S P E C I F I C A T I O N A MULTI-PURPOSE ANTI-AIR POLLUTION DEVICE

This invention relates in general to internal combustion engine accessories, but more particularly to a multi-purpose anti-air pollution device, It is of common knowledge now that one of the causes of air pollution comes from the internal combustion engine. If we research further on the study of pollution that comes from the engine, pollution originated from carbon. Carbon comes from the unburned gasoline and the unburned gasoline comes from the excess gasoline. When the engine of the vehicle functions although the vehicle is not running, the engine is undoubtedly consuming gasoline. At this instance the butterfly valve is almost closed and a strong suction to the intake manifold develops thus excess of waste gasoline exists. When the vehicle is running at a minimum speed of less than 40 kilometers per hour, the rpm of the engine is very high. When it stops, the accelerator is released and the butterfly valve closes . At this point the suction at the intake manifold increases resulting to more usage of gasoline. Changing gears during driving also results in wasting of gasoline. In all instances whenever the accelerator is released, the existence of waste gasoline, unburned gasoline carbon, pollution or carbon monoxide cannot be avoided. In addressing these problems, catalytic converters were introduced. These catalytic converters, however, only add pollution to the environment since the catalysts (platinum, or Rhodium) have to be discarded as waste after its purpose has been served. Furthermore, it is well known that there converters are very expensive, hence, the very purpose of economy or reducing- the cost of gasoline usage is defeated. It is therefore the primary object of this invention to provided an anti-pollution device that automatically reduces the suction of gasoline during idling by as much as 10%, such that waste of gasoline is minimized.. Still an object of this invention is to provide an anti-pollution device wherein carbon monoxide emission is minimized by reducing the excess or waste gasoline during idling of an internal combustion engine. Another object of this invention is to provide an anti-pollution device which reduces air-pollut±on at the same time acts as an economizer, saving fuel as much as 50% of its consumption . Moreover, an object of this invention is to provide an anti-pollution device that acts as a power booster, gasoline saver and an anti-pollutant rolled in to one. These and other objects and advantages will come to view and be understood upon a reading of the detailed description when taken in conjunction with the accompanying drawings, wherein: Figure 1 is a perspective view of the present invention for an anti-pollution device; Figure 2 is a sectional view taken along line 2-2 of Figure 1 ; Figure 3 is a sectional view taken along line 3-3 of Figure 1 ; and Figure 4 is sectional view taken along- line 4-4 of Figure 1. Referring now to the several views of the drawing wherein like reference numerals designates same parts throughout, there is shown an invention for a multipurpose anti-air pollution device generally designated as reference numeral 10. Said anti-pollution device 10 comprises a tubular member 11 having a perforated end portion 12, a front cavity 14 formed within and along the perforated end portion 12 of said tubular member 11, a filtering element 13 disposed in said front cavity 14, an air passage 15 co-axially disposed in said tubular member 11 communicating said front cavity 14 on one end to the rear cavity 16 provided at the opposing end thereof, and a front cap 40 screwably closing the front cavity 14 of said tubular member 11. Said front cavity 14, rear cavity 16 and air passage 15 form a straight line . An outlet pipe 17 is screwably and perpendicularly provided to the rear end of said tubulair member 11 in communication with the rear cavity 16. Trie upper end of said outlet pipe 17 is connected with a hose (not shown) which leads to the intake manifold of an internal combustion engine. Through the far end of said tubular member 11, a plug valve 18 is rotatably fitted to said rear cavity 16. Said plug valve 18 is provided with a shaft portion 19 that extends inwardly compressing a spring biased against the end portion of said air passage L5. Said shaft portion 19 has an angular passage 20 disposed on its forward end. Said angular passage 20 has a horizontal portion 21 disposed forwardly and communicating with said rear cavity 16 and a vertical portion 22 extending upwardly from the opposing end thereof to communicate with said plug valve 18. The shaft portion 19 of the plug valve 18 has a circumferential groove 25 which is locked Joy set screw 26 screwably provided beneath t tubular member- 11. Screwably and perpendicularly connected to the front cavity 14 of the tubular member; 11 is a by-pass assembly 28, which is being defined Jby a pipe 29 having an enlarged upper bore 30 therein and a reduced lower bore 31 extending downwardly of said upper bore 30 towards the lower end of said pipe 29. Within said enlarged upper bore 30 is a spring biased valve member 32. Said valve member 32 has its lower tip 23 seated on the upper end of the reduced lower bore 31. The upper opposing end of said pipe 29 is screwably enclosed loγ a retainer nut 34. A tubular branch 35 is provided in between connecting the pipe 29 of the by-pass-assembly 28 and the outlet pipe 17. Said tubular branch 35 connects the air passage 23 of the outlet pipe 17 and the enlarged bore 30

*of the by-pass assembly 28. The by-pass assembly absorbs tremendous supply of air coming from the perforated wall and transmits them to the outlet pipe. A central plug valve 37 is fitted perpendicularly within a transverse position at a portion of the air passage 15 of the tubular member 11. a transverse hole 39 is provided on the shaft portion 40 of the central plug valve which is selectively communicating with the air passage 15 by rotating the knolo portion 41 of the plug valve 37. This shaft portion 40 has a circumferential groove 42 provided thereon which is interlocked by a pin 43 through a hole 44 beneath the tubular member 11. When the engine starts running, the engine intake manifold starts to such air from the device. The central plug valve 37 is adjusted so tiiat the transverse hole 39 of its shaft portion is aligned, with the cavities and the air passage of the outlet pipe. Air enters the tubular member through the perforated end wall and filtered by the filtering element thereon. This allows the influx of fresh air into the cylinders of the engine and reduces the vacuum therein during various driving conditions such as starting, stopping and acceleration such, that suction of air and fuel mixture through the carburetor is reduced.
