摘要： A controller for an internal combustion engine is configured to execute a determination process that determines that a deviation between a first change amount and a second change amount during a fuel cutoff operation is less than or equal to a threshold, and an anomaly diagnosing process that determines that an exhaust purification device is in a detached state when the determination process determines that the deviation is less than or equal to the threshold. The first change amount and the second change amount are change amounts per unit time of the temperature of exhaust gas on the upstream side and the downstream side of the exhaust purification device, respectively. The controller is configured to interrupt the determination process when the upstream-side temperature increases within a determination period.

摘要： Provided is an exhaust gas purification apparatus having a control device that monitors the transition of a detection value of each of an upstream NOx sensor and a downstream NOx sensor, and when the NOx purification rate of the SCR catalyst falls to a value of a first threshold or lower, generates an abnormality detection signal indicating that an over storage state has occurred in an SCR catalyst if the amount of change in the detection value of the upstream NOx sensor per unit time is at least a second threshold and the amount of change in the detection value of the downstream NOx sensor per unit time is at most a third threshold.

摘要： A method of ageing a catalyst material includes at least the steps of: (a) heating a gaseous stream; (b) adding a least one pure hydrocarbon gas and an oxygen-containing gas to the heated gaseous stream to provide a combined stream; and (c) passing the combined stream through the catalyst material. The use of at least one pure hydrocarbon gas and an oxygen-containing gas allows maximum re-circulation of the exit stream from the catalyst material for reuse, while maintaining the correct C, H and O proportions being provided in the combined stream to replicate realistic use of the catalyst material.

摘要： A temperature control system and method for use with an exhaust flow simulation system. A typical exhaust flow simulator is a burner-based system, in which exhaust from a combustive burner is exhausted through an exhaust line. A temperature control section divides the exhaust from the burner line into two paths: a cool path and an uncooled (hot) path. The cool path uses a heat exchanger to cool the exhaust. The cool path also has a control valve that controls the relative portions of hot and cool exhaust, which are re-mixed downstream the valve into an exhaust line. Various embodiments have different configurations for the two paths.

摘要： A method for modifying a NOx adsorber regeneration triggering variable. Engine operating conditions are monitored until the regeneration triggering variable is met. The adsorber is regenerated and the adsorbtion efficiency of the adsorber is subsequently determined. The regeneration triggering variable is modified to correspond with the decline in adsorber efficiency. The adsorber efficiency may be determined using an empirically predetermined set of values or by using a pair of oxygen sensors to determine the oxygen response delay across the sensors.
