Patent number: 6923841Abstract: A filter element of an air filter includes a main body and a substrate. The far infrared emission powder substances are embedded at certain grain sized and at certain ratio to the substrate, thereby forming the main body that is adapted in form to various internal combustion engines. The resonance effect will be created by means of the far infrared emission substances in the filter element of the air filter, thereby making tiny the molecular cluster of water in the moisture-containing air entering into the internal combustion engine for combustion, increasing the molecular freedom, enlarging the contact surface of the oil gas with the air. Therefore, it's easier that the oxygen-containing particles and the oil gas are evenly mixed for reaching an optimal mixture ratio of the original design standard.Type: GrantFiled: May 19, 2003Date of Patent: August 2, 2005Inventor: Tung-Sen Chen

Patent number: 6656243Abstract: A filtered air vent has a housing with an inlet and outlet, at least one set of spaced apart airflow control elements extending across the housing elements, spaces between the elements, and a pleated filter disposed within the housing. The filter has alternating first and second pleats that open up in opposite first and second directions, respectively. In one exemplary embodiment of the invention, at least a portion of the pleats that open in a first one of the directions are disposed across the spaces between the elements. The filter may be made from a washable filter material such as, for example, woven polypropylene. The elements in one embodiment of the invention are rotatable blades of a damper disposed within the housing and each of the blades are disposed within a corresponding one of the pleats that open in the second direction.Type: GrantFiled: February 6, 2002Date of Patent: December 2, 2003Inventor: Joseph Hodge
