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 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, an oxygen injector to the combustion chamber and a water injector to the combustion chamber. The fuel, oxygen and water injectors controlled by a CPU provide repeated serial pulses of fuel, oxygen and water to complete a charge. An ignition chamber receives a compressed charge then ignited by a spark plug to pass through a restricted port to the main combustion chamber. A source of pressurized concentrated oxygen to the oxygen injector is in a closed air separator having a ceramic membrane of yttrium stabilized zirconia with a synthesized double perovskite nanofiber catalyst coating.
