The fuel vaporizer of the present invention is provided for the purpose of improving the efficiency and decreasing the pollution of internal combustion engines, more particularly those used in automobiles and employing gasoline as a fuel. The fuel vaporizer includes a housing forming three separate chambers. A coiled tube extends within the central chamber and its inlet end portion extends through the first chamber and is connected to the outlet of the gasoline pump. The outlet of the coil communicates with the third chamber, which in turn is connected by a tubing to the carburator of the engine. The central chamber is connected in series with the engine cooling circuit by means of two end tubes extending through the first and last chamber, respectively, and opening within said central chamber. Air is bled from the air intake of the carburator; is passed through the first chamber; and is circulated back to the intake manifold downstream of the carburator. The first and last chambers are filled with granular material and the two end tubes are provided with heat-exchanger plates. The bled air is heated in the first chamber. The gasoline is progressively heated and vaporized to a dry vapor while flowing through the coil and through the heated granulated material in the last chamber before it is fed to the carburator.
In combination, a fluid vaporizer device and an internal combustion engine having an engine coolant circuit, a fuel pump, a carburator, an air intake for said carburator located upstream of the latter, and an intake manifold located downstream from said carburator, said device comprising first, second and third separate chambers, means for circulating heated engine coolant through said three chambers, means for bleeding a portion of the air from said air intake, for circulating said air portion through said first chamber while in heat-exchange relationship with the heated engine coolant circulating through said first chamber and for delivering the heated air to said intake manifold, means for circulating fuel through said second chamber and subsequently delivering said fuel into said third chamber while in heat-exchange relationship with the heated engine coolant circulating through said second and third chambers, granular material filling said second and third chambers, the fuel circulating through said second and third chambers being progressively heated and vaporized so that the fuel attains a gaseous state while in said third chamber, the heated granular material in said third chamber completing conversion of said fuel from liquid to gaseous state, and means for delivering said gaseous fuel from said third chamber to said carburator.
In combination, a fuel vaporizer device and an internal combustion engine having a liquid coolant circuit, a fuel pump, a carburator, an air intake for said carburator located upstream of the same, and an intake manifold downstream from said carburator, said device comprising a housing defining a first, second and third separate chambers in end-to-end relationship, a fuel circulating tube forming a straight fuel inlet section extending completely through said first chamber, and forming a coil located within said second chamber, the outlet end of said coil being in direct communication with said third chamber, a fuel outlet nipple communicating with one side of said third chamber, said fuel inlet section connected to the outlet of said fuel pump and said fuel outlet nipple connected to the fuel inlet of said carburator, a heating liquid inlet pipe extending centrally through said first chamber and communicating with one end of said second chamber, and a heating liquid outlet pipe communicating with the opposite end of said second chamber and extending through said third chamber, heat-conducting strips secured to and surrounding said inlet and outlet pipes, and respectively extending within said first and third chambers, granular material filling said first and third chambers, said inlet and outlet pipes series connected in the liquid coolant circuit of said engine, and an air line series connecting said first chamber with the air intake of said carburator and with the intake manifold of said engine for bleeding part of the air entering the carburator, heating it when flowing through said first chamber and delivering it directly into said intake manifold downstream from said carburator, the fuel circulating through said coil being progressively heated and attaining a completely-gaseous state while in said third chamber.
