Abstract: An exhaust gas treatment arrangement for an exhaust gas system of an internal combustion engine includes at least one electrically excitable heating unit having a heating region arranged in an exhaust gas guiding housing such that exhaust gas can flow thereover, and two connection regions passing through the exhaust gas guiding housing for connection to electrical connection lines running outside the exhaust gas guiding housing. A connection line installation aid is fixed with respect to the exhaust gas guiding housing and has at least one connection line positioning recess in an installation aid body for receiving a connection line to be connected to one of the connection regions.

Abstract: An exhaust system for an internal combustion engine includes an exhaust gas heater housing, an exhaust gas heater disposed in the exhaust gas heater housing and an exhaust gas treatment unit housing which, via an upstream end region, adjoins a downstream end region of the exhaust gas heater housing. At least one exhaust gas treatment unit is disposed in the exhaust gas treatment unit housing. At least one exhaust gas heater includes at least one connector element that, in the downstream direction toward the exhaust gas treatment unit housing, extends toward the exhaust gas heater and, in an exhaust gas primary flow direction, overlaps with the upstream end region of the exhaust gas treatment unit housing and/or with an exhaust gas treatment unit disposed in the upstream end region of the exhaust gas treatment unit housing.

Abstract: A probe carrier arrangement, especially for an exhaust system of an internal combustion engine, includes a probe socket (14) provided at a probe carrier body (12). The probe socket (14) has at least one insert-receiving opening (24) extending in a direction of an insert-receiving opening longitudinal axis (E). A probe carrier insert (28) is arranged in the insert-receiving opening (24). The probe carrier insert (28) has at least one probe-receiving opening (36) extending in a direction of a probe-receiving opening longitudinal axis (S).

Abstract: A mounting assembly unit includes a mounting element (12) to be fixed by at least one fastening bolt (30). At least one mounting element passage opening (14, 16) is provided in the mounting element (12) for the passage of the at least one fastening bolt (30). A mounting aid unit (18a, 18b) associated with at least one mounting element passage opening (14, 16) is provided at the mounting element (12). The mounting aid unit (18a, 18b) associated with the mounting element passage opening (14, 16) has a mounting aid unit passage opening (22a, 22b), which is positioned aligned with respect to the mounting element passage opening, such that an edge area (28a, 28b of the mounting aid unit (18a, 18b), which edge area surrounds the mounting aid unit passage opening (22a, 22b), is arranged overlapping the mounting element passage opening (14, 16) in some areas.

Abstract: A connection unit connects an electrical supply line to a connection element of a heatable exhaust gas system. The connection unit has a housing having a connection element receiving region extending in the direction of a first housing axis (G1) and a supply line receiving region extending in the direction of a second housing axis (G2). The connection element receiving region is open in a first axial connection element receiving region end region for receiving the connection element protruding from an exhaust gas system and is closed off in a second axial connection element receiving region end region. The supply line receiving region is open to the connection element receiving region in a first axial supply line receiving region end region and is open in a second supply line receiving region end region for receiving an electrical supply line.
