Abstract
Abstract An internal combustion engine is provided with a carburetor operatively connected with a water injector means. An automatic transmission is operatively connected to the engine, and transmission fluid from the automatic transmission passes through a heat exchanger in a watertight container of the water injector means to cool the transmission fluid and to heat the water in the container to produce water vapor which is then mixed with the gasoline in the venturi tube of the carburetor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
In combination, an internal combustion engine, a carburetor operatively connected with said engine, an automatic transmission operatively connected to said engine and having transmission fluid therein, water vapor injector means connected to said carburetor to provide water vapor thereto, said water vapor injector means including a container receiving water therein, and heat exchange means in said container, said heat exchange means being operatively connected with said automatic transmission for receiving fluid from said transmission to cool the transmission fluid and to heat the water in said container to produce water vapor.
Claim 2
Dependent Claim
91 words
In combination, an internal combustion engine, a carburetor operatively connected with said engine, an automatic transmission operatively connected to said engine and having transmission fluid therein, water vapor injector means connected to said carburetor to provide water vapor thereto, said water vapor injector means including a container receiving water therein, and heat exchange means in said container, said heat exchange means being operatively connected with said automatic transmission for receiving fluid from said transmission to cool the transmission fluid and to heat the water in said container to produce water vapor.
Claim 3
Dependent Claim
24 words
Apparatus as defined in claim 1 including a combination water-filling means and air intake means operatively connected with a lower portion of said container.
Claim 4
Dependent Claim
29 words
Apparatus as defined in claim 2 wherein said combination water-filling means and air intake means includes an air-metering orifice for controlling the amount of air passing into said container.
Claim 5
Dependent Claim
48 words
Apparatus as defined in claim 1 including control means for controlling the flow of water vapor from said container to said carburetor so as to reduce flow of water vapor at idling speeds of said engine and to increase flow of water vapor as the engine speed increases.
Claim 6
Dependent Claim
49 words
Apparatus as defined in claim 4 wherein said control means comprises a valve, resilient means normally biasing said valve to an open position, and a valve seat against which the valve closes under the influence of vacuum produced by said engine and against the force of said resilient means.
Claim 7
Dependent Claim
72 words
Water-vapor-generating apparatus including a container having upper and lower closed ends, a heat transfer conduit mounted within said container and operatively projecting through one of the ends of said container, valve means in the upper portion of said container responsive to pressure change for controlling the flow of vapor from said container, and means connected to the lower portion of said container for controlling the flow of atmospheric air into said container.
Claim 8
Dependent Claim
72 words
Water-vapor-generating apparatus including a container having upper and lower closed ends, a heat transfer conduit mounted within said container and operatively projecting through one of the ends of said container, valve means in the upper portion of said container responsive to pressure change for controlling the flow of vapor from said container, and means connected to the lower portion of said container for controlling the flow of atmospheric air into said container.
Claim 9
Dependent Claim
101 words
The apparatus of claim 6 in which said conduit is U-shaped and the ends thereof are operatively secured to the upper end of said container, said valve means includes a valve seat and a valve movable selectively into and out of engagement with said valve seat, said valve seat defining an opening which is closed by said valve when the latter is seated and opened when unseated, said last-mentioned means including an upright tube connected at its lower end to said container, and a closure for the upper end of said tube, said closure having at least one air-metering orifice therein.
Claim 10
Dependent Claim
80 words
The apparatus of claim 7 in which said valve means further includes a body having a passage therein which communicates with the interior of said container, said valve and valve seat being mounted inside said passage, a valve support secured to said body and being positioned adjacent to said valve seat, said valve being movably mounted on said valve support, and a spring carried by said valve support engageable with said valve to yieldably urge the latter to open position.
Claim 11
Dependent Claim
49 words
The apparatus of claim 7 in which said closure includes an adjustable valve for controlling the volume of air flowing into said container, said adjustable valve including a cover having a plurality of different-sized orifices therein and a movable plate provided with an aperture selectively registrable with said orifices.
Claim 12
Dependent Claim
69 words
The apparatus of claim 7 in which a plurality of heat-transfer baffles are located within said container in vertically spaced relation, said baffles being disclike and arranged in parallelism with said conduit paSsing therethrough and being engaged therewith in heat-exchanging relation, said baffles being perforated at locations such that the perforations of adjacent baffles are misaligned to provide a tortuous path for the flow of air through said container.
