AIR GUIDED FILTER FOR INTERNAL COMBUSTION ENGINE =—J
Field of the Invention
The present invention relates to an air filter used in an internal combustion engine, and particularly, to an air filter provided with an air guide which directs air for uniform passage through the filter.
Background of Invention
Nowadays, internal combustion engines are designed to have high performance, such as high power resulting from better combustion. Such better combustion produces an optimal power and unharmful combustion residue to the environment.
Internal combustion engines at present are of ample use as driving means in agriculture machinery, industrial devices and electric generators.
Environmental factors and optimality of fuel per unit power consumed by an internal combustion engine, as well as combustion of mixed fuel and air in the combustion chamber of an internal combustion engine can be improved. Improved combustion mixture of air and fuel can be achieved when air to be mixed with fuel has met certain conditions.
One way to improve the combustion is homogeneously mix and disperse the fuel and air mixture quality in an internal combustion chamber prior to combustion.
Thus there is a need for a device wherein the improvement cited above can be economically achieved without having to redesign the construction of the engine.

Detailed Description
In an internal combustion engine an air filter 1 is placed before 15 a manifold or air channel 2 and a combustion chamber 3 of an engine, as for example shown schematically in Fig 6. Referring to Figs 1A and IB, an air guide 5 is placed on the outer part of an air filter 1 or, on Fig 2, on the inner part of air filter 1. The air guide 5 of the air filter 1 is placed parallel to the pleated filter paper 6 with 20 upper and lower portions thereof are attached on filter support ring
4. Air guide 5 may be placed in the inner part of the air filter (figs 2A and 2B), or on the outer part of the air filter (Figs 1A and IB) depending upon the required design of the filter.
With air guide 5 being attached to the air filter 1 in accordance 25 with an exemplary embodiment of the present invention, air flowing into an air channel 2 will be directed in the same direction. When air guide 5 is elevated to a certain elevation angle 8, the air flowing into the filter will be guided as well as rotated. The rotated air creates a mixing effect when mixed with fuel such that the mixtures are
6
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.
The air guide 5, according to the present invention, may be made from material such as a metal plate or other suitable materials having depressions 12 having half-cone cross-sectional shapes which define a plurality of holes 7 disposed along their faces. As shown in Figs 4A, 4B' and 4B", the depressions 12 are uniformly dispersed 10 along the face of the air guide 5. The half-cone cross-sectional shaped depressions 12 force air flowing through the holes 7 to form columns or columnar flow, and the direction of the holes will define the direction of air flow. When the holes are in the same direction and uniform, the columns formed will be in the same direction and 15 uniform such that air flowing into the air channel 2 will be in the same direction and uniform. The direction of the columns are defined by the direction of the holes and the elevation angle 8 (see Figs 1C, 2C and 3C) of the air guide 5 with respect to the support ring 4 of the air filter 1.
Since the air guide 5 may be made of materials rigid relative the materials used to form the air filter, it may strengthen the construction of the air filter 1, as well as function as an air guide.
The air guide may can be placed in a variety air filters having different shapes. For example, the air guide 5, as shown in Figs 5A, 25 5B and 5C, may be placed in an air filter 1 having a square-shape and at a certain elevation angle in relation to the face of the air filter. Such installed variations do not decrease the function and advantages of the air guide of the present invention.
