  • Patent number: 8959901
    Abstract: A metal-gas battery that utilizes an exhaust gas stream from a combustion engine as reactive gases is provided. Almost constant concentration of exhaust gases are supplied to the metal-gas battery via an existing engine systematic combustion system. The systematic combustion system keeps a definite air fuel mixture (A/F) that acts to enhance the fuel efficiency of the vehicle, and the metal-gas battery leverages the existing vehicle air management system. Exhaust heat of the exhaust gases is sometimes utilized for the heat control of the vehicle, and then the cooled exhaust gases are introduced into the metal-air battery to be consumed during a cathode reduction reaction to create and store electrical energy. The metal-gas battery supports the cleaning of exhausted gases using existing emission catalysts.

  • Publication number: 20150040546
    Abstract: An internal combustion engine includes a chamber and inlet valving operable to admit constituents of a combustible mixture into the chamber for combustion therein to provide a pressure increase in the chamber. First input valving admits a liquid into the chamber and a control system controls the first input valving such that the liquid is admitted to the chamber to compress at least one constituent of the combustible mixture. Outlet valving releases an outflow of the liquid from the chamber under an influence of the pressure increase as an energy output of the chamber. Second input valving selectively admits a heated aqueous fluid into a region of the chamber in which combustion of the combustible mixture occurs to promote a hydrogen separation process in the chamber to provide hydrogen that is combusted in the chamber. A supply system supplies the heated aqueous fluid to the second input valving.
