Patent number: 7263826Abstract: A muffler device with catalysts for improving purifying exhaust gas of nitrogen oxides within a motorcycle exhaust pipe comprises a muffler divided into three chambers, a first chamber, a second chamber, and a third chamber; a front exhaust pipe; a front reduction catalyst; a rear exhaust pipe provided with a secondary air inlet behind the reduction catalyst for introducing secondary air therein. Thereby, the exhaust gas from an engine with air-to-fuel ratio less than or equal to 14.7 will firstly pass the reduction catalyst to have its nitrogen oxides (NOX) effectively inverted into nitrogen (N2) and oxygen (O2), and then secondary air will be added to the exhaust gas so as to increase its air-to-fuel ratio to larger than 14.7, and finally the exhaust gas will pass the oxidation catalyst to have its carbon monoxide (CO) and hydrocarbons (HC) effectively inverted into carbon dioxide (CO2) and water (H2O).Type: GrantFiled: December 12, 2005Date of Patent: September 4, 2007Assignee: Sentec E&E Co., Ltd.Inventor: Hsiao Chung Wu

Patent number: 4382487Abstract: The invention relates to an exhaust muffler made of enamelled sheet steel, which is composed of a plurality of structural parts in which the structural parts of the muffler are coated with enamel slick, are then put together and heated to enamelling temperature, with the contacting surfaces of the structural parts thus fusing and in that way being securely connected together. Such structural parts include two head pieces provided with connection pipes which are positioned on the exhaust muffler sheath, as well as sound absorbing elements disposed inside the muffler. The head pieces and the sound absorbing elements arranged on the inside of the sheath, are connected with the sheath by means of connection surfaces located on the peripheral edges of the head pieces and the sound absorbing elements which are bent over parallel to the wall of the sheath. Between these various surfaces enamel slick is applied, whereby these members are connected together upon firing.Type: GrantFiled: December 30, 1980Date of Patent: May 10, 1983Inventor: Werner Baumann
