AIR GUIDED FILTER FOR INTERNAL COMBUSTION ENGINE

Abstract: The present invention discloses an air guided filter arranged integrally with air filter and is called as air guided filter. The object of invention is to improve internal combustion engine performance without changing basic construction of the engine. The improvement encompasses only the action of changing the existing air filter with air filter according to the present invention. The user of air guided filter will make air flowing into combustion chamber stay clean since air s filtered and guided in such a way that quality of air and fuel mixed will be better. The combustion in the internal combustion chamber will thus be improved.

Description: Description AIR GUIDED FILTER FOR INTERNAL COMBUSTION ENGINE Technical Field of Invention The present invention relates to air filter used for an internal combustion engine, particularly air filter provided with air guide which directs and air flowing uniformly passes through the filter. Background of Invention Nowadays, the internal combustion engine is designed to have a high performance such as a high power resulted in a better combustion. Such better combustion will thus produce an optimal power and unharmful combustion residue to the environment . Internal combustion engine at present is of ample use for driving means in agriculture engines, industrial devices and electric generators. Environmental factor and optimality of fuel per unit power consumed by the internal combustion engine will be improved as well when combustion of mixed fuel and air in the internal combustion chamber can be improved. Improved combustion mixture of air and fuel can be achieved when air to be mixed with fuel has met certain condition. One among the ways to improve the combustion is fuel and air mixture quality in an internal combustion chamber prior to combustion must be homogenously mixed and dispersed in the internal combustion chamber. The improvement cited above can be economically achieved by merely substituting the air filter of the engine for an air filter having been equipped with an air guide, not by redesigning the whole construction of the engine. Summary of the Invention Based on the reasons disclosed earlier, it is designed a device which can improve the combustion quality of air and fuel mixture in an internal combustion engine. The device is integrally arranged with an air filter and is called as air guided filter. The object of invention is to improve internal combustion engine performance without changing basic construction of the engine. The improvement encompasses only the action of changing the existing air filter with air filter according to the present invention. By using the air filter equipped with an air guide, the air flowing into combustion chamber stays clean since it has been filtered and guided in such a way that quality of the air and fuel mixed will be better. The combustion in the internal combustion chamber will thus be improved. Brief explanation of the drawings Further detail of invention can be obtained from the following description aided by the enclosed drawings. Figure 1A illustrates top view of an air filter on which an air guide is attached on the outer part of filter paper with the two ends of the air guide are bound by a supporting ring. Figure IB illustrates cross-sectional view of air filter shown in Figure 1A. Figure 2A illustrates top view of an on which an air guide is attached on the inner part of the air filter with the two ends of the air guide are bound by supporting ring. Figure 2B illustrates cross-sectional view of air filter as in Figure 2A; Figure 3A is a top view of air filter having air guide when fixed in the inner filter paper forming elevation angle with supported ring . Figure 3B illustrates cross-sectional view of air filter as in Figure 3A; Figures 4A and 4B illustrates shape and direction of uniform holes of air guide according to the present invention; Figure 5 illustrates an air guide that is attached to air filter having square shape not cylindrical as generally made ; and Figure 6 illustrates diagramatically position of air filter in the internal combustion engine according to the present invention. Disclosure of Invention Referring to Figures 1A and IB, air guide (5) can be placed on the outer part of inner part of air filter (1) or, on Figure 2, on the inner part of air filter (1) . Air guide (5) of air filter (1) is placed parallel to the corrugated filter paper (6) with upper and lower portions thereof are attached on filter support ring (4) . Air guide (5) can be placed in the inner part of filter (as shown in Figures 2A and 2B) , or on the outer part of the air filter (Figure 1A and IB) depending upon the required design of the air filter. With air guide (5) attached to air filter (5) at present, air flowing into manifold (2) wil be in the same direction. When air guide (5) is elevated with cerrtain elevation angle (8) , air flowing into the filter will be guided as well as rotated. Rotated air will create mixing effect when mixed with fuel such that the mixtures will be uniform. The mixtures of air and fuel uniformly mixed when combusted in combustion chamber, will create an improved combustion, for which it will sequently increase internal combustion engine performance. Air guiding (5) according to the present invention, can be made from materials such as metal plate or other materials formed halves cones cross-section holes (7) in the face. As shown in Figure 4, measurement and space between pores are made uniform at the face of air guide (5) . Shape of halves cones cross-section (7) will force air to form grooves, and direction of holes will define air flows direction. When the holes are in the same direction and uniform, the grooves formed will be in the same direction and uniform such that air flowing into air channel (2) will be in the same direction and uniform. Direction of the grooves are defined by direction of the holes and also elevation angle (8) of air guide (5) with respect to support ring (4) of air filter (1) , since support ring (4) of air filter (1) generally forms rectangular with air channel (2) . Since air guide (5) can be made of materials relatively rigid in air filter, it can strengthen construction of air filter (1) as well as function as air guide. Air guide (5) can be placed in varieties shapes of air filter (1) of internal combustion engine, for example air guide (5) as shown in Figure 5, can be placed in air filter (1) which has square shape having certain elevation angle to the face of air filter (1) . Such installed variations do not decrease function and advantage of air guide (5) of said air filter (5) . Figure 6 shows diagram of position of air filter (1) in the internal combustion engine, which is placed before manifold (2) and combustion chamber (3) of the engine.
