摘要： An engine includes an exhaust gas system which flows exhaust gasses through an aftertreatment device. A method is provided for detecting the aftertreatment device during a transient operating condition. The method includes sensing temperature of the exhaust gas at an inlet and at an outlet of exhaust aftertreatment system. The inlet temperature is filtered and an inlet temperature difference between the filtered and unfiltered inlet temperatures is calculated. If the absolute value of the inlet temperature difference is greater than the predetermined threshold, then an outlet temperature difference is calculated. If the absolute value of the outlet temperature difference is greater than the second threshold, then a fault signal is generated, indicating that an aftertreatment device is missing. The aftertreatment device includes an SCR catalyst and an ammonia oxidation catalyst.

摘要： The invention relates to a method, in an SCR system in which reducing agent is supplied to an exhaust flow upstream of an SCR catalyst (260), for deciding whether a NOx sensor (245; 255) is situated in the exhaust duct (241; 251 ) of an engine (240) for NOx measurement according to an intended measuring configuration. The method comprises the steps of using said NOx sensor (245; 255) to measure an oxygen content (Oxmeas) at the NOx sensor's measuring position, and deciding on the basis of the measured oxygen content (Oxmeas) whether said measuring position corresponds to the intended measuring configuration. The invention relates also to a computer programme product comprising programme code (P) for a computer (200; 210; 500) for implementing a method according to the invention. The invention relates also to an SCR system and a motor vehicle (100, 110) which is equipped with the SCR system.

摘要： A system to detect the presence of a catalyst includes an exhaust gas tube, a first temperature sensing device, a second temperature sensing device, a flow rate measurement device, and a processing device. The first temperature sensing device measures a first temperature of exhaust gas upstream of the exhaust gas tube. The second temperature sensing device measures a second temperature of the exhaust gas downstream of the exhaust gas tube. The processing device estimates an expected time delay between the measured inlet and outlet exhaust gas temperatures corresponding to a system with a catalyst present. The processing device may also determine the presence of a catalyst by comparing the measured second temperature to the measured first temperature and comparing the measured second temperature to an estimated delayed first temperature associated with the expected time delay.

摘要： A system for and method of diagnosing operation of a partial filtration filter exhaust aftertreatment system are provided. An upstream exhaust temperature value is determined in an exhaust system upstream of at least one of a diesel oxidation catalyst (DOC) component and a first partial flow filter (PFF) component. A downstream exhaust temperature value is determined in the exhaust system downstream of a second PFF component positioned downstream of the at least one of the DOC component and the first PFF component. A frequency difference is determined between a first frequency content of the upstream exhaust temperature value and a second frequency content of the downstream exhaust temperature value. If the frequency is less than a predetermined threshold, it is determined that at least one of the DOC component and the PFF component are not present in the exhaust system.

摘要： In a control apparatus for an internal combustion engine in which an SCR catalyst is arranged in an exhaust passage, a dummy determination processing to determine whether the selective catalytic reduction catalyst is mounted at a location is carried out, based on a temperature difference between a temperature of exhaust gas flowing into the location where the selective catalytic reduction catalyst is to be arranged and a temperature of exhaust gas flowing out of the location, after starting of the internal combustion engine, wherein when a period of time for the temperature of the selective catalytic reduction catalyst to become equal to or less than a fixed temperature is equal to or more than a predetermined period of time, the dummy determination processing is carried out, whereas when the period of time is less than the predetermined period of time, the dummy determination processing is not carried out.
