Internal combustion engine of hydrogen gas

In a hydrogen gas fueled internal combustion engine, the improvement comprising:

• a hydrogen gas jet nozzle provided in a combustion chamber of the engine to directly jet hydrogen gas as fuel into the combustion chamber;
• a source of water at ambient or room temperature;
• and
• a water spray jet nozzle coupled to said water source, said water spray jet nozzle being provided in said combustion chamber, separately and independently of said hydrogen gas jet nozzle, to directly jet a spray of said ambient or room temperature water into said combustion chamber substantially simultaneously with the jetting in of the hydrogen gas;
• the air in said combustion chamber being compressed so that the water sprayed into said combustion chamber is instantly vaporized to steam by igniting of the hydrogen gas jetted into said combustion chamber, thereby utilizing the combustion/explosion energy of the hydrogen gas and the steam energy generated from the vaporization of the steam in combination to obtain mechanical dynamic energy.
