Abstract
Abstract A water vapor injection system for an internal combustion engine comprising an air washer and moisturizer for supplying clean moisturized air to a carburetor and method therefore. The device and method comprises a container for containing water or other suitable solution and, having directional scoops on the top for directing the flow of air onto the blades of a fan which is mounted on a hollow shaft immersed in the water with a spinner mounted on the same shaft and ports in the shaft arranged just above the spinner. A slotted impinger ring and a filter are arranged in a circumferential groove around the container and a tube is connected between the groove and a carburetor to supply the clean moisturized air to the carburetor to thereby permit the gas air mixture to burn more efficiently and to reduce exhaust pollution.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
In combination, a carburetor and a suction operated water vapor injection system for supplying clean moisturized air to said carburetor comprising a container for containing a liquid solution having vents in the form of directional scoops for venting air therein; filter means; fan operated impeller means arranged in said container to enable the air vented through said directional scoops to impinge thereon, and containing means for pumping said liquid solution and causing it to impinge on said filter, said means for pumping comprising a hollow shaft and a circular spinner disk arranged on said shaft with ports arranged on said shaft just above said circular spinner disk; and output means for connecting said carburetor to said system for rotating said fan operated impeller means and having said filter means arranged adjacent thereto.
Claim 2
Dependent Claim
132 words
In combination, a carburetor and a suction operated water vapor injection system for supplying clean moisturized air to said carburetor comprising a container for containing a liquid solution having vents in the form of directional scoops for venting air therein; filter means; fan operated impeller means arranged in said container to enable the air vented through said directional scoops to impinge thereon, and containing means for pumping said liquid solution and causing it to impinge on said filter, said means for pumping comprising a hollow shaft and a circular spinner disk arranged on said shaft with ports arranged on said shaft just above said circular spinner disk; and output means for connecting said carburetor to said system for rotating said fan operated impeller means and having said filter means arranged adjacent thereto.
Claim 3
Dependent Claim
30 words
The device as described in claim 1 further containing a slotted impinger ring arranged in close proximity to the circumference of said slotted impinger disk for atomizing said liquid solution.
Claim 4
Independent Claim
86 words
A method for supplying cleaN moisturized air to a carburetor of an internal combustion engine system comprising the steps of: venting air into a liquid container having directional scoops onto the blades of a fan operated impeller means operative to pump said liquid contained in said container on to a rotating disk which is rotated by said fan operated impeller means, vaporizing said liquid which is pumped onto said rotating disk passing said vapor through a filter and thence through a suction outlet to said carburetor
Claim 5
Independent Claim
86 words
A method for supplying cleaN moisturized air to a carburetor of an internal combustion engine system comprising the steps of: venting air into a liquid container having directional scoops onto the blades of a fan operated impeller means operative to pump said liquid contained in said container on to a rotating disk which is rotated by said fan operated impeller means, vaporizing said liquid which is pumped onto said rotating disk passing said vapor through a filter and thence through a suction outlet to said carburetor
Claim 6
Dependent Claim
25 words
The method of claim 3 wherein said vaporized liquid is further atomized by an impinging ring arranged adjacent to the circumference of said rotating disk.
Claim 7
Dependent Claim
10 words
The method of claim 4 wherein said liquid is water.
Claim 8
Dependent Claim
16 words
The method of claim 4 wherein said liquid is a mixture of ether and wood alcohol.
Claim 9
Dependent Claim
10 words
The method of claim 4 wherein said liquid is methanol.
