摘要： The invention relates to a high-speed impeller for delivering gaseous or liquid media, for example as a compressor wheel for an exhaust-gas turbocharger. The high-speed impeller has a reinforcing core structure and an outer functional section. The invention is distinguished by the fact that reinforcing sleeves are pushed concentrically over one another for producing the core structure, in which case the length of the respective reinforcing sleeves varies. Furthermore, the functional section is cast onto the core structure.

摘要： An exhaust-gas turbocharger for an internal combustion engine includes an exhaust-gas turbine in the exhaust section and a compressor in the intake tract. The compressor includes a compressor impeller in an inflow passage in the compressor housing. Furthermore, there is an auxiliary-air feed device, which is assigned to the compressor region and has an auxiliary-air passage, in the compressor housing for supplying auxiliary air, which can be introduced via an injection opening in the wall of the inflow passage of the compressor into the flow-facing region of the compressor impeller.

摘要： An exhaust gas turbocharger with an exhaust gas turbine and a radial compressor includes an impeller which pumps air through guide vanes or wedge guide elements into a helical passage. It is proposed that the guide vanes or wedge vane elements be guided for axial displacement in the casing of the radial compressor and be able to be shifted across the pumped stream of the impeller.

摘要： An internal-combustion engine has an engine braking device which has brake valves by way of which the combustion chamber content of the cylinders can be diverted in the engine braking phase. In the engine braking operation, the brake valves are changed into the opening position. In order to increase the operational reliability of the engine braking device, a blocking device is provided which acts upon the brake valves and which can be adjusted between a holding position and a release position. In the holding position of the blocking device, the brake valves are held in the opening position.

摘要： In order to increase the operating reliability by means of simple measures in a method for operating a supercharged internal combustion engine which has two exhaust-gas turbochargers arranged in parallel, in each case only one exhaust-gas turbocharger is actively put into operation, the actual value of a characteristic quantity is measured and is compared with a predeterminable desired value, and, in the event of an inadmissible deviation of the actual value from the desired value, a change-over is made between the exhaust-gas turbochargers by means of the control signal.
