An internal combustion engine designed to operate with hydrogen fuel, comprises means for mixing water in the form of droplets, spray, or mist with gaseous hydrogen. The water-containing hydrogen gas is then introduced along with air in proportion for practical internal combustion and efficient power output to the cylinders or combustion chambers of the engine for combustion. In one embodiment of the invention, water vapor is condensed from the exhaust gases from the engine, and the condensed water is used as the source of water to be mixed with hydrogen fuel so as to provide a continuing, self-supporting system. The resulting exhaust emissions from the engine are very low in oxides of nitrogen, and, in addition, engine backfiring is eliminated while the efficiency and power output of the engine is improved.

An internal combustion engine comprising one or more combustion chambers; an engine fuel intake for delivering a fuel mixture of gaseous hydrogen and air to said chambers for sequential combustion therein; fuel feed means for providing a gaseous fuel mixture of hydrogen and air in metered relation to the engine fuel intake; a hydrogen supply line for introducing gaseous hydrogen to said fuel feed means; water distributing means for producing water droplets, spray, or mist from supplied liquid water and for introducing said water droplets, spray, or mist to said hydrogen supply line to mix with the gaseous hydrogen therein prior to the introduction of said gaseous hydrogen to said fuel feed means; condensor means for condensing water vapor from the combustion gases resulting from the combustion of hydrogen in said chambers; and means for supplying the condensed water to said water distributing means in such proportion to provide sufficient water in the fuel mixture to inhibit backfiring during operation of the engine as well as to reduce the oxides of nitrogen in the exhaust gases from the engine. A method of inhibiting backfiring and generation of oxides of nitrogen in a hydrogen-fueled internal combustion engine comprising: (a) storing water; (b) producing liquid water droplets, spray, or mist from the stored water; (c) mixing the droplets, spray, or mist with gaseous hydrogen; and (d) introducing air and the gaseous mixture of hydrogen and water droplets, spray, or mist in metering relation to the engine intake for combustion in the cylinders, wherein the water droplets, spray, or mist is admixed with the hydrogen in a predetermined mass ratio sufficient to inhibit backfiring and the generation of oxides of nitrogen during the operation of said engine.
