| 20110252795 | TWO-STAGE TURBOCHARGER ASSEMBLY - A two-stage turbocharger assembly for an internal combustion engine is provided. The assembly has a low pressure turbocharger, and more than two high pressure turbochargers arranged in parallel with each other. The compressor outlet of the low pressure turbocharger is operatively connected to the compressor inlets of the high pressure turbochargers. The turbine outlets of the high pressure turbochargers are operatively connected to the turbine inlet of the low pressure turbocharger. | 10-20-2011 |
| 20110008151 | TURBINE AND METHOD FOR CLEANING TURBINE BLADES UNDER OPERATION CONDITIONS - A method for cleaning a number of turbine blades of a turbine under operation conditions by means of a cleaning fluid which is sprayed onto the turbine blades by a number of nozzles is disclosed. The method is characterised in that the cleaning fluid is distributed to the nozzles such that only a fraction of the nozzles is used at any one time to spray the cleaning fluid onto the turbine blades. Furthermore, a turbine comprising a number of rotor blades, a number of stator blades and a number of nozzles is described. Each nozzle is connected to a cleaning fluid supply. The turbine further comprises at least one distribution unit which is configured such that the cleaning fluid can be distributed to only a fraction of the nozzles at any one time. Moreover, a turbocharger comprising an inventive turbine is disclosed. | 01-13-2011 |
| 20100322781 | IMPELLER AND TURBOCHARGER - An impeller having a rotation axis, a radial direction, a backplate and a number of vanes which are connected to the backplate at a line of connection is provided. Each vane has an upstream side, a downstream side and an outer side. The downstream side of each vane has an edge portion which is located near the outer side. The vanes project radially over the backplate and the downstream side further includes a connecting portion connecting the edge portion to the backplate and including an angle with the radial direction. The connecting portion includes a convex rounded portion which is located near the line of connection. Moreover, a turbocharger having an inventive impeller is disclosed. | 12-23-2010 |
| 20100215506 | IMPELLER COATING - An impeller is provided with a back surface that is at least partly coated with a thermal barrier coating. The thermal barrier coating includes an anodized layer, polymer or polymer-based ceramics. | 08-26-2010 |
| 20090104024 | Air intake for a turbocharger for an internal combustion engine - Disclosed is an air intake for a turbocharger for an internal combustion engine, said air intake including a series of variable position guide vanes for directing the air such that it is swirling in a rotational sense on reaching the impeller of the compressor of the turbocharger. The variable position guide vanes are made comprised of sound absorbent material such as to achieve a substantial reduction in turbocharger noise at the air intake. | 04-23-2009 |
