Heaters can also be provided to heat the circulating air.Type: GrantFiled: February 29, 2000Date of Patent: October 15, 2002Assignee: Kairos, L.L.C.Inventor: Joe Ford

Patent number: 5580368Abstract: An exhaust gas cleaning device is provided, which is simple in structure and offers good performance in the cleaning of exhaust gas from car engines. The cleaning device includes a conductive cylindrical body through which the exhaust gas passes. A shaft is installed at the center of the conductive cylindrical body. A set of blades is provided on the shaft acting as a fan for sucking the exhaust gas in and out of the conductive cylindrical body. A scraping knife is provided also on the shaft. A static-electric generator having one pole connected to the cylindrical body and the other pole connected to the shaft is used to create an electric field between the cylindrical body and the shaft that ionizes smoke particles in the exhaust gas and deposits them on the inner wall of the cylindrical body. A collecting chamber is provided in communication with the inside of the cylindrical body for collecting deposition of smoke particles scraped by the scraping knife off the inner wall of the cylindrical body.Type: GrantFiled: February 22, 1995Date of Patent: December 3, 1996Assignee: Su-Ying R. LuInventor: Shui T. Lu

Patent number: 5263317Abstract: Disclosed is an exhaust gas purifying apparatus for an automobile diesel engine including a pair of electrodes disposed at a predetermined interval in an exhaust path of an automobile diesel engine, and a high voltage power source for applying a high voltage to the pair of electrodes whereby an electric field is generated in a space between the pair of electrodes so as to collect diesel particulates. Since the diesel particulates emitted from a diesel engine are charged heavily in negative, and since the exhaust gas purifying apparatus forms an electric field between the pair of electrodes, the diesel particulates are collected on one of the pair of electrodes.Type: GrantFiled: September 29, 1992Date of Patent: November 23, 1993Assignee: Kabushiki Kaisha Nagao KogyoInventors: Shigeo Watanabe, Katsuharu Kinoshita, Niichi Hayashi, Hisashi Matsunaga
