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 1):
A method of operating an internal combustion engine that comprises a housing and a movable body that form a combustion chamber that has a single enclosed volume that is variable by movement of said movable body relative to said housing, and a catalyst contained in said single enclosed volume, said method comprising:\n at a first pressure in said single enclosed volume admitting an intake gas comprising an aspirant into said single enclosed volume; moving said body relative to said housing to reduce the volume of said single enclosed volume to compress said intake gas to raise the pressure in said single enclosed volume to a second pressure that is greater than said first pressure; admitting an aqueous fluid and a steam reforming fuel into said single enclosed volume when the pressure in said single enclosed volume reaches a predetermined pressure intermediate said first and second pressures 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; and when the pressure in said single enclosed volume is at least at said second pressure, admitting a combustible fuel into said single enclosed volume and combusting said combustible fuel and hydrogen, wherein combusting said combustible fuel and hydrogen causes movement of said movable body relative to said housing to increase the volume of said single enclosed volume and said movement of said movable body provides an energy output of said combustion chamber.
