This engine inducts Hydrogen and an inert Quench gas into its combustion chamber, compresses the mixture, and injects Hydrogen Peroxide thru catalytic injectors to burn the Hydrogen in the dissociated oxygen that is liberated. Exhaust flows into a Gas Drier/Condenser (GD/C), which removes exhaust steam. Non-condensable gasses are returned to the engine intake in a closed loop where hydrogen is continuously added via a constant pressure regulator to replace burned Hydrogen. Presence of the Quench gas in the mixture effectively reduces total hydrogen available for combustion. This engine could not work as a closed cycle without the GD/C, which contains a pressurized water trap that allows free flow of recycled non-condensable gasses thru that trap, but condenses steam as it passes thru one ceramic plate and comes into direct contact with pressurized water trapped between the ceramic plates. The pressurized water trap separates the GD/C's inlet from its outlet.
