Abstract: Exhaust gas from a first outlet port (5) of a cylinder (3) of a combustion engine (2) can flow through the first turbocharger (7), and exhaust gas from a second outlet port (6) of the cylinder (3) can flow through the second turbocharger (17). A first connecting duct (28) can supply the second turbine (19) with exhaust gas from the first turbine (9). The first connecting duct (28) is connected to a first bypass duct (29) that issues into a tailpipe line (32) downstream of the second turbine (19) to bypass the second turbine (19). The first bypass duct (29) has a second control valve (44) that can block the first bypass duct (29). The first connecting duct (28) has a first control valve (43) that can block the first connecting duct (28) to prevent exhaust gas from flowing through the first turbine (9) to the second turbine (19).

Abstract: A method for setting a clutch torque between an engine and a drive of a vehicle during a starting process of the vehicle includes increasing the clutch torque during a first phase, limiting the clutch torque to a first torque value during the first phase, and further increasing the clutch torque in a second phase after an engine rotational speed reaches a rotational speed limit.

Abstract: A method for operating an internal combustion engine (10) that has at least one cylinder row (11a, 11b) with first and second exhaust-gas turbochargers (13a, 13b; 14a, 14b). Charge air is provided by the first exhaust-gas turbocharger (13a, 13b) in single-charger operation, but is provided by the first and second exhaust-gas turbocharger (13a, 13b; 14a, 14b) in two-charger operation. To switch from single-charger to two-charger operation above a load threshold value of the internal combustion engine (10), when a speed of the internal combustion engine (10) reaches or overshoots a threshold value, a charge pressure is increased to build up a torque reserve and a charge pressure reserve and to maintain a driver demand torque. When the charge pressure reaches or overshoots a threshold value, a switch is made from single-charger operation to two-charger operation, and subsequently, the torque reserve and the charge pressure reserve are eliminated.

Abstract: A motor vehicle (1) has a wheel arch (3), in which a wheel (4) is arranged, and has an air guiding apparatus (20) for guiding an air flow (8) that flows onto the wheel arch (3) during operation of the motor vehicle. The air guiding apparatus (20) is configured and arranged in such a way that a first part air flow (11) is guided past an inner side of the wheel (4) and a second part air flow (12) is guided past an outer side of the wheel (4). The two part air flows (11, 12) then are combined again behind the wheel arch (3) in a vehicle longitudinal direction.

Abstract: The articulated shaft has an axial securing means which includes a securing ring which has a spring prestress and acts on the articulated shaft via a connecting device of the articulated shaft to a housing cover of a joint housing. It is provided, in particular, that the housing cover is made of aluminum, on which a bearing disk made from steel lies which supports the prestressed securing ring on the outer side. This arrangement avoids it being possible for the securing ring to bury itself into the housing cover made from aluminum and a greater play being produced and the axial securing action no longer being ensured.

Abstract: A ventilation system for a motor vehicle, having a multiplicity of controllable air outlets, an input unit for selecting at least one flow target position in a passenger compartment of the motor vehicle from a multiplicity of selectable flow target positions. The selectable flow target positions can be displayed on a display unit, a control unit which is connected to the input unit and to the air outlets and is designed to set an outflow direction of at least one of the air outlets on the basis of at least one selected flow target position. In this context, at least two of the selectable flow target positions on the display unit are combined to form a flow target region with little draft.
