Abstract
A mixer apparatus for an exhaust gas aftertreatment system of a motor vehicle. The apparatus includes a housing having enveloping, first end, and second end walls. An injection opening for an exhaust gas aftertreatment agent is in the enveloping wall. An inlet opening is in the first end wall. The injection opening is configured for mounting a metering module. A rectilinear metering axis, which extends through the metering module and corresponds to an injection direction of exhaust gas aftertreatment agent injected into the housing, tangentially contacts, at a contact point, a theoretical cylinder, disposed in the housing, having a variable radius and a cylinder axis that is congruent with a central axis of the housing. A region of the metering axis extending from the injection opening to the contact point is located, with respect to inflowing exhaust gas, in the shelter of an opening-free region of the first end wall.
