摘要： When NOx-releasing means is operated to change an air-fuel ratio to a rich side to thereby establish a low-oxygen-concentration atmosphere of exhaust such that NOx is released from an NOx catalyst, reducer-supplying means 33 additionally supplies a reducer during an operating period of the NOx-releasing means for reducing NOx released into an exhaust path such that release of NOx balances with reduction of NOx, thereby reducing NOx released from the NOx catalyst and thus suppressing worsening of exhaust gas performance.

摘要： The present plasma type exhaust gas cleaning apparatus comprises a dielectric (5) arranged between a discharge electrode (7) and a ground electrode (8). The dielectric has a plurality of independent cavities (6) formed therein. The exhaust gas from combustion equipment (1) flows through the interiors of the plurality of independent cavities (6). Thus, in the plasma type exhaust gas cleaning apparatus, the discharge electrode (7) and the ground electrode (8) are securely partitioned by the cavities (6). When a voltage from a high voltage generator (9) is applied to between the discharge electrode (7) and the ground electrode (8), plasma resulting from corona discharges occurs in each individual cavity (6) without arising directly across the discharge electrode (7) and the ground electrode (8). The exhaust gas is thereby cleaned up.

摘要： AN APPARATUS FOR CONTROLLING AN IGNITION OF A CYLINDER-INJECTION GASOLINE ENGINE (1) INCLUDES AN ELECTRONIC CONTROL UNIT (ECU) FOR CONTROLLING THE OPERATION OF AN IGNITION COIL. THE ECU ADVANCES THE IGNITION TIMING IN ACCORDANCE WITH THE THROTTLE OPENING (qTH) IN CONSIDERATION OF A DELAY IN INCREASE OF THE WALL TEMPERATURE (TCW) OF A COMBUSTION CHAMBER (5) WHEN THE ACCELERATION OF A VEHICLE IS DETECTED BY THE CHANGE OF THE THROTTLE OPENING (qTH). IN ORDER TO PREVENT KNOCKING OF THE ENGINE (1) ATTRIBUTABLE TO THE INCREASE OF THE WALL TEMPERATURE (TCW), THE ECU GRADUALLY DECREASES AN ADVANCE ANGLE FOR THE IGNITION TIMING TO 0 WITH THE PASSAGE OF CONTROL TIME. WHEN THE ENGINE (1) IS REACCELERATED DURING THE ADVANCE ANGLE CORRECTION, THE ECU NEWLY SETS AN ADVANCE ANGLE FOR THE IGNITION TIMING AND A CONTROL TIME, CORRESPONDING TO THE INCREASE OF THE WALL TEMPERATURE (TCW).

摘要： It is an object of the present invention to provide an exhaust gas purifying catalyst formed as a single catalyst that has a lot of freedom when being assembled into an exhaust system and that is capable of executing both an NOx absorbing function and a three-way function in a refined manner. To attain the this object, an absorbent catalyst layer to which an absorbent agent such as potassium and an acid material such as zeolite are added, an absorbent agent block layer formed of zeolite, and a three-way catalyst layer to which an acid material such as phosphorus is added are bonded together on a cordierite carrier. The acid material in the absorbent catalyst layer and the absorbent agent block layer inhibit the movement of the absorbent agent to the three-way catalyst layer, and transform the absorbent agent into harmless and stable potassium phosphate even if the absorbent agent reaches the three-way catalyst.

摘要： A catalytic apparatus for exhaust purification, provided in an exhaust path of an internal-combustion engine operable with at least a theoretical air-fuel ratio and a lean air-fuel ratio, is provided with a three-way catalyst (4) having an inner layer (12a) thereof mainly containing rhodium as a noble metal to be activated in an oxygen concentration lowering atmosphere and a surface layer (12b) thereof mainly containing platinum or palladium as a noble metal to be activated in an oxygen concentration increasing atmosphere. In the catalytic apparatus, platinum or palladium in the surface layer is activated in lean operation to perform an HC purifying function effectively. If oxygen is temporarily in short supply during the change from a lean air-fuel ratio of exhaust gas over to a stoichiometric air-fuel ratio, oxygen is supplemented to purify HC by utilizing the O2 storage function of platinum or palladium as the noble metal, whereby the HC purifying rate can be prevented from temporarily suddenly lowering. The catalytic apparatus for exhaust purification can secure satisfactory HC purifying performance even in a lean area without increasing the noble metal loading of the three-way catalyst, so that it can be manufactured at low cost.

摘要： An exhaust emission control device of an internal combustion engine (1), which purifies exhaust gas exhausted from the internal combustion engine (1), comprises: a catalyst device (13) composed of a three way catalyst (32,34) for purifying harmful substance in the exhaust gas when an exhaust air-fuel ratio is substantially stoichiometrical and an NOx catalyst (33) having a function of absorbing NOx in the exhaust gas when the air-fuel ratio is closer to a lean air-fuel ratio than to the stoichiometrical air-fuel ratio, the catalyst device (13) being provided in an exhaust passage (11) of the internal combustion engine (1); catalyst deterioration determination means (S1,S3,S15,S17) for determining deterioration state of the catalyst device (13), the deterioration resulting from at least temperature; and control means (31,S4,S16,S18) for deteriorating exhaust gas components flowing into the catalyst device (13) much more than exhaust gas components flowing into the catalyst device (13) when an air-fuel ratio of a mixture supplied to the internal combustion engine (1) is substantially stoichiometrical, if the catalyst deterioration determination means (S1,S3,S15,S17) determines that the catalyst device (13) is in a predetermined deterioration state. The deterioration of an NOx absorbing function of the NOx catalyst (33) results from at least the destabilization of absorbing material in the NOx catalyst (33), which is caused by the rise in the temperature. Thus, if the catalyst deterioration determination means (S1,S3,S15,S17) determines that the catalyst device (13) is in the predetermined deterioration state, the exhaust gas components flowing into the catalyst device (13) are deteriorated much more than the exhaust gas components flowing into the catalyst device (13) when the air-fuel ratio of the mixture supplied to the internal combustion engine (1) is substantially stoichiometrical. Therefore, CO, H2, NOx, O2, THC and the like are supplied to the absorbing material to thereby stabilize the absorbing material as carbonate, nitrite or acid oxide. This prevents the heat deterioration. This extends a heat-resisting life of the catalyst device (13), and prevents the deterioration of an exhaust gas characteristic and the increase in cost.
