Device for enhancing the vaporization of a fuel component of a flowing fuel-air mixture

Claim 1

FOR AN INTERNAL COMBUSTION ENGINE PROVIDED WITH AN INTAKE MANIFOLD AND A CARBURETER HAVING AN EFFLUX ORIFICE THROUGH WHICH A FUEL-AIR MIXTURE IS SUPPLIED TO THE INFLUX ORIFICE OF THE MANIFOLD, A FUEL VAPORIZER ADAPTED TO BE INTERPOSED BETWEEN SAID ORIFICES COMPRISING A FIRST AND A SECOND CONCAVE SHELL COAXIALLY JOINTED TOGETHER IN A PLANE AT THEIR PERIMETERS TO FORM AN ENCLOSURE, A DISC-LIKE BAFFLE DIVIDING THE ENCLOSURE INTO AN UPPER AND A LOWER CHAMBER WHEREBY SAID BAFFLE FORMS THE BOTTOM WALL FOR THE UPPER CHAMBER AND A PORTION OF ONE OF SAID SHELLS FORMS THE BOTTOM WALL FOR THE LOWER CHAMBER, A PLURALITY OF PORTS IN THE BAFFLE PERMITTING INTERCOMMUNICATION BETWEEN THE CHAMBERS, AN ORIFICE IN THE FIRST SHELL ALIGNED WITH THE EFFLUX ORIFICE, AN ORIFICE IN THE SECOND SHELL ALIGNED WITH THE INFLUX ORIFICE, A FILAMENTOUS VAPORIZING PACKET ARRANGED IN AT LEAST ONE OF THE CHAMBERS SO THAT THE LENGTH OF THE FILAMENTS THEREOF IS SUBSTANTIALLY PARALLEL TO RADIAL FLOW BETWEEN THE ORIFICE OF THE CHAMBER AND SAID BAFFLE PORTS, SAID PACKET HAVING A SUBSTANTIALLY OBLONG CROSS-SECTION GENERALLY PARALLEL TO SAID FILAMNETS AND TERMINATING IN INNER AND OUTER SUBSTANTIALLY CIRCULAR ENDS OF DIFFERENT RADII AND ARRANGED WITH RESPECT TO THE CHAMBER ORIFICE AND SAID BAFFLE PORTS, SAID FILAMENTS BEING IN CLOSELY ASSOCIATED ARRANGEMENT AND HAVING FLOW PASSAGES THEREBETWEEN FOR MOVEMENT OF FUELAIR MIXTURE BETWEEN SAID CHAMBER ORIFICE AND SAID BAFFLE PORTS, AND A BAFFLE ARRANGED SUBSTANTIALLY COAXIALLY WITH ONE OF SAID CIRCULAR ENDS OF THE PACKET AND EXTENDING UPWARDLY FROM THE BOTTOM WALL OF THE CHAMBER CONTAINING THE PACKET FOR COMPELLING THE MIXTURE TO ENTER THE PACKET AT A LEVEL ABOVE THE SAID BOTTOM WALL.

Claim 3

A DEVICE FOR ENHANCING THE VAPORIZATION OF THE FUEL COMPONENT OF A FLOWING FUEL-AIR MIXTURE, COMPRISING MEANS FORMING A FLOW CHAMBER HAVING AN ENTRY AND AN EXIT FOR THE PASSAGE OF FLUID THERETHROUGH IN DIRECTION FROM THE ENTRY TO SAID EXIT AND HAVING SUBSTANTIALLY IMPERVIOUS WALLS EXTENDING FROM THE FORMER TO THE LATTER FOR GUIDING FLOW IN SAID DIRECTION AND A VAPORIZING PACKET FOR FLOW OF MIXTURE FROM AN ENTRY END PORTION THEREOF, TO AN EXIT END PORTION THEREOF, SAID PACKET BEING POSITIONED IN SAID FLOW CHAMBER WITH ITS ENTRY END PORTION EXPOSED AT SAID FLOW CHAMBER ENTRY AND ITS EXIT AND PORTION EXPOSED AT SAID FLOW CHAMBER EXIT AND HAVING A PLURALITY OF CLOSELY ASSOCIATED SMOOTH RIBBON FILAMENTS THAT EXTEND INDIVIDUALLY FROM SAID ENTRY END PORTION TO SAID EXIT END PORTION WITH INTERVENING LENGTHWISE EXTENDING SPACES SO THAT SAID RIBBON FILAMENTS ARE INTERSPERSED WITH AIR PASSAGES EXTENDING LENGTHWISE GENERALLY IN THE DIRECTION OF FLOW OF THE FUEL-AIR MIXTURE FROM SAID ENTRY END PORTION TOWARD SAID EXIT END PORTION THEREOF, SAID PACKET HAVING A CROSS-SECTION, TRANSVERSELY OF SAID LENGTHWISE EXTENDING FILAMENTS AND OF THE SAID LENGTHWISE EXTENDING INTERMINGLED AIR PASSAGES, THAT IS SUBSTANTIALLY THE SAME AS THE CROSS SECTION OF SAID FLOW CHAMBER MEANS BETWEEN SAID IMPERVIOUS WALLS THEREOF, SAID RIBBON FILAMENTS HAVING PORTIONS THEREOF DISTORTED OUT OF THEIR LONGITUDINAL AXES TO COACT IN LATERALLY SPACING ADJACENT RIBBON FILAMENTS FROM ONE ANOTHER AND THEREBY COACT IN PROVIDING SAID AIR PASSAGES AND IN MAINTAINING SAID CROSS-SECTION OF SAID PACKET SO THAT IT CONFORMS SUBSTANTIALLY TO THE SAID CROSS-SECTION OF SAID FLOW CHAMBER MEANS WHEREBY FUEL-AIR MIXTURE ENTERING THE ENTRY OF THE LATTER IS CONSTRAINED TO FLOW ALONG SAID AIR PASSAGE AND FUEL DROPLETS DEPOSITED ON SAID RIBBON FILAMENTS ARE BY THE MIXTURE FLOWING ALONG SAID AIR PASSAGES FILMED OUT UPON AND ATTENUATED LENGTHWISE OF SAID RIBBON FILAMENTS IN THE DIRECTION TOWARD SAID EXIT, THEREBY TO ENHANCE VAPORIZATION THEREOF.

Claim 4

A DEVICE FOR ENHANCING THE VAPORIZATION OF THE FUEL COMPONENT OF A FLOWING FUEL-AIR MIXTURE, COMPRISING MEANS FORMING A FLOW CHAMBER HAVING AN ENTRY AND AN EXIT FOR THE PASSAGE OF FLUID THERETHROUGH IN DIRECTION FROM THE ENTRY TO SAID EXIT AND HAVING SUBSTANTIALLY IMPERVIOUS WALLS EXTENDING FROM THE FORMER TO THE LATTER FOR GUIDING FLOW IN SAID DIRECTION AND A VAPORIZING PACKET FOR FLOW OF MIXTURE FROM AN ENTRY END PORTION THEREOF, TO AN EXIT END PORTION THEREOF, SAID PACKET BEING POSITIONED IN SAID FLOW CHAMBER WITH ITS ENTRY END PORTION EXPOSED AT SAID FLOW CHAMBER ENTRY AND ITS EXIT AND PORTION EXPOSED AT SAID FLOW CHAMBER EXIT AND HAVING A PLURALITY OF CLOSELY ASSOCIATED SMOOTH RIBBON FILAMENTS THAT EXTEND INDIVIDUALLY FROM SAID ENTRY END PORTION TO SAID EXIT END PORTION WITH INTERVENING LENGTHWISE EXTENDING SPACES SO THAT SAID RIBBON FILAMENTS ARE INTERSPERSED WITH AIR PASSAGES EXTENDING LENGTHWISE GENERALLY IN THE DIRECTION OF FLOW OF THE FUEL-AIR MIXTURE FROM SAID ENTRY END PORTION TOWARD SAID EXIT END PORTION THEREOF, SAID PACKET HAVING A CROSS-SECTION, TRANSVERSELY OF SAID LENGTHWISE EXTENDING FILAMENTS AND OF THE SAID LENGTHWISE EXTENDING INTERMINGLED AIR PASSAGES, THAT IS SUBSTANTIALLY THE SAME AS THE CROSS SECTION OF SAID FLOW CHAMBER MEANS BETWEEN SAID IMPERVIOUS WALLS THEREOF, SAID RIBBON FILAMENTS HAVING PORTIONS THEREOF DISTORTED OUT OF THEIR LONGITUDINAL AXES TO COACT IN LATERALLY SPACING ADJACENT RIBBON FILAMENTS FROM ONE ANOTHER AND THEREBY COACT IN PROVIDING SAID AIR PASSAGES AND IN MAINTAINING SAID CROSS-SECTION OF SAID PACKET SO THAT IT CONFORMS SUBSTANTIALLY TO THE SAID CROSS-SECTION OF SAID FLOW CHAMBER MEANS WHEREBY FUEL-AIR MIXTURE ENTERING THE ENTRY OF THE LATTER IS CONSTRAINED TO FLOW ALONG SAID AIR PASSAGE AND FUEL DROPLETS DEPOSITED ON SAID RIBBON FILAMENTS ARE BY THE MIXTURE FLOWING ALONG SAID AIR PASSAGES FILMED OUT UPON AND ATTENUATED LENGTHWISE OF SAID RIBBON FILAMENTS IN THE DIRECTION TOWARD SAID EXIT, THEREBY TO ENHANCE VAPORIZATION THEREOF.
