INTERSECTED CONE-SHAPED AIR FILTER FOR AN AUTOMOTIVE INTERNAL COMBUSTION ENGINE

摘要

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).
