  • Apparatus for reforming combustible into gaseous fuel by reaction with decomposition product of hydrogen peroxide
    Patent number: 4059415
    Abstract: Apparatus for converting a combustible material such as a hydrocarbon or carbon fuel into a gaseous fuel containing H.sub.2 and/or CO by reaction with a heated mixture of O.sub.2 and H.sub.2 O prepared by decomposition of H.sub.2 O.sub.2, characterized by the provision of a venturi section located upstream of the entrance to a reaction chamber for increasing the velocity of the flow of the O.sub.2 --H.sub.2 O mixture and arrangement of the combustible feed line to add the combustible to the mixture at the venturi.
    Type: Grant
    Filed: May 27, 1976

  • Method of accelerating evaporation of fuel in internal combustion engine intake system by heat evolved by decomposition of H.sub.2 O.sub.2 and apparatus for same
    Patent number: 4056086
    Abstract: H.sub.2 O.sub.2 or its aqueous solution is catalytically decomposed into oxygen and water in a vessel having radiation fins formed on its wall, and the heat of decomposition is transferred to air drawn into the induction passage, to fuel ready to jet into the drawn air or to an air-fuel mixture flowing through the induction passage. The evolved oxygen is fed to the combustion chamber and/or the exhaust line of the engine.
