Patented Sept. 8, 1931 UNITED STATES PATENT @FFECE CARBON REMOVER AND ELIMINATOR Application filed April 25,

The present invention relates to attachments for internal combustion engines and the primary object of the invention is to provide an improved humidifier for admitting water vapor into the explosive mixture for reducing carbon formation.

A further object of the invention is to provide a carbon remover and eliminator attachment embodying a sealed vapor generating chamber having an outlet connection with the intake manifold of the engine.

A further object of the invention is to provide a device of this character which will allow engine to function properly at various engine speeds without requiring any adjustment or inclusion of any moving parts.

A further object of the invention is to provide a device of this character embodying a generating tank of novel construction whereby damage due to freezing is eliminated and thus permitting use of the device in cold climates. Y

A still further object of the invention resides in the provision of a device of this character which may be readily applied to the exhaust manifold of conventional types of internal combustion engines and embody- .ing a novel construction whereby dry steam will be admitted to the intake manifold of the engine.

Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken in con nection with the accompanying drawings forming a part of this specification and in which drawings:

Figure 1 is a fragmentary side elevation of an internal combustion engine and showing the device applied thereto.

Figure 2 is an enlarged section on line 22 of Figure 1.

Figure 3 is an enlarged longitudinal section thru the vaporizer.

In the drawings, and wherein similar reference characters designate corresponding parts thruout the several views, the letter A may designate a conventional type of internal combustion engine and B the humidifier for supplying vapor to the intake mani- 50 fold of the engine A.

I for preventing 1930. Serial No. 447,282.

The internal combustion engine A includes the usual exhaust manifold 5 and the intake manifold 6 for conveying the explosive charge from the carburetor 7 to the combustion chambers of the engine.

The humidifier l3 embodies a vaporizing tank 8 of special design and which tank is adapted to be mounted upon the upper side of the exhaust manifold 5 as by a suitable band 9. The tank 8 may be formed of any suitable non rusting metal and is formed with a flat bottom or base wall 10 from the ends of which are upwardly flaring end walls 11 and from the side edges of which are the upwardly flaring or diverging side walls 12. The flat bottom wall 10 is of substantially rectangular shape having its greatest length extending between the upwardly flaring end walls 11. Closing the upper end of the tank 8 is a top wall 14 having its edges sealed to the upper edges of the walls 11 and 12.

Extending upwardly from the top wall 14 adjacent one end thereof is a threaded neck 15 providing a filler opening and which neck removably receives a threaded closure cap 16.

Mounted in one of the sloping end walls 11, adjacent the upper end thereof is an overflow valve 18 for regulating the liquid level in the tank during the filling operation. In filling the tank 8 with water, the cap 16 is removed for allowing the water to enter the tank thru the neck 15, and during this filling operation the valve 18 is preferably opened filling of the tank beyond a point spaced slightly below the top wall 14. After the tank is filled to the proper level the cap 16 is replaced and the valve 18 closed.

Provided in the top wall 14 adjacent the opposite end of the tank from the neck 15 is a relatively small outlet opening 20 for escape of steam generated in the tank.

Arranged over the outlet opening 20 and sealed to the top wall 14; is a steam dome 22 preferably of tubular formation and of a diameter considerably greater than the small outlet opening 20. The chamber formed by the dome 22 receives the steam generated in the reservoir 8 and the small outlet opening 20 prevents any great amount of water in the reservoir from splashing into the chamber of the steam dome.

Connected at one end into the top of the dome 22 is a feed tube 25 the opposite end of which is connected into the intake manifold 6 by a suitable coupling nipple 26. Thus it will be seen that steam from the dome 22 is conveyed by the tube 25 to the intake manifold 26 for mixing with the explosive charge generated in the carburetor 7.

It will now be noted that the device is air tight with the exception of the opening into the intake manifold 6 and that no air is permitted to enter the vaporizing tank during operation of the engine. Thru this air tight arrangement, there is no need of adjustments being necessary for tuning up the engine since no additional air supply is admitted into the intake manifold thru the feed tube 25. Steam from the dome 22 will be forced by pressure in the dome thru the feed tube 25 and will also be aided intravel thru the feed tube by the suction in the intake manilVhile in the example shown the bottom wall 10 of the reservoir or vaporizing tank 8 is' shown as being flat for surface contact with the flat upperwall of the exhaust manifold 5 it will readily be apparent that the bottom wall 1 0 may be of difierentshapes such as arcuate or the like for snugly fitting upon various types of exhaust manifolds. In some instances, the tank 8 may be cast as an integral part of the exhaust manifold.

The upwardly sloping end and side walls 11 and 12 respectively will prevent damage to the reservoir thru freezing of the water in the reservoir, since should the liquid in the reservoir freeze the frozen mass is permitted to expand and rise in the tank without damage to the tank. This feature is extremely desirable in that it permits use of the device in subzero weather without any danger of damage to the vaporizing tank. Since as before stated, the valve 18 should be opened when filling the tank, an air space will be formed above the liquid in the tank and will allow for expansion of the liquid should such freeze. It will also be apparent that the air tight feature prevents uneven running of the engine even tho all of the water is exhausted from the tank 8 in that no additional air supply is admitted to the intake manifold.

From the foregoing it will be apparent that a novel and simple device of this character has been provided which may be readily mounted upon various types of internal combustion engines for admitting vapor into the explosive charge for the engine. It will also be apparent that the special design of the vaporizing tank permits use of the device in cold climates without danger of damaging the tank d-ueto freezing of the liquid therein.

Changes in detail may be made to the form of invention. herein shown and described,

without departing from the spirit of the invention-or the scope of the following claims.
