Abstract:
An internal combustion engine includes a combustion chamber. The chamber includes a body that is movable in the chamber to vary the chamber volume and contains a catalyst. First valving is operable to admit an intake gas into the chamber and second valving connected with an aqueous fluid supply system is operable to admit an aqueous fluid and a steam reforming fuel into the chamber. A controller is configured to cause the second valving to admit a aqueous fluid and an amount of the steam reforming fuel into the chamber and when a predetermined condition exists in the chamber during compression of the intake gas to absorb heat generated by the compression of the intake gas in the presence of the catalyst to promote a steam reformation process to separate hydrogen from the steam reforming fuel or the aqueous fluid.

Claim (Index 18):
An internal combustion engine comprising:\n a housing and a body movable in said housing, said body and housing defining a combustion chamber that has a single enclosed volume that is variable by movement of said body relative to said housing; a catalyst in said single enclosed volume; first valving to admit an intake gas into said single enclosed volume; an aqueous fluid supply system; second valving connected with said aqueous fluid supply system and operable to admit aqueous fluid from said aqueous fluid supply system and a steam reforming fuel into said single enclosed volume; and a controller configured to i) cause said first valving to admit a charge of intake gas into said single enclosed volume and ii) when a predetermined condition exists in said single enclosed volume during movement of said body to reduce the volume of said single enclosed volume so as to compress said intake gas to raise from a first pressure to a second pressure the pressure of said intake gas, cause said second valving to admit aqueous fluid from said aqueous fluid supply system and an amount of said steam reforming fuel into said single enclosed volume so that said aqueous fluid and steam reforming fuel absorb heat generated by said compression of said intake gas and said catalyst promotes a steam reformation process by which hydrogen is separated from said steam reforming fuel or said aqueous fluid, wherein said combustion of said fuel and hydrogen causes movement of said body to increase the volume of said single enclosed volume and said movement of said body provides an energy output of said combustion chamber.
