Abstract
This invention relates to an intersected cone-shaped air filter (1) for focusing air flow within an automotive internal combustion engine which substantially comprises a hollow body (2) of specified thickness whose side dips 2 DEG to 7 DEG with respect to vertical axis, and a clamping ring (3) which is fixedly disposed along the outer periphery of the upper and the lower ends of the filter body (2) for strengthening the filter body construction. The air filter body is made up of symmetric longitudinally folded filter paper materials whose thickness governs that of the air filter body (2).

Description
INTERSECTED CONE-SHAPED AIR FILTER FOR AN AUTOMOTIVE INTERNAL COMBUSTION ENGINE
Technical Field of Invention
This invention relates to an air filter, particularly an intersected cone-shaped air filter that can focus airflow into an outomotive internal combustion engine.
Background of Invention
Current automotive technology needs automotive engines of high performance. A highly performanced automotive engine requires that fuel must be proportionately mixed with clean air and the mixture produced can quickly reach the internal combustion charge. There are two options for the accomplishment of the conditions cited above. The first is to minimize fluid friction, and the second one is to exert a driving force on the mixture. It can be performed only by designing appropriately the aerodynamic construction of the air filter.
The object of this invention is thus to provide an air filter wherein a driving force is performed due to the focusing of the airflow on the midmost streamline. Based on its shape, i.e., intersected cone, the air filter is referred to CYCLO FILTER.
Brief Description of the Invention
This intersected cone-shaped air filter is designed for the purpose of filtering the air flowing into an automotive internal combustion engine and focusing it to the midmost streamline. Due to its intersected conical shape, the effective area of this air filter's cylindrical surface is
advantegously larger than that of previously adapted filters .
The larger the effective area of this air filter's cylindrical surface is, the more the mass of the air-fuel mixture that will flow into the combustion chamber. And the driving force resulted in due to the focusing of air flow on the midmost streamline will increase the velocity and the mass of the air-fuel mixture within the combustion chamber. Consequently, it will be generated by the automotive engine.

Figure 2a is a perspective view of the modification of the air filter presently invented with body being partially opened. Figure 2b is a longitudinal cross section along line A' -A' of the embodiement in shown in Figure 2a.
Figure 3 is a schematic diagram showing the path of the airflow from the atmosphere into an automotive internal combustion engine.
Detailed Description of the Invention
Figure la and lb show a basic construction of an intersected cone-shaped air filter (1) comprising a hollow body (2) of specified thickness the side of which dips downwardly 2° to 7° with respect to vertical axis. The filter body is made up of symmetric longitudinally folded filter paper materials whose thickness governs the thickness of the air filter body (2) . A clamping ring (3) is fixedly disposed along the outer periphery of the upper and the lower ends of the filter body (2) for strengthening the filter body construction.
Figure 2a and 2b show the one of the modifications of the cone-shaped air filter, which have specifics hollow body
(2 ' ) . The outer wall body of the air filter shape is cylindrical and the inner wall body of the air filter shape is intersected cone.
Figure 3 is a schematic diagram showing the path of the air flow from the atmosphere into an automotive internal combustion engine. Air from the atmosphere is directed to an air filter (I) through the air filter body. Owing to the shape of the filter, the air flows through the centre of the smaller end of the filter into the mixing chamber (II) . The air and fuel which have become air-fuel mixture after entering the mixing chamber, flows further into the combustion engine (III) . The driving force resulted in due to the focusing of the airflow on the centre of the smaller end of the filter will increase the velocity and the mass of the air-fuel mixture within the combustion chamber.
The preferred embodiments described within this specification are intended only for illustration, not to limit the scope of invention. Modification of any kind is always possible for them skilled in the art as long as it is still within the scope of invention and claim.
