20100135773 | TURBOCHARGER HAVING A DEVICE FOR DETECTING A MALFUNCTION OF THE TURBOCHARGER AND A METHOD FOR DETECTING SUCH A MALFUNCTION - The turbocharger having a device for detecting a malfunction of the turbocharger, particularly a malfunction of at least one bearing of the turbocharger has the following features: The device for detecting a malfunction of the turbocharger has a memory device, in which the target operating states of an intact turbocharger are stored. The device for detecting a malfunction of the turbocharger further has a comparing device, in which the determined actual operating state of the turbocharger is compared to a corresponding target operating state of an intact turbocharger. The turbocharger further has a measuring device for determining an actual operating state of the turbocharger, wherein the device for detecting a malfunction of the turbocharger emits an error message if the comparing device detects that the actual operating stage deviates from the target operating state by a predefined measure. | 06-03-2010 |
20100139269 | TURBOCHARGED INTERNAL COMBUSTION ENGINE AND METHOD - A turbochargeable internal combustion engine contains a motor which has an exhaust manifold on the exhaust gas side, a turbocharger which has at least two turbocharger stages and, on the exhaust gas side, has an exhaust gas inlet and an exhaust gas outlet. The engine further has a primary catalytic converter, which is arranged on the exhaust gas side between the exhaust manifold of the engine block and the exhaust gas inlet of the turbocharger. | 06-10-2010 |
20100170245 | TURBOCHARGER CONFIGURATION AND TURBOCHARGEABLE INTERNAL COMBUSTION ENGINE - A turbocharger configuration, particularly in or for a motor vehicle, includes at least one turbocharger stage, which has a turbine and a compressor that are mechanically decoupled from each other. A turbochargeable internal combustion engine having such a turbocharger configuration, is also provided. | 07-08-2010 |
20100224809 | Method and Apparatus for Operating an Injection Valve - In order to operate an injection valve, a freewheeling operating state is controlled as the nozzle needle moves to its closing position, and a current through the coil is detected as a freewheeling current during freewheeling. As the nozzle needle moves to its closing position, a braking current pulse (I_BR) is generated on the basis of a time derivative (DI_DT_FW) of the freewheeling current and is impressed on the coil. | 09-09-2010 |
20100296920 | TURBOCHARGER COMPRISING A COOLING DEVICE AND AN OIL SUPPLY PIPE - A turbocharger, especially a turbocharger for a motor vehicle, has a turbine housing and a bearing housing. The turbine housing and the bearing housing are fitted with a common cooling device. The turbine housing includes a flange for attaching to an exhaust gas manifold. The flange is formed with a coolant inlet, a coolant outlet, and an oil supply pipe. | 11-25-2010 |
20120255297 | TURBINE FOR AN EXHAUST TURBOCHARGER, EXHAUST TURBOCHARGER, MOTOR VEHICLE AND METHOD FOR OPERATING AN EXHAUST TURBOCHARGER - A turbine for an exhaust turbocharger, in particular for a motor vehicle, has a turbine flap which controls an exhaust volume flowing through the turbine. A wastegate valve directs exhaust past the turbine and a wastegate flap controls an exhaust volume flowing through the wastegate valve. We also provide for an exhaust turbocharger, a motor vehicle having such an exhaust turbocharger, and for a method for operating such an exhaust turbocharger. | 10-11-2012 |
20130073187 | METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE, AND INTERNAL COMBUSTION ENGINE - A method for operating an internal combustion engine, having an exhaust gas turbocharger, during a load change of the internal combustion engine, includes initiation of a closing process of a throttle valve of the internal combustion engine, disposed in an induction tract or intake section of the internal combustion engine, as a function of an air pressure which is present upstream of the throttle valve, in such a way that the air pressure always falls short of a surge limit or pumping limit of a compressor, disposed in the induction tract, of the exhaust gas turbocharger. A staged or stepped reduction in a torque of the internal combustion engine is performed by shutting off fuel injections at predetermined cylinders of the internal combustion engine. An internal combustion engine with an exhaust gas turbocharger is also provided. | 03-21-2013 |
20130291539 | EXHAUST-GAS TURBOCHARGER HAVING A COMPRESSOR HOUSING WITH AN INTEGRATED WASTEGATE ACTUATOR - An exhaust gas turbocharger has a compressor housing formed with a fresh-air inlet duct. An electric wastegate actuator is integrated into the compressor housing. The electric wastegate actuator is thermally coupled to the fresh-air inlet duct. | 11-07-2013 |
