Patented Sept. 29, 1953 BOOSTER DEVICE FOR INTERNAL- COIVIBUSTION ENGINES Alphonse Kraus, Rochester-,1. Y.
Application July 20, 1946, SerialNo. 685,072
4 Claims. (Cl. 123'-119) the type of boosting agents employed for this pur-- pose are set forth hereinbelow.
The object of the invention differs from other boosters in the simplicity of both its individual elements and overall structure, as also in its mode of operation and functioning;
The booster device and the boosting agents of this invention will improve ordinary engine performance, will permit good engine operationwith even low-cost fuels of low octane rating, and
will maintain good engine performance under difficult operating conditions. Moreover, the
booster device will permit the introduction of varying amounts of boosting agent into the enine during its operation, and it further makes possible the adaptation of a number of such sub- Stances which heretofore could not be readily and effectively employed for boosting purposes;
It is therefore an object of this invention to provide a device effecting the delivery of substances, separately from the motor fuel proper, into an internal combustion engine, and the delivery and vaporization of said substances within the intake assembly of an internal combustion engine.
A further object of this invention is to employ said substances as boosting agents and to reduce or eliminate engine knock.
Another object is to employ, together with the booster device, substances that will act to reduce the content of the more highly toxic constituents of present common engine exhaust gases.
Still another object is to provide for the. introducing of varying quantities of the aforesaid substances into the engine during its operation, in response to the various operating requirements and by means of the booster deviceof the invention.
Still other objects will appear. as presented hereinbelow.
These objects are accomplished by the following invention:
First, by the simple construction and arrangement of a booster device and parts thereof, and by their several or individual combination with the assembly of an internal combustion engine,
Such as described hereinafter and presented, in principle, in the accompanying drawing forming part hereof; and
Second, by providing substances, and means and processes for delivering them into an internal combustion engine, and further meansfor vaporizing said substances within the air-intake assembly of an internal combustion engine.
In the figure of the drawing forming part hereof, a partly cross-sectional and partly diagrammatic front elevation of a basic form of the device of the invention is shown in combinationwith an air filter and an air-intake conduit of an internal combustion engine.
Referring to the figure of the drawing, tank I, provided for theboosting agent fluid, has an outlet 2, which is joined to a delivery tube 3 with a flow control mechanism 4. Extension 5 V of delivery tube 3 is secured to container 6 of air-intake filter lypa'sses through the filter housing 6 into the intake conduit 8, its outlet ll terminating above a non-absorbent screen 9, which may also take the form of a permeable pad or filter pack, held in place by support ID;
concentrically spaced and, arranged with tube 3 is tube l2v provided for the delivery of a second booster fluid into the engine. The outlet [3 of tube l2; together with the outlet II of tube 5, forms a jet or spray-type atomizing nozzle which terminates above screen 9. Tube H, as shown, represents the terminal delivery section of a second booster assembly, the construction of which is composed of elements similar or equivalent to those employed for the delivery into the engine of the boosting agent fluid contained in tank I for this reason, the additional elements of this second booster assembly are not shown.
In practicing the invention in accordance withv the device, arrangement and combination shown in the figure of the aforesaid drawing, the boost.- ing agent fluid in tank I is permitted, to flow by gravity or forced action through outlet 2 and delivery tube 3 and its outlet l l. of extension 5. upon.
screen 9 into the engine intake conduit 8. Passage of the boosting agent through screen 9 aids infurther dispersing and. vaporizing the boosting, agent, and admixing it with the intake air and the intake fuel charge.
and 1. Pad, screen or filter 9 in conduit 8 is preferably made of a, nonabsorbent and noncorroding material, of open mesh, offering only slight.
The intake air is. drawn into, conduit 8 through. filter elements 6- boosting agent is adjusted in conformance with engine operating requirements. Delivery tube 3 and its extension 5 can be connected by means of a coupling, which is not shown. Screen 9 is held in place in conduit 8 by means of support element In.
A second booster component, complementary to that introduced into the engine through booster outlet H, can be introduced into the engine through tube I2 and its outlet I3, which together with outlet I I of tube 5 forms a jet-type assembly for dispersing, atomizing and admixing the injected boosting agent in the intake air and the fuel charge, although other types of spray pieces and atomizing mechanisms may be employed for this purpose. The process of dispersing, admixing and vaporizing the intake mixture is further aided by screen 9. The how of the second booster component is regulated either by means of a separate flow control mechanism, not shown, or by means of the flow control mechanism 4. In the latter case, tube i2 and its connection with the respective booster fluid supply tank are joined to the said mechanism l. The boosting agent component delivered through the tube l2 may, if required, be preheated in known manner.
Boosting agents employed generally comprise aliphatic and aromatic substances, solutions and mixtures of such, and anhydrous and aqueous components thereof, which are readily dispersed and volatilized in the engine intake system in combination with the booster device and which, individually or in given combination, possess antiknock, or antiknock and oxidizing properties,
such as further described in a divisional application, Serial No. 318,730, filed November 4, 1952.
In modified forms of the device and process of the invention, and in accordance therewith, the delivery tube extension assemblies and outlets thereof of the booster device may be introduced through the wall of the air-intake shaft of the engine at a point below the air-intake filter container 6 and above screen 9.
In other modified forms or the device of the invention, and in accordance therewith, two or more booster assemblies as herein described may be combined to produce the effect and results of the invention, the flow control being eifected either separately or jointly by mechanisms 4.
In another combination, the outlets of two or more delivery tubes, controlled either separately or jointly by mechanisms 4 and provided with an atomizer jet assembly, may be introduced at a given angle through an opening in the wall of the air-intake shaft. Furthermore, in accordance with the invention, instead of introducing the booster charge into the intake air at a point prior to its mixing with the fuel proper, the boosting agent may also be introduced directly into the air-fuel mixture either at a given point in a precombustion chamber, or at the point and jointly with the entry of the air-fuel mixture into the combustion chamber, or given booster charges may be simultaneously introduced at all or the said points.
In still further combinations and modifications of the device of the invention, the booster device may be connected to cooperate with superchargers as such, and the boosting agents may be forcibly injected into the assembly of the internal combustion engine.
In its simplest form, a further modification of the booster device of the invention may consist of a supply tank, a feed-line outlet thereof, a flow control mechanism for said feed-line, a spray or atomizing mechanism for the terminal outlet of the said feed-line, and a screen element for the further dispersal of the boosting agent in the engine intake assembly, the said terminal feedline outlet being introduced into the engine at any of the points indicated hereinbefore.
