摘要： Deterioration of a selective catalytic reduction (SCR) catalyst (5) can be diagnosed with sufficient accuracy, by making use of a sensor (7) for measuring an air fuel ratio of exhaust gas flowing into an exhaust gas purification apparatus, which is equipped with the SCR catalyst (5), and a further sensor (8) for measuring an air fuel ratio of exhaust gas flowing out from the exhaust gas purification apparatus. In an exhaust gas purification apparatus for the exhaust gas purification apparatus, in a time period in which inducement-processing is carried out which is to induce a water gas shift reaction in a catalyst disposed at the upstream side of the SCR catalyst (5), by changing an air fuel ratio of exhaust gas discharged from an internal combustion engine (1) from a lean air fuel ratio into a predetermined rich air fuel ratio, an air fuel ratio of exhaust gas flowing into the SCR catalyst (5) and an air fuel ratio of exhaust gas flowing out from the SCR catalyst (5) are measured by said air fuel ratio sensors (7, 8), respectively, and deterioration of the SCR catalyst (5) is diagnosed based on a difference between the measured values of these sensors, wherein the inducement-processing is carried out when the amount of NH 3 adsorption in the SCR catalyst (5) is equal to or less than a predetermined amount.

摘要： An internal combustion engine is equipped with an exhaust purification catalyst (20), an upstream air-fuel ratio sensor (40), a downstream air-fuel ratio sensor (41), and sensor heaters (56) of the upstream air-fuel ratio sensor (40) and the downstream air-fuel ratio sensor (41). A control device comprises an air-fuel ratio control part configured to control the air-fuel ratio of the exhaust gas and a heating control part configured to control the heating of the air-fuel ratio sensors. The heating control part controls the sensor heaters so that the temperature of the upstream air-fuel ratio sensor (40) becomes less than the activation temperature and so that the temperature of the downstream air-fuel ratio sensor (41) becomes the activation temperature or more while the internal combustion engine is stopped by the automatic stop function. The air-fuel ratio control part controls the exhaust air-fuel ratio based on the outputs of the two air-fuel ratio sensors during engine operation and control the air-fuel ratio temporarily based on only the output of the downstream air-fuel ratio sensor (41) after the internal combustion engine has been restarted after automatic stop.

摘要： This invention relates to an air-fuel ratio control device of an internal combustion engine, and an object of the invention is to provide an air-fuel ratio control device of an internal combustion engine that is capable of suppressing a deterioration in the controllability of air-fuel ratio feedback control after restarting an engine. Figure 6 illustrates an elapsed time after engine startup, and output values of a front A/F sensor 16 and a rear A/F sensor 18. As shown in Figure 6 , the output values of the front A/F sensor 16 and rear A/F sensor 18 become equal from a time T3 onwards. Hence, by switching to normal air-fuel ratio feedback control at the time T3, highly accurate air-fuel ratio feedback control that is in accordance with the actual situation is enabled.

摘要： An apparatus includes an engine output module that determines an engine output power parameter for an engine. The apparatus includes an output power threshold module that determines if the engine output power parameter is below an output power threshold. The apparatus includes a NOx module that determines a nitrogen oxide (“NOx”) efficiency of a selective catalytic reduction (“SCR”) system in response to the output power threshold module determining that the determined engine output power parameter is below the output power threshold. The SCR system is in exhaust receiving communication with the engine. The apparatus includes a NOx threshold module that determines if the NOx efficiency is below a NOx efficiency threshold, and a NOx warning module that sends a NOx alarm signal in response to the NOx threshold module determining that the NOx efficiency is below the NOx efficiency threshold.
