Abstract: An exhaust system assembly including a catalyst housing, a catalyst core, and a swirler tube positioned inside the catalyst housing. The swirler tube has a plurality of openings that permit radial exhaust flow into an inner volume of the swirler tube from the catalyst housing. One end of the swirler tube has blades that extend inward and include oblique surfaces arranged at oblique angles relative to a centerline axis of the swirler tube. These blades induce a vortex in the exhaust gases exiting the first swirler tube end. The swirler tube is arranged inside the catalyst housing such that a sequential flow path is created where the exhaust gases flowing through the catalyst housing must first pass through the openings in the swirler tube and then by the blades at the first swirler tube end.

Abstract: A shock absorber pressure tube defining a working chamber is provided. A piston assembly coupled to a piston rod is slidably disposed in the pressure tube and divides the working chamber into upper and lower working chambers. A reserve tube surrounds the pressure tube to define a reserve chamber. A base valve assembly, position at one end of the pressure tube, controls fluid flow between the lower working chamber and the reserve chamber. The reserve tube comprises first and second open shells that are joined together at longitudinal seams to create a substantially cylindrical shape. The first and second open shells may be made from patchwork blanks, tailor welded blanks, tailor rolled blanks, or tailor heat treated blanks to give different portions of the first and second open shells different thicknesses, strengths, properties, or characteristics.

Abstract: An accumulator includes a housing, a flexible bladder and a support. The housing includes a chamber having a defined volume and a passage extending through the housing. The flexible bladder is positioned within the chamber and contains a compressible gas. The bladder being operable in an expanded condition and a partially collapsed condition. The support is positioned in the chamber and engages the flexible bladder when the flexible bladder is in the expanded condition. Liquid is positioned in the chamber and in contact with the flexible bladder. A volume of the liquid within the chamber is at a minimum when the flexible bladder is in the expanded condition. The volume of liquid within the chamber increases as a pressure of the liquid increases to compress the gas and operate the flexible bladder in the partially collapsed condition.

Abstract: A vehicle exhaust system includes a tubular component having an inner surface and an outer surface such that the inner surface defines a primary exhaust gas flow path. The tubular component extends along a central axis from an inlet end to an outlet end. The tubular component includes at least one ridge extending at least partly along a circumference of the tubular component. The at least one ridge includes a first portion angularly extending inwardly from the tubular component, and a second portion disposed downstream of the first portion. The second portion angularly extends inwardly from the tubular component. In some cases, the second portion defines a plurality of openings extending therethrough and spaced apart from each other. In some cases, the tubular component defines a plurality of tube openings disposed downstream of the at least one ridge.

Abstract: A damper with inner and outer tubes and a piston slidably disposed within the inner tube to define first and second working chambers. A collector chamber is positioned outside the outer tube. An external control valve is positioned in fluid communication with the collector chamber. An intake valve assembly, mounted to one end of the inner tube, includes an intake valve body, intake passages, and intake valve. The intake valve body abuts the outer tube to define an accumulation chamber positioned between the intake valve assembly and a closed end of the outer tube. The accumulation chamber is arranged in fluid communication with the collector chamber. The intake valve body forms a fluid-tight partition between the accumulation chamber and a fluid transport chamber is positioned between the inner and outer tubes. The intake valve controls fluid flow between the accumulation chamber and the second working chamber through the intake passages.

Abstract: An exhaust component for a motor vehicle includes a wall, an internal volume, an inlet, and an outlet. The wall includes a core layer having a surface and a first layer disposed on a portion of the surface. The portion is less than 100 percent of an area of the surface. The core layer has a first composition. The first layer is a cold-sprayed layer. The core layer has a second composition different from the first composition. The first layer reduces surface-radiated noise from the exhaust component during operation of the motor vehicle. The internal volume is at least partially defined by the wall. The inlet is in fluid communication with the internal volume. The outlet is in fluid communication with the internal volume.
