20130213019 | EXHAUST GAS TREATMENT UNIT FOR AN EXHAUST GAS RECIRCULATION LINE AND INTERNAL COMBUSTION ENGINE AND MOTOR VEHICLE HAVING AN EXHAUST-GAS TREATMENT UNIT - An exhaust gas treatment unit includes a substantially cylindrical exhaust gas treatment body having a main axis and, on at least one opening side of the exhaust gas treatment unit, at least one of the following connecting devices or connectors: an offset compression zone or a molded structure for form-locking engagement. An internal combustion engine includes at least one exhaust gas treatment unit and at least one exhaust gas conducting line. The at least one exhaust gas treatment unit is completely introduced in the at least one exhaust gas conducting line. A motor vehicle having at least one exhaust-gas treatment unit is also provided. | 08-22-2013 |
20130219869 | DEVICE FOR CONVEYING LIQUID REDUCING AGENT AND MOTOR VEHICLE HAVING THE DEVICE - A device for conveying a liquid reducing agent from a tank to a supply element includes a connecting element for connecting a reducing agent line, a system heating unit and a heat-conducting structure configured to transport heat from the system heating unit to the connecting element. A motor vehicle having the device is also provided. | 08-29-2013 |
20130228231 | MOUNTING FOR AN INJECTOR AND INJECTOR DEVICE HAVING AN INJECTOR INTEGRATED IN THE MOUNTING - A mounting for an injector includes at least one main body and a cap jointly or commonly forming a receptacle for the injector. The main body is formed of metal sheets which are connected to each other and together form at least one annular chamber which extends around the receptacle. In particular, a mounting for an injector is provided, which has a simple technical construction and can be cooled (optionally in a controlled manner). Moreover, the mounting has a particularly lightweight construction and is adapted to operation with considerable temperature differences. An injection device integrated in a mounting is also provided. | 09-05-2013 |
20130232954 | METHOD FOR OPERATING A METERING APPARATUS, METERING APPARATUS AND MOTOR VEHICLE HAVING A METERING APPARATUS - A method for operating a metering apparatus for reducing agent includes providing the metering apparatus with at least one movable pump element movable between upper and lower reversal points to convey reducing agent into an exhaust-gas treatment component, and at least one position transmitter for determining a pass of the movable pump element. In the method, a first detection of a position of the movable pump element is provided by the position encoder. Subsequently, the movable pump element is moved and reducing agent is metered into the exhaust-gas treatment component. Thereupon, a second detection of a position of the movable pump element is provided by the position encoder, and subsequently a first quantity of reducing agent which is metered between the first and second detections is determined. A metering apparatus and a motor vehicle having a metering apparatus are also provided. | 09-12-2013 |
20130232957 | DELIVERY UNIT FOR A LIQUID ADDITIVE, METHOD FOR OPERATING A DELIVERY UNIT AND MOTOR VEHICLE HAVING A DELIVERY UNIT - A delivery unit for a liquid additive includes a first pump with a first suction port and a first pressure port, a second pump with a second suction port and a second pressure port, and a feed device. The feed device is connected to the first pressure port through a first line system and the first suction port is connected to a tank for the liquid additive through a second line system. The second pressure port is connected to the tank through a third line system and the second line system and the third line system are separated from one another. A method for operating a delivery unit and a motor vehicle having a delivery unit are also provided. | 09-12-2013 |
20130255235 | METHOD FOR OPERATING AN EXHAUST-GAS TREATMENT DEVICE AND MOTOR VEHICLE HAVING THE DEVICE - A method for operating an exhaust gas treatment device having at least one heater and at least one supply device for a reducing agent includes initially carrying out a test in order to determine if the reducing agent is to be supplied, and subsequently implementing different heating strategies in each case. In the event that the reducing agent is to be supplied, the exhaust gas treatment device is heated with the heater until a first threshold temperature is reached, if a first temperature lies below the first threshold temperature. In the case when no reducing agent is to be fed, the exhaust gas treatment device is heated with the heater until a second threshold temperature is reached, if a second temperature lies below the second threshold temperature. A motor vehicle having the device is also provided. | 10-03-2013 |
