摘要:
An exhaust gas aftertreatment installment and associated exhaust gas aftertreatment method utilizes a nitrogen oxide storage catalytic converter and an SCR catalytic converter. A particulate filter is provided upstream of the nitrogen oxide storage catalytic converter or between the latter and the SCR catalytic converter or downstream of the SCR catalytic converter. The time of regeneration operating phases of the nitrogen oxide storage catalytic converter can be determined as a function of the nitrogen oxide content of the exhaust gas downstream of the nitrogen oxide storage catalytic converter or of the SCR catalytic converter and/or as a function of the ammonia loading of the latter. Moreover, a desired ammonia generation quantity can be determined for a respective regeneration operating phase. The installation and method are adopted for use for motor vehicle internal combustion engines and other engines which are operated predominantly in lean-burn mode.

An arrangement of a windscreen wiper system with an associated windscreen washer system on a motor vehicle is provided. The windscreen washer system includes a washer fluid supply line to which are connected, downstream of a branch point, at least two distribution lines leading to respective outlets. The outlets can be moved together with a corresponding wiper arm of the windscreen wiper system. A distributing device can control an emergence of washer fluid from at least one of the outlets. The distributing device can be located in an engine compartment or stowage space of the motor vehicle.

For various reasons, it can be desirable to subject fuel cells to drying procedures. In solid polymer electrolyte fuel cells for instance, drying may be carried out prior to storing at below freezing temperatures, or to recover cell performance lost following freeze/thaw events. An improved drying method involves drying the cell uniformly throughout. That is, the drying power over the length of the fuel cell is adjusted to be essentially uniform. This can be accomplished by using an appropriate set of operating conditions. The improved drying method can improve the lifetime of the fuel cell.

A method for controlling a powertrain comprising an electro-mechanical transmission mechanically-operatively coupled to an engine and an electric machine adapted to selectively transmit mechanical power to an output member through selective application of a plurality of torque-transfer clutches includes monitoring a clutch slip speed, synchronizing an oncoming clutch, and constraining reactive clutch torque limits for the oncoming clutch to achieve a reactive clutch torque that is less than an estimated clutch torque capacity.

An electrode for an electrochemical energy accumulator includes a catalyst layer, where the catalyst layer includes an electrically conductive matrix and a chemically active material which is intercalated into the electrically conductive matrix. A protective coating is disposed on the catalyst layer, where the protective coating includes at least one metal oxide and methionine.

A pole cap for a battery pole of a battery has a sleeve-like contacting portion, which has an outer periphery widening conically in the direction of the battery pole and tapering conically in the direction of the battery pole. A terminal is formed as a double-walled terminal sleeve having an inner wall and an outer wall, both designed to be supported by a collar, where the walls form an annular gap for positively receiving the sleeve-like contacting portion of the pole cap and where the gap tapers in the direction of the collar.

A method and device for the remote control of a function of a vehicle is disclosed. Images of the vehicle are recorded by a camera which is integrated in the mobile control unit. A visual signal is generated at a predetermined position on the vehicle, where remote control is only enabled if the visual signal is recorded by the camera. The device for the remote control of a function of a vehicle includes a mobile control unit with an integrated camera to record the images of the vehicle. A signal generation unit is arranged at a predetermined position on the vehicle for the generation of a visual signal and the vehicle includes a function unit for the control of the function. The function unit is formed in such a way that remote control is only enabled when the visual signal is recorded by the camera.
摘要:
For connecting a shaft to a rotating component, especially of a shaft to a turbine wheel of an exhaust gas turbocharger, an intermediate component is provided by means of which the shaft is connected indirectly to the rotating component. The connection between the rotating component and the intermediate component is a form-locking and/or force-locking connection, especially a riveted connection. The invention further relates to a method for producing said connection.

A side impact protection device with a pelvic airbag module having a pelvic airbag which, in the inoperative state, is in a side part of a vehicle seat and, in the event of an impact of the vehicle, can be inflated and can be deployed through an outlet opening in the side part of the vehicle seat. In order to provide a side impact protection device constructed in a simple manner and produced cost-effectively, the outlet opening for the pelvic airbag in the side part of the vehicle seat is directed upward and forward with respect to the direction of travel of the vehicle.
摘要:
A column tube switch module is radially and axially fixed to a column tube and is supported at the same time on a bearing arranged on the steering spindle. A centering device secures a stator radially to the column tube when a force is acting coaxially on the longitudinal axis of the steering spindle. A steering angle sensor is provided whose fixed part is connected to the stator-end bearing while its rotating part is held so as to be capable of being driven by the steering wheel hub.
