摘要： A method for operating a catalytic converter used for purifying the exhaust gas of an internal combustion engine, and a device for implementing the method, which provide for an open-loop or closed-loop control of the reagent fill level in the catalytic converter to a predefined storage setpoint value. The targeted stipulation of the storage setpoint value ensures, on one hand, that in non-stationary states of the internal combustion engine, there is a sufficient quantity of reagent available for the completest possible removal of at least one unwanted exhaust-gas component, and on the other hand, a reagent slip is avoided.

摘要： A method for operating an internal combustion engine whose exhaust area has at least one SCR catalytic converter and a device for carrying out the method are described. The SCR catalytic converter receiving the reagent supports the conversion of the raw NOx emission of the internal combustion engine. At least a measure of the NOx concentration occurring downstream from the SCR catalytic converter is calculated and this value may be used to define a metering signal for the reagent and/or a heating measure for heating the SCR catalytic converter may be initiated. According to a refinement of this arrangement, a difference between the calculated NOx concentration and the sum of the measured NOx concentration and the measured reagent concentration downstream from the SCR catalytic converter is determined, and it is possible to intervene in the determination of the metering signal depending on the difference.

摘要： The invention concerns a procedure to monitor an exhaust gas after-treatment system of an internal combustion engine with a motor block and an exhaust gas duct, which has at least one catalytic converter, upstream from which a reagent substance necessary for the NOx reduction in the catalytic converter is introduced by means of an introduction device, whereby the reduction agent rate is increased to such an extent at defined reference operating points until an ammonia breach is detected in direction of flow behind the catalytic converter by means of an ammonia sensitive sensor in the exhaust gas duct.The invention additionally concerns a device to monitor an exhaust gas after-treatment system of an internal combustion engine with a motor block and at least one exhaust gas duct, which has at least one NOx sensor to determine the NOx content in the exhaust gas and at least one catalytic converter, upstream from which a reagent substance necessary for the NOx reduction in the catalytic converter can be introduced by means of an introduction device, whereby the NOx sensor as well as additional sensors to measure the temperature at the catalytic converter and to measure the air in the air delivery duct as well as an ammonia sensitive sensor in the direction of flow behind the catalytic converter maintain an active connection to the monitoring unit, whereby an excess metering of the reagent substance can be intentionally initiated in the monitoring unit, an ammonia breach can be detected by means of an ammonia sensitive sensor and the ammonia storage capability can be determined.The optimized metering strategy, which is thereby guaranteed, allows for high NOx conversions with minimal ammonia slip, which is especially advantageous with regard to the stricter exhaust gas standards.

摘要： A procedure to operate a particle filter disposed in an exhaust gas area of an internal combustion engine and a device to implement the procedure are proposed. The particle filter is regenerated if required by the particles lodged in the filter, whereby the particle filter is heated for regeneration by manipulation of the exhaust gas temperature upstream in front of the particle filter. During the regeneration of the particle filter, the exhaust gas temperature is established to a specified exhaust gas temperature set point, which is dependent upon at least one parameter of the particle filter during the regeneration. The procedural approach according to the invention allows for a quick regeneration of the particle filter without endangering the particle filter with an inadmissibly high temperature.
