摘要： A method for manufacturing a vehicle muffler includes: forming a tubular body (6; 91, 92) from a nonwoven fabric (2; 2A, 2B) composed of inorganic fibers (11) each being in a filament form; inserting and installing the tubular body (6) as a sound-absorbing material into a space (S) between an inner pipe (72; 81) and an outer pipe (71; 821, 822) of an inner-outer double pipe constituting a vehicle muffler. The tubular body (6) may be obtained by applying a binder (3) to one surface (2a) of the nonwoven fabric (2), then rolling the nonwoven fabric (2) into a tubular shape with the surface (2a) having the binder (3) applied thereto facing inward, infiltrating additional binder (3) into an outer peripheral surface of the tubular-shaped nonwoven fabric (2), and then heating the tubular-shaped nonwoven fabric (2) to a predetermined temperature to harden the binder (3).

摘要： A method for producing a gasoline engine exhaust gas system having a particulate filter includes using at least one spacer for positioning at least two components provided for the passage of exhaust gas from the engine. The spacer includes ash-forming constituents. The method then includes permanently connecting the components, and burning the spacer element during a first heating up of the exhaust gas system, thereby releasing the ash-forming constituents and depositing the ash-forming constituents on the particulate filter. An exhaust gas system of a gasoline engine also is provided in a state before a first heating up of the exhaust gas system. The exhaust gas system includes a burnable spacer element between two exhaust gas system components that are provided for the passage of exhaust gas. The burnable spacer elements include ash-forming constituents.

摘要： A catalyst converter having a retaining mat with a thickness wherein the apparent density during assembling becomes 0.25 g/cm3 or more and less than 0.51 g/cm3 and the outside diameter D1 of a catalyst retainer is set according to interference of the retaining mat in passing through a press-in tool and interference of the retaining mat after being pressed into a retaining tube. The retaining mat is formed of a non-expandable inorganic fiber sheet. A pressing force moves the catalyst retainer in the axial direction with respect to the retaining tube while the catalyst converter device is used with the length L2 along the longitudinal direction of the catalyst retainer in the retaining mat wound around the catalyst retainer being set longer than the winding diameter D1 of the retaining mat around the catalyst retainer so that a retaining force R greater than the pressing force F can be secured.
