I 11v VENTOR w ROLA/VHFOX 9 AIR POLLUTION CONTROL UNIT FOR INTERNAL COMBUSTION ENGINES This invention relates to internal combustion engines; more particularly, to a unit to reduce air pollution that is caused by the expelling of exhaust gases from the tail pipe or pipes of an internal combustion engine in an automobile or the like although the invention can be adapted to any internal combustion engine regardless of its use.
For the benefit of those less experienced in the art of air pollution control it is first herein explained that in this invention the aforesaid unit consists of four separate devices which are connected together by tubes or the like, as will hereinafter be described. The aforesaid devices are an exhaust gas chamber, two vacuum separator tanks, and a third tank.
It is to be realized at this time that while I personally prefer to call this invention a Smog Control Unit I will hereinafter call it by the broad term that is more readily understood by all as an Air Pollution Control Unit. Air can be polluted by the exhaust gases coming from an internal combustion engine without necessarily producing smog as certain temperatures and other conditions of the air are needed before smog can be produced. It will be noted in the following specification of this invention that l have use the term emissions, this being due to the fact that emissions are defined in the dictionary as something emitted" and in this case the something is of course the exhaust gases of the internal combustion engine.
It is obviously the principal object of this invention to provide an air pollution control unit for internal combustion engines that will greatly reduce air pollution through the internal combustion engine exhaust emissions.
Another object of this invention is to provide an air pollution control unit for internal combustion engines that will eliminate the need for engine manufacturers to redesign their engines in order to reduce air pollution that is caused by the exhaust emissions of the engines.
Another object of this invention is to provide an air pollution control unit for internal combustion engines that will also permit the present fuels to continue to be used in internal combustion engines.
Another object of this invention is to provide an air pollution control unit for internal combustion engines, a unit that has neither moving parts nor does it require the use of chemicals in order to reduce air pollution caused by the exhaust emissions of the engines.
Still another object of this invention is to provide an air pollution control unit for internal combustion engines that can be installed on any internal combustion engine in a minimum of time and with a minimum of effort by nearly any mechanic or the like experienced either in the internal combustion engine or mechanical arts.
Other and further objects and advantages of this novel invention will no doubt come to mind as the reading of this specification and its appended claims proceeds and the accompanying drawings are examined in connection therewith.
In the drawings:
FIG. 1 is a semi-diagrammatic view of this invention in its entirety.
FIG. 2 is a longitudinally disposed sectional view of the exhaust gas chamber of this invention, taken substantially along line 22 of FIG. 1, and viewed in the direction indicated by the arrows.
In the two views of this invention, like parts of the invention are indicated by like reference numbers.
Directing ones attention first to FIG. 2 of the accompanying drawings it will be seen that the reference number 5 indicates that part of this invention which I call an exhaust gas chamber for want of a better name. The just mentioned exhaust gas chamber 5 consists of a cylindrical housing 6 in which are located three equally spaced and parallel cones 7 which can either be fabricated from sheet metal or the like. The aforesaid chamber 5 contains three equally spaced and parallel cones 8 which are fabricated from the same material as that of the aforesaid cones 7. Each cone 8 has a tubular member 9 secured in the apex thereof. Examination of FIG. 2 shows that the cones 7 are smaller in diameter than cones 8 to which their bottoms 10 are secured by any suitable means. Cones 8, which are nearest the tail pipe 11, have their bottoms secured to the periphery of the cylindrical housing 6 that is located in parallel spaced relation to the perforated plate 13. The space between the two plates 12 and 13 is filled with chromed ceramic balls 14, which, as a catalyst, oxidize the carbon monoxide to carbon dioxide and reduce nitrogen oxides to nitrogen. A capped opening 15, covered by cap 15A, is provided in the aforesaid housing 6 be tween the two perforated plates 12 and 13 in order to provide a means of placing the aforesaid balls I4 within this described exhaust gas chamber 5. A drain opening 16, covered by drain cap 16A, is located in theother side of the aforesaid housing 6.
Continuing to look at FIG. 2 of the drawings it will be seen that the just mentioned housing 6 is provided with three equally spaced and parallel perforated openings that are encompassed by upwardly extending tubular outlets 17 that are capped with end plates 18 (FIG. 1). Each tubular outlet is located at the base of one of the aforesaid sheet metal cones 8, as one can see by looking at the appended drawings. Acone-shaped tube 19, having an opening 20 inthe apex thereof, is located in each tubular outlet 17.
Before examining FIG. 1 of the accompanying drawings it should be realized that this FIG. 1 is called a semi-diagrammatic view since it is only an outline drawing. It is also because of the fact that the aforesaid exhaust gas chamber 5 is shown at ninety degrees to the other details of the invention for reasons of clarity. Also, the figure contains large outline arrows in the two vacuum separator tanks that show the direction of flow of the exhaust gases.
Directing ones attention now to FIG. 1 of the drawings it will be seen that the three aforesaid tubular outlets 17 are connected together by tubes and also that the outlet nearest the front end of the aforesaid exhaust gas chamber is connected by a tube 21 to the vacuum separator tank 22. The just mentioned tube 21 extends down through the top 23. of the tank 22, as one can see by looking at the previously mentioned FIG. 1. The rearmost one of the aforesaid outlets 17 is likewise connected by a tube 24 that extends down through the top 25 of the vacuum tank 26. A water and oxides discharge tube 27 extends downward from the bottom of the aforesaid vacuum separator tank 22, on through the top of the tank 28, which has a water drain off tube 29 extending downward from the bottom thereof. The aforesaid vacuum separator tank 26 is likewise provided with a water and oxides discharge tube 30 that also extends downward through the top of the aforesaid tank 28. Each discharge tube 27 and 30 has its lower end terminating in the upper end of a rubber tube 31, which has an elongated opening 32 therein and a plug 33 in the bottom thereof.
Still looking at FIG. 1 of the accompanying drawings it will be seen that the aforesaid vacuum separator tank 22 has a tube 34 extending outward from the top thereof to be suitably connected to the intake manifold of the internal combustion engine. This tube 34 is what I personally call a low velocity tube. A like tube 35, extends outward from the top of the aforesaid vacuum separator tank 26 to be suitably connected to the air cleaner of the engine. This tube is what I personally call a high velocity tube.
The only part of this novel invention that l have not so far mentioned is the tube 36 that extends outward from the front end 37 of the aforesaid exhaust gas chamber to be connected to the exhaust manifold of the internal combustion engine. The previously mentioned outlet pipe 11 extends outward from.the rear end 38 of the same aforesaid exhaust gas chamber 5 to replace the original stock muffler on the rear end of the outlet pipe l1 which may terminate in open air.
The way in which this novel invention works is quite simple-When the aforesaid internal combustion engine having this unit connected thereto is started, the exhaust emissions, consisting of unburned hydrocarbons, carbon monoxide, nitrogen oxides, sodium, sulphur, chlorides, lead, and acids deriving from sulfides flow through the aforesaid tube 36 on into the aforesaid exhaust gas chamber 5 which is provided with a plurality of open and closed trap cones, which I hereinbefore called cones 8 and 7 from whence the gases flow upward through the hydrocarbon receiver heads which for simplicity in this specification and its appended claims I have herein called the tubular outlets 17. From the outlets 17 the emissions .are drawn by vacuum through the aforesaidtubes 21 and 24 to the vacuum separator tanks 22 and 26, where the emissions are separated as indicated by the large arrows in FlG. l of the accompanying drawings. In the just mentioned tanks, the hydrocarbons are pulled off by vacuum and returned to the engine for reburning; the metal oxides and excess water are dropped out through the bottom of the often mentioned vacuum separator tanks 22 and 26 into the oxide trap which I have called a tank 28 in this specification and its appended claims. This tank contains a sponge or filter (not shown in the drawings) to trap the metal oxides. The water is drained off through the aforesaid water drain tube 29. The cycle through this invention is continuous, thus reducing the noxious content of the exhaust emissions before their final exit to the atmosphere through the aforesaid outlet pipe l l. The unit is designed to burn its own spoils over and over, using less atmospheric air. The unit does not require ari air pump to force in good clean air to reduce the amount of hydrocarbons going through the exhaust system of the engine.
This invention is subject to any and all changes in detail design and/or modifications that one may care to make in so long as the changes and/or modifications all fall within the scope and intent of the appended claims.
