Abstract
Abstract An open cycle internal combustion engine, uses in combination oxygen and hydrogen burned as fuel in the combustion chamber after being mixed with a surplus gas, and has a substantially closed system which recirculates the surplus gas through the system for reuse and expels only the water of combustion to the atmosphere. Heat exchangers and a trap separates the water of combustion from the surplus gas by liquifing the water vapor contained in the engine''s exhaust. Hot engine exhaust is initally cooled by heat exchange contact with the separated water and said separated water is simultaneously warmed to vapor by the exchange of heat before expelling the vapor to the atmosphere. The surplus gas is then reused with fresh supplies of hydrogen and oxygen. Throttle valves are adjusted to vary the quantity of oxygen and hydrogen for speed control and at the same time maintain a proper proportioning of the gases at whatever quantity may be established for a selected speed.

Claim 1
Independent Claim
329 words
In an open cycle internal combustion engine, which has one or more combustion chambers in which the pressure and volume varies in a cyclic manner to produce work, an intake to admit a combustible charge, a means to ignite the combustible charge, an exhaust to remove the combusted charge, a means to seal the combustion chamber from the crankcase, and a means to cyclically seal the combustion chamber''s intake and exhaust, a fuel system comprising a mixing passage and conduit means from said mixing passage to said intake, a first source of gas comprising oxygen as a fuel, a supply line and a throttle valve therein, from said first source to the mixing passage, a second source of gas comprising hydrogen as a fuel, a supply line and a throttle valve therein, from said second source to the mixing passage, the ratio of gases of the types supplied from said first and second sources is at the stoichiometric ratio of said gases, a surplus gas filling the various passageways of the system which when combined with the gases from said first and second sources in said mixing passage forms said combustible charge, a passageway for said surplus gas and water of combustion from said exhaust to a water separating device in said passageway, said water seperating device is comprised of a condenser and a trap, adapted to liquify said water of combustion, and to separate said surplus gas from said water of combustion, a surplus gas return line for said surplus gas leading from said water separating device to said mixing passage to maintain said surplus gas in the system, a liquid water line from said water separating device to a heat exchanger, said heat exchanger being in heat exchange relationship between said liquid water line and said passageway and being designed to raise the temperature of said liquid water to a point below boiling, and a liquid water discharge line from said heat exchanger open to the atmosphere.
