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 11):
A method of operating an internal combustion engine that comprises a combustion chamber having a volume defined by a housing and a reciprocating piston that in use reciprocates relative to said housing between a top dead center position and a bottom dead center position to vary said volume and a catalyst provided on said piston, said method comprising:\n admitting an intake gas comprising an aspirant into said combustion chamber; reducing the volume of said combustion chamber to compress said intake gas by moving said piston relative to said housing towards said top dead center position to raise from a first pressure to a second pressure the pressure in said housing; injecting an aqueous fluid and a steam reforming fuel into said intake gas in said combustion chamber when the pressure in said combustion chamber reaches a predetermined pressure intermediate said first and second pressures and said piston is disposed intermediate said top dead center and bottom dead center positions 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 combustion chamber is at least at said second pressure, admitting a combustible fuel into said combustion chamber and combusting said combustible fuel and hydrogen, wherein combusting said combustible fuel and hydrogen causes movement of said piston relative to said housing towards said bottom dead center position to increase the volume of said combustion chamber and said movement of said body towards said bottom dead center position provides an energy output of said combustion chamber, and wherein said aqueous fluid and steam reforming fuel are injected into said combustion chamber when said volume is partially defined by a wall of said housing that is sealingly engaged by said piston.
