Abstract: An internal combustion engine for a motor vehicle includes an exhaust system through which exhaust gas can flow and in which a first exhaust gas aftertreatment element is disposed. An exhaust gas turbocharger has a turbine and the turbine has a turbine wheel which is disposed upstream of the first exhaust gas aftertreatment element. A bypass line bypasses the turbine wheel and via the bypass line at least part of the exhaust gas can bypass the turbine wheel. The bypass line also bypasses the first exhaust gas aftertreatment element. The bypass line is fluidically connected to the exhaust system at a branch point disposed upstream of the turbine wheel and upstream of the first exhaust gas aftertreatment element. The bypass line is fluidically connected to the exhaust system at a discharge point disposed downstream of the turbine wheel and downstream of the first exhaust gas aftertreatment element.

Abstract: A method for operating an internal combustion engine having a cylinder, an intake valve, an air pipe, and a valve element disposed in the air pipe, includes detecting a signal for causing a fuel supply of the cylinder to switch off. The valve element is moved out of a first position into a second position triggering a lower flow cross-section while the fuel supply is still activated, where a first cam for actuating the intake valve is allocated to the intake valve. While the fuel supply is still activated, switching from the first cam to a second cam and via the second cam the intake valve is actuated such that the intake valve causes a reduced air intake. An exhaust cam shaft for actuating an exhaust valve is set in an advance direction such that a valve intersection of the intake valve and of the exhaust valve ceases.

Abstract: A valve drive device has a camshaft which includes a shaft element and a cam piece which can be driven by the shaft element and a first cam effecting a first stroke of a valve and a second cam effecting a second stroke of the valve, and is displaceable in the axial direction of the camshaft relative to the shaft element between a first position, in which the valve can be actuated by the first cam, and a second position in which the valve can be actuated by the second cam, and has an electrically controllable actuator via which the cam piece is displaceable relative to the shaft element in the axial direction as a result of an electrical control of the actuator. The actuator pushes the cam piece alternately back and forth between the positions in the case of successive electrical controls occurring with the same polarity.

Abstract: A method for operating a reciprocating piston internal combustion engine in an engine braking mode includes moving an outlet valve of a first cylinder for a first time into a closed position, subsequently for a first time into an open position, subsequently in a direction of the closed position, and subsequently for a second time into the open position. The outlet valve is held open during the moving in the direction of the closed position for such a long time that the first cylinder is filled with gas which flows via an outlet duct out of a second cylinder. The outlet valve is moved, during the moving in the direction of the closed position, into an intermediate position which lies between the open position and the closed position, where from the intermediate position the outlet valve is moved for the second time into the open position.
