Abstract

Abstract A vapor injection system for an internal combustion engine including a mist chamber having a perforated section communicating with the inlet to the carburetor and a water tube and an air tube discharging jets of water and air, respectively, in convergent paths within the mist chamber to create an atomized water spray. The perforated section of the mist chamber assures the complete atomization of all water particles passing into the carburetor.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 299 words
A vapor injection system in combination with an internal combustion engine having a carburetor and an air inlet to the carburetor having a flow axis toward the carburetor, comprising: a. a mist chamber having an enclosure wall, b. at least a portion of said wall comprising a perforated section having a plurality of apertures small enough to permit the passage only of water mist particles of a predetermined size, c. means mounting said perforated section in fluid communication with the air inlet to said carburetor, d. a water tube having a first discharge end projecting through said enclosure wall so that said first discharge end is within said mist chamber, e. an air tube having a second discharge end projecting through said enclosure wall so that said second discharge end is within said mist chamber, f. said second discharge end being proximate to said first discharge end and positioned to force a stream of air to intercept at an acute angle a stream of water discharged from said first discharge end in the same general direction as said air stream, g. means for supplying water under pressure through said water tube, h. means for supplying compressed air through said air tube with sufficient pressure to atomize the intercepted stream of water from said first discharge end and to force said atomized water particles in a path at a substantial angle to the flow axis of said carburetor air inlet, i. a baffle member, j. means mounting said baffle member within said mist chamber opposing said first discharge end at an angle to, and in, the path of said atomized water particles to further atomize said water particles and to deflect said water particles at an angle to said path, through said perforated section and into said carburetor air inlet.
Claim 2
Dependent Claim 299 words
A vapor injection system in combination with an internal combustion engine having a carburetor and an air inlet to the carburetor having a flow axis toward the carburetor, comprising: a. a mist chamber having an enclosure wall, b. at least a portion of said wall comprising a perforated section having a plurality of apertures small enough to permit the passage only of water mist particles of a predetermined size, c. means mounting said perforated section in fluid communication with the air inlet to said carburetor, d. a water tube having a first discharge end projecting through said enclosure wall so that said first discharge end is within said mist chamber, e. an air tube having a second discharge end projecting through said enclosure wall so that said second discharge end is within said mist chamber, f. said second discharge end being proximate to said first discharge end and positioned to force a stream of air to intercept at an acute angle a stream of water discharged from said first discharge end in the same general direction as said air stream, g. means for supplying water under pressure through said water tube, h. means for supplying compressed air through said air tube with sufficient pressure to atomize the intercepted stream of water from said first discharge end and to force said atomized water particles in a path at a substantial angle to the flow axis of said carburetor air inlet, i. a baffle member, j. means mounting said baffle member within said mist chamber opposing said first discharge end at an angle to, and in, the path of said atomized water particles to further atomize said water particles and to deflect said water particles at an angle to said path, through said perforated section and into said carburetor air inlet.
Claim 3
Dependent Claim 21 words
The invention according to claim 1 in which the surface of said baffle member opposing said first discharge end is rough.
Claim 4
Dependent Claim 24 words
The invention according to claim 1 in which the portion of the enclosure wall of said mist chamber opposite said perforated section is solid.
Claim 5
Dependent Claim 33 words
The invention according to claim 3 in which said solid enclosure wall portion is concave toward said carburetor air inlet for deflecting additional water particles through said perforated section into said air inlet.
Claim 6
Dependent Claim 47 words
The invention according to claim 1 in which said mist chamber is mounted above said air inlet, said perforated section forming the bottom of said mist chamber, and said barrier member is mounted above said perforated section for deflecting atomized water particles down through said perforated section.
