Abstract: In a turbine for an exhaust gas turbocharger of an internal combustion engine having a housing part with accommodation space including a turbine wheel and at least one spiral channel via which exhaust gas of the internal combustion engine may flow. The spiral channel has an outlet cross-section via which the turbine wheel accommodated in the accommodation space may be acted on by the exhaust gas, and has at least one blocking member, which is connected to an adjusting part so as to be movable hereby in the peripheral direction of the accommodation space for adjusting the outlet cross-section (AR, ARλ, AR,RGR). A bypass duct is provided, via, which exhaust gas can bypass the turbine wheel and whose flow cross-section is also adjustable by the blocking member moved the adjusting part.

Abstract: An internal combustion engine has first and second combustion chambers, first and second exhaust gas line elements, and an exhaust gas turbocharger which has a first flood, a second flood, and a third flood. A bypass device has a bypass line that can be flowed through by exhaust gas from the first and second exhaust gas line elements and via the bypass line a turbine wheel is bypassed by a first part of the exhaust gas from the first and second exhaust gas line elements. A valve device includes a first valve element, via which an amount of the exhaust gas flowing through the bypass line and bypassing the turbine wheel from the first and second exhaust gas line elements is settable. A third exhaust gas line element opens out into the third flood.
