Recombustion catalytic device for use in a spark ignition internal combustion engine employing a vaporizable liquid hydrocarbon fuel
Abstract
Abstract A CATALYTIC DEVICE FOR PRECONDITIONG A CARBURETED MIXTURE OF A VOLATILIZABLE HYDROCARBON LIQUID FUEL AND AIR, THE MIXTURE TO BE FED TO THE INTAKE OF A SPARK IGNITION INTERNAL COMBUSTION ENGINE. THE CATALYZER WHICH IN THE PRIOR ART WAS CARRIED BY COARSE MESH SCREENS OF PLANAR CONFIGURATION IS IN THE INSTANT INVENTION CARRIED BY FINE MESH WIRE CLOTH OF DEEP DISH CONFIGURATION WHICH PROVIDE LONGER SURFACE CONTACT BETWEEN THE MIXTURE AND THE CATALYZER, AND CREATE TORTUOUS FLOW PASSAGES FOR THE CARBURETED MIXTURE THEREBY LENGTHENING THE TIME OF EX POSURED TO THE CATALYTIC SURFACES AND ALSO BY SCRUBBING THE CATALYTIC SURFACES REDUCE THE THICKNESS OF THE CATALYTICIMPENDING GASEOUS STATIC BOUNDARY LAYERS AT SAID SURFACES.
