摘要： In an internal combustion engine, an SO x trap catalyst (13) which traps SO x contained in the exhaust gas is arranged upstream of an NO x storing catalyst (15) in an engine exhaust passage. When the NO x storing catalyst (15) should release NO x , auxiliary fuel is injected into a combustion chamber (2) at a combustible timing after the completion of injection of fuel into the combustion chamber (2) for generating the engine output. At this time, the auxiliary fuel is injected so that the air-fuel ratio A/F of the combustion gas in the combustion chamber (2) does not become below a minimum allowable air-fuel ratio M where SO x trapped at the SO x trap catalyst (13) will not be released.

摘要： An internal combustion engine in which an SO x trap catalyst (11) able to trap SO x contained in exhaust gas is arranged in an engine exhaust passage upstream of an NO x storing catalyst (12). The SO x trap catalyst (11) is strengthened in basicity compared with the NO x storing catalyst (12) to an extent so that when the temperature of the SO x trap catalyst (11) is in the temperature range at the time of ordinary operation, that is, substantially 150°C to substantially 400°C, the NO x purification rate by the SO x trap catalyst (11) becomes less than substantially 10 percent of the NO x purification rate by the NO x storing catalyst (12). When NO x should be released from the NO x storing catalyst (12), the air-fuel ratio of the exhaust gas flowing into the SO x trap catalyst (11) is temporarily switched from lean to rich.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning apparatus for internal combustion engine for reducing a difference of the torque between a lean-burn mode and a rich-burn mode.
SOLUTION: During the shifting from a lean-burn mode to a rich-burn mode, the weight of oxygen inside a cylinder is computed (S20), an excess air ratio is computed by using the weight of oxygen inside the cylinder (S30), and a rate of combustion is computed (S40). In the final fuel injection during the lean period, a torque value corresponding to the burning quantity of fuel is computed, and the obtained value is used as a target torque correspondent value in the rich period (S60). In the case wherein the excess air ratio is not less than 1, probability of danger in a torque shock is determined large, and the injection quantity for achieving a torque correspondent value the same as that of the lean period is computed based on the rate of combustion obtained in S40 and the injection quantity obtained in S60 (S80). In the case wherein the excess air ratio is less than 1, probability of danger in a torque shock is determined small, and the injection quantity is set at a preset rich-time target injection quantity (S90).

摘要： PROBLEM TO BE SOLVED: To determine whether an NOx clean-up rate is lowered due to the degradation of an NOx selective reduction catalyst or due to the abnormality of urea water. SOLUTION: When the NOx selective reduction catalyst 15 is degraded, the clean-up rate NR is increased according to the rise of a catalyst temperature TC as shown by a curve B1. When the supply amount or quality of the urea water is abnormal, the NOx clean-up rate NR is uniformly lowered as shown by a curve C. When the NOx clean-up rate NR comes within an area X 2 and also comes within an area Y 1 , the degradation of the catalyst occurs. When the clean-up rate comes within an area Y 2 , the supply amount or quality of the urea water is considered to be abnormal. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To preferably and simply detect abnormality in a urea addition system in a urea SCR system. SOLUTION: In an exhaust gas purification sytem in which an aqueous urea solution is added to a NOx selective reduction catalyst placed in an exhaust gas passage in an internal combustion engine by means of a urea addition device, a sensor for detecting the concentration of ammonia is arranged on the downstream side of the NOx catalyst. The addition of a predetermined amount of the aqueous urea solution is carried out during a fuel cut. Based on the output from the senser at this point, the abnormality in at least one of the urea addition device and the aqueous urea solution is detected. By adding the aqueous urea solution during the fuel cut, it becomes possible to prevent the reactive consumption between urea and NOx, and it becomes also possible to produce an output corresponding to the amount of the aqueous urea solution from the sensor. By comparing the output state with a normal one, it can be detected whether or not a proper amount of an aqueous urea solution having proper quality is added. COPYRIGHT: (C)2009,JPO&INPIT
