An exhaust gas heater, for an internal combustion engine exhaust system, includes a support () with an outer circumferential area (), arranged radially outside in relation to a heater longitudinal axis (A), and a central area (). A heating conductor () is carried at the support and includes a helically wound heating section () on a first axial side () of the support. The central area is axially offset in a direction of the first axial side of the support in relation to the outer circumferential area such that a radially outer end section of the heating section, which outer end section is located in the area of the outer circumferential area of the support, and a radially inner end section () of the heating section, which inner end section is located in the area of the central area of the support, are axially offset in relation to one another.

Exhaust gas heater

A mixer mixes exhaust gas (A) flowing in an exhaust gas-carrying duct of an internal combustion engine with reactant (R) injected into the exhaust gas-carrying duct. The mixer includes a mixer body () with a reactant-receiving duct () as well as a releasing device () with a releasing duct (). The releasing device adjoins the reactant-receiving duct () in a transition area () and leads away from the reactant-receiving duct. The releasing device () has an asymmetric configuration in relation to a longitudinal axis (LR) of the reactant-receiving duct.

Mixer

A mixer mixes exhaust gas (A) flowing in an exhaust gas-carrying duct of an internal combustion engine with reactant (R) injected into the exhaust gas-carrying duct. The mixer includes a mixer body () with a reactant receiving duct (), an exhaust gas inlet opening arrangement () with a plurality of exhaust gas inlet openings () leading to the reactant receiving duct, and at least one release duct () leading away from the reactant receiving duct () with a release duct opening () for the release of a reactant/exhaust gas mixture from the mixer body ().
