A turbocharger supplying air to an internal combustion engine is controlled to minimise the difference between the actual air mass rate fed to the engine, and the desired air mass rate determined from the current engine operating point. Preferably, the turbocharger is protected from overspeed and excess turbine inlet temperature, with the protection modes having higher priority than the performance control mode. The turbo speed is checked at 302, and, if excessive, the bypass is adjusted at 304 to reduce the turbo speed. If the turbo speed is below limits, the turbo inlet temperature is checked at 312, and, if excessive, the bypass is adjusted at 314. If, after either adjustment has been made, the limits are still exceeded, then the fuelling is derated at 308.

Verfahren zum Steuern des Betriebs eines Kompressors (22), der zum Zuführen von aufgeladener Luft zu einem Verbrennungsmotor (10) angeordnet ist, wobei das Verfahren ein Verändern und ein Festlegen einer maximalen zulässigen Kompressorauslasstemperatur auf der Basis einer Funktion der Kompressorauslasstemperatur und der Betriebszeit, ein Erzeugen einer Ladedruckgrenze auf der Basis der festgelegten maximalen zulässigen Kompressorauslasstemperatur und das Steuern des Betriebs des Kompressors (22) auf der Basis der Ladedruckgrenze so, dass die festgelegte maximale zulässige Kompressorauslasstemperatur nicht überschritten wird, umfasst.

Turbolader.

Turbolader, mit einer Turbine (1) zur Entspannung eines ersten Mediums, mit einem Verdichter zur Verdichtung eines zweiten Mediums unter Nutzung von in der Turbine bei Entspannung des ersten Mediums gewonnener Energie, wobei die Turbine (1) ein Turbinengehäuse (3) mit einem Turbinenzuströmgehäuse (4) und einen Turbinenrotor (6) aufweist, wobei der Verdichter ein Verdichtergehäuse und einen mit dem Turbinenrotor (6) über eine Welle (7) gekoppelten Verdichterrotor aufweist, wobei das Turbinengehäuse (3) und das Verdichtergehäuse jeweils mit einem zwischen denselben angeordneten Lagergehäuse (2), in welchem die Welle (7) gelagert ist, verbunden sind, und wobei das Turbinenzuströmgehäuse (4) derart spiralartig, einstückig und doppelwandig ausgebildet ist, dass zwischen einer äußeren Wand (15) des Turbinenzuströmgehäuses (4) und einer inneren Wand (16) des Turbinenzuströmgehäuses (4) ein Wasserkanal (17) zur Führung von Kühlwasser ausgebildet ist, und dass sich an die den Wasserkanal (17) begrenzende, innere Wand (16) des Turbinenzuströmgehäuses (4) an einer vom Wasserkanal (17) abgewandten Seite der inneren Wand (16) ein Führungskanal (18) des zu entspannenden ersten Mediums unmittelbar anschließt.
