| 20090120405 | System with a Compressor and with a Consumer in a Motor Vehicle - A system has a compressor and a consumer which are coupled to a drivetrain and extract energy through the drivetrain. The consumer is suitable for varying an absorption of power, which is made available to it by the drivetrain, as a function of a power which is required for compressor operation and which is supplied from the drivetrain to the compressor. A pump has at least one pump chamber which generates a pumping power during pumping operation. The pump additionally has at least one pump chamber which generates no pumping power or a reduced pumping power during pumping operation. | 05-14-2009 |
| 20090235663 | Device and Method for Supplying Fresh Air to a Turbocharged Reciprocating-Piston Internal Combustion Engine - A device for fresh-gas supply for a turbocharged, compression-ignition, reciprocating-piston internal-combustion engine is provided. The engine has fresh-gas supply pipe and exhaust gas manifold pipe, between which an EGR device is installed. A tubular inside space section of the fresh-gas supply pipe located downstream of a turbocharger has a compressed-air connection with a volume control device, and a butterfly valve for controlling throughflow. Operation of the butterfly valve is controlled by an electronic control unit of the engine which processes sensor signals. A control valve of the EGR device, which is electronically controlled and controls the exhaust gas throughflow volume, is connected to the electronic control unit for synchronized operation of the butterfly valve with the volume control device. | 09-24-2009 |

| 20100228464 | Method and Device for Controlling a Suction Pressure of an Internal Combustion Engine - A method device for controlling a suction pressure of an internal combustion engine, particularly a diesel engine having an exhaust gas turbocharger. The compressor is connected to a suction line of the internal combustion engine via an actuating section having an actuating element for changing a cross-section of the actuating section. In the first step, the current suction pressure in the suction line of the internal combustion engine is determined. A compressor pressure of the compressor is determined by pressure sensors and compared to the suction pressure. Values corresponding to current operating data of the internal combustion engine are identified and an actuation signal is generated using a controller, based on the comparison; and changing the cross-section of the actuating section is adjusted by adjusting the actuating element using the actuating signals. | 09-09-2010 |
