Abstract: A power system including a variable volume combustion chamber for a two-stroke engine having a controlled exhaust port, a fuel injector to the combustion chamber and an oxygen injector to the combustion chamber. The oxygen injector provides repeated oxygen injection pulses to complete a charge. The controlled exhaust port includes an oscillating rotatably mounted valve. A source of pressurized concentrated oxygen to the oxygen injector is in a closed case having a ceramic fiber membrane. An air inlet and a waste outlet are in communication with a first side of the ceramic fiber membrane. An oxygen outlet is in communication with a second side of the ceramic fiber Ionic transport membrane. The case has a heat transfer surface in communication with the controlled exhaust port from the combustion chamber.

Abstract: A vehicle engine brake comprising a vessel for the passage of gases having a main tube and a by-pass tube is provided. The by-pass tube defines a first opening into the main tube and a second opening into a more downstream location of the main tube. A first valve, to regulate the passage of gases through the main tube, is provided within the main tube between the first and second openings defined by the by-pass tube. A second valve to regulate the passage of gasses within the by-pass tube and means for controlling the first valve are also provided. Upon actuation of the first valve, gases in the vessel assist in the braking of the vehicle by creating a pressure change in the engine. The by-pass tube and second valve provide a means for relieving back pressure against the engine without losing continuity in braking assistance.
