Abstract: An apparatus for determining the homogeneity of a fluid flow in a pipe, such as a reducing-agent flow in an exhaust-gas pipe of an internal combustion engine, including a transmitter arranged on a light-transmissive region of the pipe and a diametrically opposite detector. The transmitter and detector being coupled such that they are rotatable through an angle of 360° about a rotational axis which is located substantially in the axis of symmetry of the pipe. The transmitter and the detector are rotated through at least 360° about the rotational axis, thus capturing an intensity of the detected light over the rotation angle, and from this a homogeneity of the fluid flow is deduced.

Abstract: Proposed is a method for assessing the completeness of a regeneration of a particle filter which is traversed by the exhaust gas of an internal combustion engine, wherein a pressure difference which is generated across the particle filter when a flow passes through the particle filter is measured and evaluated for the assessment. The method is characterized in that a time derivative of the measured pressure difference is formed and the assessment of the completeness of the regeneration takes place as a function of the time derivative.

Abstract: A method of controlling a reducing agent generation system of an internal combustion engine includes generating a reagent substance in a form of pulses and delivered to an exhaust gas duct of the internal combustion engine upstream of an SCR-catalytic converter for the selective catalytic reduction of the nitrogen oxides contained in an exhaust gas. A catalytic converter model is used to model a reagent substance fill level of the SCR-catalytic converter and a closed-loop feedback control system compares the modeled reagent substance fill level with a storage set point. A reagent substance demand signal is generated that at least releases a reagent substance pulse when a difference between the storage set point and the reagent substance fill level exceeds a specified threshold value.

Abstract: Properties of real nodes are selected by which to organize the real nodes as leaf nodes in a tree graph. A number of virtual nodes are provided, each representing a value of a selected property for at least one of the real nodes. The virtual nodes and real nodes are organized into the tree graph, the virtual nodes positioned along branches starting at a root node and ending at a real node, the virtual nodes in a unique path from the root node to a real node representing the values of the selected properties for the real node. The tree graph is displayed, and can be reconfigured by dragging and dropping a virtual node to a different level in the hierarchy of the tree graph.

Abstract: Methods and apparatus including computer program products implement techniques for developing and deploying applications using configurable patterns. Configuration data is received for a pattern, and the configuration data is stored in a design store. The pattern defines an arrangement of user interface elements and specifies predefined actions that can be performed using the user interface elements. The configuration data specifies associations between one or more of the user interface elements or one or more objects in a back-end system. The configuration data is transferred from the design store to a design time repository, and the application is deployed corresponding to the configuration data.

Abstract: The invention relates to a direct-injection internal combustion engine that is operated in a first operating range associated with the low part load, with largely homogeneous combustion of the mixture and subsequent injection. Said internal combustion engine is operated in a second operating range associated with the middle part load, with low-temperature combustion of the mixture. In this way, minimum nitrogen oxide and soot emissions and a high degree of efficiency can be achieved both in the lower part load region and up to the full load region.

Abstract: Methods and apparatus, including computer program products, for a single keystroke file comparison tool. A first version of a file is downloaded from a repository to a client computer. An updated version of the file is downloaded from the repository to the client computer. State information for the file is stored. The state information specifies two versions of the file. In response to a single user input, a file comparison is performed on the file. The file comparison produces an output showing differences between the two versions specified by the state information for the file. The state information can be stored in a hyperlink that refers to the file. User input selecting the hyperlink invokes the file comparison on the file.

Abstract: A method for operating a direct injection diesel engine which is operated in a first operating region corresponding to low to medium partial load in such a way that fuel combustion takes place at a local temperature below the temperature of NOx formation and with a local air ratio above the limit value for soot formation, and where fuel injection starts in a range of between 50° to 5° crank angle before top dead center of the compression phase and where exhaust gas is recirculated at an exhaust gas recirculation rate of 50% to 70%. In order to achieve high efficiency in each operating region while keeping NOx and particulate emissions low, in a second operating region corresponding to medium partial load, fuel injection is started in a range from approximately 2° crank angle before top dead center to approximately 20° crank angle after top dead center.
