portions of opposed pistons.
    Type: Grant
    Filed: July 17, 2019
    Date of Patent: April 27, 2021
    Inventors: James Warren, William Vincent Meyers, Jr., Steven Niswander
  • Methods and devices for controlling the compression ratio of an opposed piston engine
    Patent number: 10907515
    Abstract: A valve with an opening is driven by an electric motor to rotate around the cylinder of an opposed piston engine such that the opening separately matches an intake and exhaust opening on the cylinder to allow fuel to enter the combustion chamber of the engine and allow exhaust to be expelled. The intake and exhaust cylinder openings may be separated from each other by approximately sixty degrees of the outside of the cylinder.
