GASOLINE CONSERVING POWER INCREASING vAPo nznn John Carl Wichmann and Nu on wicnmann,
Los Angeles, Calif.
Application June 2, 1947,Serial' No."751,770
Our invention relates to a supercharging gasoline conserving'power increasing vaporizer,
particularly designed for use in connection withinternal combustion engines and one of the principal objects of our invention, is to generally improve upon and simplify the gaseous fuel supply systems shown in our copending application for U. S. Letters Patent filed July 29, 1944, Ser. No. 547,259, also application filed May 20, 1946, Ser. No. 671,042. r
A further object of our invention is, to provide a simple, highly effective and easily adjusted and controlled system for delivering to the carbureted air passing from 'the carburetor to the intake manifold, a heated vaporized mixture of properly proportioned oil, oil vapor, air and water, in order to materially increase the power output of the .engine with which the equipped carburetor is'associated, alsoconserving gasoline consumption, minimizing the development of carbon in the valve and piston chambers, eli -4- inating tendency of the motor to ping or knock while in service, providing for easy starting and quick acceleration, also, cooler and smoother running of the motor and achieving economy in fuel costs, due to the ability to operate the motor effectively with the lower grades of gasoline.
With the foregoing and other objects in view, Our invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:
Fig. 1 is a diagrammatic elevational view with parts in section of our improved system and showing same associated with an internal combustion engine and its carburetor.
Fig. 2 is an enlarged vertical section taken on the line 2-2 of Fig. 1.
Figs. 3 and 4 are detail sectional views of certain check valves used in our improved system.
Referring by numerals to the accompanying drawings, which illustrate a preferred embodiment of the invention, l0, designates the engine cylinder block, H, a portion of the crank case, l2, an air filter, l3, the carburetor and I4, an adapter ring located between the carburetor and intake manifold I5. A pump I6 forces gasoline through a duct I1, having portions located adjacent block H], to and through a strainer l8 and duct l9, to carburetor 3.
Leading from the water chamber of block ID, to a strainer 2| is a duct 22, and leading from the latter to a housing 23, having an inwardly opening check valve 24, is a duct 25. A screw 2 Claims. (01. 123-25) plugrvalve 26 controlspthe, fiow'of water into.

Leading from thechamber within crank hous ing below the normal oil level therein; to a strainer 21, equipped with a'screw plug valve28,
is a duct, 29and leading from strainer 21, to housing 23 above the-valve 34 therein, isa duct 3fl.
Leading from; valve housing 23 to aduct 3|, is a'duct32 having a flow control valve 33 and said duct "3|; equipped with'a flow control-valve '34, leads to adapter ring l4. 1
Leading from the upper: portion of the air chamberin crank case. |'|,above the oilzlevel. therein, to a housing-35yhaving an inwardly opening checkvalve 36, is a duct ST-andlocated in a vertical-portionethereof, adjacent the crank case'is an oil trap 3B. g 1
.Leading from housing 35, above the valve therein, is aductdq which is connected by means of athree way coupling, to ducts 3| and 32. A coupling 40 connects duct 39 to a valve housing 4|, having an inwardly opening check valve 42 and connected to said valve housing in front of the valve therein, is an open ended air inlet fitting 43.
A fitting which serves as a crank case ventilator and oil funnel, comprises an upright housing 44, carried by an axial tube 45, the open lower end of the latter entering the top of the chamber in the crank case and the upper end of said tube being flared outwardly against the wall of said housing. Surrounding tube in the lower portion of the housing is a partition 46 provided with a plurality of apertures 4! and formed through the wall of housing 44 below said partition, is an air inlet aperture 48.
The chamber between housing 44 and tube 45 above partition 46 is filled with air filtering material 49, preferably fibrous, and formed through the upper portion of the wall of said tube are apertures 50 (see Fig. 2).
During engine operation, pump l6 forces liquid gasoline through duct H to and through gasoline strainer 8 and |9 to carburetor |3 wherein the air from air filter I2 is carbureted and passes through adapter ring |4 into and through adapter ring I 4 into and through the intake manifold leading to the engine cylinders. Considerable suction produced in the intake manifold will, as the various check valves in the system are opened, prevails in ducts 22, 25, 30, 32, 39, 43 and 3| and the various fittings associated therewith and thus air will be drawn through fitting 43, past check valve 42 in housing 4|, and then through ducts 39 and 3|.
Simultaneously, oil vapor and air will be drawn from the crank case through duct 3'! past check valve 36 in housing 35 and then through duct 39 to duct 3!.
Any liquid oil drawn into duct 31 will, in passing through trap 38 separate from the vapor and drop back into the crank case and at the same time, moisture, either; cool or hptgwater, wilhbe drawn from the water chamber of the-motor block l through duct 22, strainer 2|, duct 25,
duct 30, past check valve 24 and thence through the crank case ll through duct 29, strainer 2fl,
duct 30, past check valve 24, and thence through valve 33 and duct 32 to duct 3|.
Thus air, oil, oil vapor andimoisture, eithercool or hot water are simultaneously drawn into duct 3|, and after mixing through the moisturepasses into the intake manifold of the engine to mi-x -Withandmaterially reinforce the carbureted air flowing from the carburetor to saidintake manifold andthe-- combustion chambers of the engine.
Obviously, this I intimate mixture of carbureted air, moisture,"atmosphericair, oil, vapor; oil mixture; greatly enhances the-development of power as said-mixture is ignited and burns in the combustionchambers of-the-engine and at thesame time, perfect lubrication for the-valves, valve stems, piston heads and cylinder wallsisassured.
Bytaking moisture from the water circulation chamber of the engine block andwithdrawing oi-l and-oil vapor from-thecrank-case, the'necessity for separate Waterand oil containers and the periodic servicing thereof'is eliminated.
To insure best results, the valves 26 'and 28 are barely cracked or opened to only a slight degree,, and valve-34is regulated-to control the volume flow of the mixture tothe intake manifold.
Thus it will be seen that we have provided a gasoline conserving power increasing vaporizer for internal combustion engines, which is simple in structure, inexpensive of manufacture and very effective in performing the functions for which it is intended.
Minor changes in the size, form and constructionpftha various parts 30101113 improved gasoline conserving power increasingvaporizer-may be made and substituted for those herein shown and described without departing from the spirit of ourjnvention the scope of which is set forth in the appended claims.
We claim as our invention:
1.- The combination with a carburetor, an engine cylinder block and crank case, of a duct leading;to-- the, carbureted air outlet from said carburetor, means for conducting moisture from the Water-jacket of said cylinder block to said duct, means for conducting oil; and oil vapor from the crank-case to said duct :and ,a, combined; oil =funnel, ventilator and :air filter: communicating with the chamber in said cram? case;
2. The combinationas set :forth in claim 1 with an- -oil trapin-the 3011 vapor-conducting means.-.
