摘要： An improved monitoring of a measurement chain with a sensor is achieved by using a broadband test signal. Thereby, the entire frequency range of a sensor can be covered with one test signal. There is no need to switch between different test signals and the available time for a diagnostic run can be used optimally. The broadband test signal allows better separation of the test signal and the useful signal. The integrity of an AC current measurement is increased by this approach. This can simplify the monitoring of a DC current sensor or even eliminate the need for an additional DC current sensor. In both cases, cost savings can be achieved.

摘要： A propagation test cell includes a first substantially cuboid housing part and a drive mechanism arranged therein. The drive mechanism moves a nail along a movement axis. A second housing part has a reference surface parallel and directed opposite to a reference surface of the first housing part and is in contact therewith. The second housing part has a passage coaxial with the movement axis of the nail. The passage has a passage cross-sectional area greater than the diameter of the shank of the nail. Dimensions of the outer form of the propagation test cell correspond to a multiple of the respective dimensions of a battery cell with which the propagation test cell can be arranged within a cell module, so that the propagation test cell can be substituted with at least one additional battery cell or with a multiple thereof within a cell module.

摘要： A method for operating an internal combustion engine having a combustion method with homogeneous auto ignition. A driver's demand, predetermined by the gas pedal, is converted into a desired torque to be given off by the engine. A reference charge value for the air charge is determined by a working-point-dependent lambda value (λopt) that can be predetermined. Based on this, a throttle valve position is set. Parallel to this, a desired torque is calculated for the fuel path with a reference lambda value, and an actual charge is calculated to yield a fuel amount to be injected. The reference lambda value results from an optimal lambda value for the mode of operation of homogeneous compression ignition, as long as the lambda value is within the rich and lean limits, respectively, of the combustion method of homogeneous compression ignition. The fuel mass is varied within the rich and lean limits to compensate dynamic processes.

摘要： A reciprocating-piston internal combustion engine has a crank drive and a transmission lever indirectly coupled with the piston and intersecting the cylinder axis. The lever is articulated onto the crank drive's connecting rod and onto an adjustable bearing guided in the cylinder block. For greater variation of the translation of movements between crank drive and piston, the pulling and pushing rod connected with the piston has a guide at its end facing the transmission lever. The guide is preferably a pivotally-mounted slide shoe that engages into a guide extending along the transmission lever. The transmission lever is pivotally connected with the crankshaft connecting rod and connected with a setting drive for variably setting the articulation of the pulling and pushing rod on the transmission lever. A guide lever pivotally connected with the pulling and pushing rod and pivotally articulated onto the cylinder block guides the pulling and pushing rod.

摘要： An exhaust-gas turbocharger includes: an exhaust-gas turbocharger housing having a turbine housing, a compressor housing, and a bearing housing; a turbine in the turbine housing; a compressor in the compressor housing; and a shaft rotatably mounted in the bearing housing by which the turbine and the compressor are rigidly connected, at least one channel having an inlet opening and an outlet opening being formed inside the shaft, the inlet opening and/or the outlet opening being arranged in a radial direction on a circumference of the shaft between the turbine and the compressor. The at least one channel is part of a channel system of an exhaust-gas recirculation system, a reducing agent infeed, or a secondary air infeed. For the secondary air infeed, an interior space of the compressor housing is in fluidic connection with an interior space of the turbine housing.
