AUXILIARY AIR-SUPPLY FOR INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent.
Patented Aug. 12, 1919.
Application filed July 16, 1917. Serial No. 180,888.
To all whom it may concern:
Be it known that I, JOHN J. Gooorr, acitizen of the United States, residing at Benton, in the county of Marshall and State of Kentucky, have invented certain new and useful Improvements in Auxiliary Air- Supplies for Internal-Combustion Engines,-
of which the following is a specification, reference being had to the accompanying 1o drawings.
This invention relates to internal combustion engines, and particularly to means for introducing auxiliary air into the intake manifold of an engine.
The general object of the invention is the provision of means whereby heated auxiliary air may be introduced into the intake manifold to mix with the fuel charge therein, thus putting the fuel charge into better working condition and increasing the power which may be obtained from the engine.
A further object in'this connection is to provide means whereby the amount of auxiliary air may be regulated and whereby the air may be heated by the exhaust of the engme.
A further object is to provide means whereby the engine may be primed to render starting easier in cold weather and whereby kerosene may be introduced while the engine is hot and running for the purpose of blowing out the carbon which may accumulate on the cylinder walls.
Other objects will appear in the course of the following description.
My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a portion of an automobile, the dashboard being in section and showing my device as applied thereto;
Fig. 2 is a fragmentary side elevation of the construction illustrated in Fig. 1 to show the manner of supporting the
Fig. 3 is a fragmentary section of the
pipe 12 and a portion of the pipe 15.
Fig. i is a perspective view of the clamp for supporting the
Referring to these drawings, 10 designates the several cylinders of an internal combustion engine of any ordinary type, and 11 the intake manifold thereof, 12 designating the exhaust manifold. All of these parts are constructed or arranged in any usual or ordinary manner. My attachment comprises a
pipe 13 which opens into the intake manifold 11 and extends upward therefrom and carries at its upper end the T 14. From one end of this T extends a pipe 15, which passes through the dash board 16 of a car and then 0 extends downward and extendsthrough the exhaust pipe 12. This pipe 15 is formed with a coil 17 and is also provided on the lnner face of the dash board or instrument board 16 with a " alve casing 18, havinga valve'19, whereby the flow of hot air passing from the exhaust manifold 12 may be carried to the intake manifold. The opposite end of the T is connected to a pipe 20, which extends to the inner face of the dash board or instrument board and then extends upward and is provided with a priming cup 21 controlled by the usual valve 22. The pipe 13 is held in upright position by means of a clamp 23, one end of which is engaged by one of the engine bolts.
In the practical use of this invention, the air entering the pipe 15 is heated by the exhaust and this hot air is drawn into the intake manifold upon the suction stroke of the piston and mixed with the charge coming from the carbureter, and from thence passes into the several cylinders in the usual manner. Inasmuch as this auxiliary air is heated, the gasolene or other fuel which has passed into the intake manifold is more highly vaporized and forms a more combustible and powerful gas, which will secure a maximum eX- plosive effect in the cylinders of the engine with a minimum amount of fuel. Thus increased mileage per gallon of fuel is secured. The amount of the air is regulated by the shut-off cock or valve 19, which is preferably arranged so as to secure a relatively wide range of regulation. By the use of the priming cup, gasolene may be used in the manifold at the same time that hot air is reduced and thus secure an easy starting of the machine, even in cold weather-and kerosene may also be vaporized by passing with the hot air into the intake manifold, thus cleaning out carbon.
It is to be noted that by the construction above described, I provide means whereby either cold air or hot air may be drawn into the
inlet manifold 11. Thus if the valve 19 be closed and the valve 22 be opened, cold air may be drawn into the manifold and if, on the other hand, this valve 22 be closed and the valve 19 opened, hot air will be drawn into the manifold and obviously if both valves be closed, the supply of auxiliary air will be cut off.
While I have illustrated a certain definite arrangement of the structure, I Wish it understood that various minor changes may be made in the details of construction and arrangement of parts, Without departing from the spirit of the invention.
Having described my invention, What I claim is r The combination with an internal combustion engine, provided with an intake manifold and an exhaust manifold, of a pipe opening at one end into the intake manifold, a T connected to the other end of said pipe, an air inducting pipe connected at one end to one branch of said T and leading rear- Wardly therefrom and then vertically downward and having its other end open and ex- 1 tending through the exhaust manifold and provided intermediate of its ends with a, controlling valve, said vertically extending portion of the conducting pipe having a coil to take up vibrations in said pipe, and another pipe connected at one end to another branch of the T, said last named pipe being provided at its opposite end with a valved priming cup, 'as and for the purpose set forth.
In testimony whereof I hereupon afiix my signature in the presence of two Witnesses.
