Abstract:
1. In an internal combustion engine having at least one cylinder forming a combustion chamber and within such cylinder is a reciprocable piston movable relative to said cylinder through a compression stroke followed by a power stroke, the improvement comprising means for introducing a quantity of a combustible fuel mixture to said combustion chamber for compression in response to movement of said piston during said compression stroke; means for igniting said fuel during compression of said mixture and thereby generating in said combustion chamber heat and an expansion force operable to move said piston through said power stroke following said compression stroke; and means for introducing into said combustion chamber at a selected time interval following ignition of said fuel a quantity of water, the time of said injection of water being such that heat from the combustion of said fuel is sufficient to convert the injected water to superheated steam, the conversion of said water into steam generating in said combustion chamber an additional force operable to assist said expansion force in moving said piston through said power stroke.
