Abstract: A mixer arrangement for an exhaust gas system, having an inlet opening through which an exhaust gas mass flow (A) can be guided, and a mixer for swirling the exhaust gas, which has at least one inflow opening that is fluidically connected to the inlet opening, wherein at least one first portion (A1) of the exhaust gas mass flow (A) can be guided through the mixer via the at least one inflow opening, an injection device by means of which an additive can be injected, and a bypass having at least one throughflow opening which is fluidically connected to the inlet opening and through which a second portion (A2) of the exhaust gas mass flow (A) can be guided past the mixer, there being provided at least one regulating body by means of which a flow cross-section Q in the mixer arrangement can be varied such that a ratio V with (formula I) can be varied.
