Abstract: A coupling arrangement for a drive train of a motor vehicle includes at least one clutch arranged on a rotating shaft in order to couple the rotating shaft selectively with a drive element of the drive train, and at least one activation device to activate the clutch. The activation device is adapted to bring an engagement segment selectively into engagement with a threaded segment rotating with the shaft in order to cause a relative movement of the engagement segment and the threaded segment along the axis of the rotating shaft and thus activate the clutch in the axial direction.

Abstract: An internal combustion engine with a device for controlled recirculation of exhaust gas into intake ducts via an exhaust gas recirculation line connected to the engine's exhaust system. Rapid response behaviour is achieved by providing an exhaust gas recirculation port in each intake duct in the immediate vicinity of the cylinders, which port communicates with a distributing device supplied via an exhaust gas recirculation line, and by providing the distributing device with an adjusting element which is configured to jointly control the flow cross-sections of the exhaust gas recirculation ports.
