Abstract: The invention concerns a method and a device for testing the function capacity of an NO oxidation catalyst (5) which is used to reduce nitrous oxides (NOx) contained in the exhaust gas flow of an internal combustion engine (1) operated with air surplus. In the exhaust gas flow which is supplied to the NO oxidation catalyst (5), a change is made in the concentration of a reducing agent and the resulting change in NOx concentration in the exhaust gas flow within the NO oxidation catalyst (5) and/or downstream after the NO oxidation catalyst (5) is determined and used to test its function capacity.

Abstract: A method and a device for operating a sensor is provided in an exhaust gas system of an internal combustion engine for determining the emissions contained in an exhaust gas flow, in particular, of nitrogen oxides, ammonia, oxygen and/or unburnt carbon, with the exhaust gas flow acting on the sensor during measurement phases. Between the measurement phases, the sensor is at least largely kept free from the exhaust gas flow, wherein the duration and/or the frequency of the measurement phases can be set as a function of operating parameters of the internal combustion engine and/or of the exhaust gas regulation system. A measurement space which surrounds the sensor is exposed to a pressurized flushing gas immediately after a measurement phase, as a result of which the exhaust gas present in the measurement space is displaced out of the measurement space into the exhaust gas flow.

Abstract: A method for use with an exhaust gas post-treatment system on an internal combustion engine operated with air surplus includes reducing nitrous oxides in that an ammonia-separating reducing agent is added to the exhaust gas flow upstream of a catalyst which is charged with a catalyst material for selective catalytic reduction of nitrous oxides. The method further provides that the NH3 to NOx ratio (feed ratio ?) is varied in phases by changing the untreated nitrous oxide emissions of the internal combustion engine such that the feed ratio ? oscillates in phases about a predefined value.

Abstract: Provides methods, systems and apparatus for coupling a general purpose processor (GPP) to an application specific instruction set processor (ASIP) in such a manner that the GPP can include execute instructions that do not normally comprise part of its instruction set architecture (ISA). The GPP is coupled to the ASIP via a coprocessor port such that instructions issued by the GPP to the port are conveyed to a novel pre-decoder module of the ASIP. The pre-decoder module translates the GPP instruction into operation codes for ASIP instructions to be executed in the ASIP or to an address in the ASIP instruction memory that identifies a start address for a plurality of ASIP instructions defining a complex application specific function. Once the ASIP has executed the instructions it shares the result of the execution with the GPP. In this way, the GPP takes advantage of the ASIP in its ability to more quickly execute an application specific program/procedure.

Abstract: Provides methods, systems and apparatus for timer management of an element processing system wherein timer intervals related to elements to be processed can be handled in a time-efficient manner. An example method is a method for detecting a timeout of elements in an element processing system wherein a timer value, indicating a timeout interval with respect to a given time base, is assigned to each of the elements when processed. From a number of elements processed, the timer value indicating a minimum timeout interval to expire is determined out of the number of timer values assigned to the number of elements being processed.
