An exhaust system for an internal combustion engine of a vehicle includes an exhaust gas pipe, at least one branch pipe branching off from the exhaust gas pipe, for example, a pressure pipe (22), as well as at least one support device (38) supporting at least one branch pipe in relation to an exhaust system component. The support device (38) includes a carrier element (42) fixed to the exhaust system component, a clamping element (44) pressing at least one pressure pipe (22) against the carrier element (42), as well as a clamping (tensioning) device (58) acting between the carrier element (42) and the clamping element (44) for tensioning the clamping element (44) in relation to the carrier element (42).

The proposed technology relates to an oxygen sensor for a vehicle, the oxygen sensor including a housing, a sleeve coupled to the housing, a sensor element configured to determine an oxygen concentration and provided within an inner space defined by the housing and the sleeve, a contact terminal connected to the sensor element, a contact bush including an upper bush and a lower bush, and a positioning unit coupled with the contact bush and maintaining a gap between a circumference of the contact bush and an inner side surface of the sleeve. In particular, the contact bush is coupled with the sensor element and the terminal at the center of the sleeve, and movement due to external impact is prevented.

An exhaust manifold apparatus for routing an exhaust gas produced by an internal combustion engine is described. The manifold includes a manifold log with a log wall that defines a log bore. The log bore is in fluid communication with an upstream opening of the manifold log and a downstream opening of the manifold log. An inlet runner includes a runner wall that defines a runner bore in fluid communication with the log bore. The inlet runner is engaged to the manifold log at a stress point, which also includes at least one stiffening rib disposed on an interior surface of the log wall and/or the inlet runner wall.

An open frontal area O (%) of the cells in the honeycomb structure body is 75 to 80%, a porosity P (%) of the partition wall measured by a mercury press-in method is 52 to 58%, an average pore diameter D (m) of the partition wall measured by the mercury press-in method is 6 to 12 m, and a pore volume rate A (%) of pores whose pore diameters are not less than 20 m with respect to an overall pore volume of the partition wall is not more than 13.5%.

An exhaust manifold for use with an internal combustion engine, the exhaust manifold including a body, one or more fluid passageways defined by the body, a valve in fluid communication with at least one of the one or more fluid passageways, the valve being adjustable between an open configuration and a closed configuration, a mounting bracket supported by the body, and an actuator in operable communication with the valve and configured to adjust the valve between the open and closed configurations, and wherein the actuator is coupled to the mounting bracket.

An injector for adding a liquid additive into an exhaust gas treatment apparatus includes at least one nozzle having a spray disc configured to inject the liquid additive into the exhaust gas treatment apparatus. The spray disc has: at least one spray duct, through which flow of the liquid additive can pass, the spray duct having an outlet opening configured to shape a spray jet of the liquid additive. The spray disc has a reinforcing structure arranged downstream of the outlet opening, the reinforcing structure being configured such that it is not wetted by the spray jet.

An exhaust gas treatment assembly comprises a housing which is radially inwardly deformed in a clamping region to retain a block of ceramic or other material which may be arranged as a filter or catalyst within the housing. The clamping region is deformed to a first surface level and includes local protuberances which extend radially outwardly to a second surface level and support a mounting surface for mounting the assembly in a mounting connector. The first surface level may vary to accommodate the dimensions of each individual block while the second surface level is fixed so that the mounting surface can fit in a mounting assembly with standardized dimensions.
