摘要： A method of controlling an NOx purification system (1), the system provided with an NOx occlusion reduction catalyst (22) and a control unit (30) that conducts NOx regeneration control and sulfur poisoning regeneration control. In the control method, the degree of deterioration of the NOx occlusion reduction catalyst (22) due to sulfur poisoning is estimated on the basis of the amount of the oxygen adsorbed and occluded at the NOx occlusion reduction catalyst (22) immediately after terminating the rich air-fuel state of the NOx regeneration control. In so doing, the amount of sulfur poisoning in the NOx occlusion reduction catalyst (22) is accurately estimated, and by performing sulfur poisoning regeneration at a suitable frequency, excessive sulfur poisoning regeneration can be avoided, thereby preventing the worsening of fuel consumption.

摘要： An internal combustion engine wherein 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). When the air-fuel ratio of the exhaust gas flowing into the SO X trap catalyst (11) is switched from lean to rich to make the NO X storing catalyst (12) release the NO X , if the temperature of the SO X trap catalyst (11) is the SO X release lower limit temperature or more, rich processing making the air-fuel ratio of the exhaust gas flowing into the SO X trap catalyst (11) rich for making the NO X storing catalyst (12) release NO X is prohibited.

摘要： A method for estimating the sulfur content in the fuel of an internal combustion engine (1) equipped with a catalyser (11); the percentage (S) of sulfur present in the fuel supplied during a specific measurement time interval is estimated by dividing the quantity of sulfur (SOxstored) stored in the catalyser (11) during the measurement time interval by the product of a fixed conversion constant (KSOx) and the mass of fuel (mfuel) supplied to the cylinder (2) in the measurement time interval.

摘要： An exhaust gas cleaning system comprises sulfur oxide (SO x) occlusion amount estimation section (20a), exhaust air-fuel ratio control section (20b), sulfur oxide poisoning recovery section (20c) and hydrocarbon concentration detector (20d). When the sulfur oxide occluded in nitrogen oxide (NO x) catalyst (16) is released, the air-fuel ratio of exhaust gas flowing into catalyst is controlled at richer side with decreased amount of sulfur oxide occlusion. An independent claim is included for sulfur oxide poisoning recovery method.

摘要： The invention relates to a method for desulphurating at least one NOx-storage catalyst that is arranged in an exhaust channel of a combustion engine. A minimum desulphurating temperature is adjusted for the NOx-storage catalyst and a working mode of the combustion engine is adjusted with lambda ≤ 1 for desulphurisation. At least one operation parameter of the combustion engine is at least temporarily influenced in order to obtain said working mode and/or the minimum temperature. According to the invention, desulphurisation is initiated according to a current lambda value and/or a relation of the NOx-concentration upstream and downstream in relation to the NOx-storage catalyst (16) according to an NOx-mass (thionation degree) that is embedded in the NOx-storage catalyst and/or a current temperature of the NOx-storage catalyst (16).

摘要： An exhaust gas purifying apparatus comprises a control unit (29) operative to estimate an amount of NOx absorbed by a NOx trap material (17) disposed in an exhaust passage (10) and to make an air-fuel ratio richer so as thereby to cause the NOx trap material to release sulfur when the estimated amount of NOx absorption exceeds a specified amount. Further, the control unit (29) operative to estimate an amount of sulfur absorbed by the NOx trap material (17) and to make an air-fuel ratio richer and rising a temperature of exhaust gas so as thereby to cause the NOx trap material to release sulfur when the estimated amount of sulfur absorption exceeds a specified amount. The control means restricts an air-fuel ratio from being made richer when the NOx trap material is not expected to absorb NOx due to progress of sulfur absorption resulting from conditionally the sulfur releasing.
