Exhaust heated hydrogen and oxygen producing catalytic converter for combustion engine

Claim 1

In combination with an internal combustion engine of the type having an air induction system including primary fuel inlet means and an exhaust system for combustion gases, supplemental fuel inlet means for said induction system including steam generator means having a steam outlet, a gas generator housing having a predetermined amount of iron filings disposed therein and fluid inlet and outlet means, means connecting said steam outlet with said fluid inlet means, and means communicating said fluid outlet means with said supplemental fuel inlet means, said exhaust system including portions which are heated to a high degree as a result of operation of said engine, said heated portions of said exhaust system being in good transfer relation with said gas generator housing for heating the internal surfaces thereof and said iron filings, the passage of steam through said housing and in intimate contact with the heated iron filings in said housing serving to further elevate the temperature of said steam and to produce hydrogen and oxygen gas for passage through said housing outlet and to said supplemental fuel inlet means, said exhaust system including an elongated exhaust manifold, said generator housing comprising an elongated tubular member through whose opposite end portions said fluid inlet and outlet means open, said tubular member being disposed in good heat transfer relation with the external surfaces of said exhaust manifold, said steam generator including a horizontally elongated housing provided with a pair of inner transverse partitions spaced from the opposite ends of said steam generator housing and dividing the latter into opposite end chambers and a central disposed between said partitions, a plurality of elongated horizontal heat transfer tubes extending through said central chamber and opening into said end chambers at their opposite ends, the opposite ends of said heat transfer tubes being sealed relative to said partitions, exhaust gas inlet means opening into one of said end chambers, exhaust outlet means opening outwardly of the other of said end chambers, means connecting said exhaust system to said exhaust gas inlet means, said central chamber including an upper outlet comprising said steam outlet and an inlet through which water to be heated into steam may be admitted into said central chamber, water supply means operatively associated with said central chamber inlet for supplying water thereto, said water supply means including heating means operative to heat the water supplied thereby, said water supply means including exhaust gas temperature sensing controlled valve means operative to admit additional quantities of heated water into said water and steam compartment means in response to the temperature of the exhaust gas at said outlet end of said exhaust conduit means being elevated to a predetermined level.
