摘要： An exhaust gas purification device for an internal combustion engine comprises, an exhaust passage including a catalyst for conveying exhaust gas discharged from the engine to the outside, and a bend formed by bending a portion of the exhaust passage directly upstream of the catalyst, the bend causing exhaust gas discharged from the engine to collide against a corner portion between an inlet end face of the catalyst and such portion of a wall of the exhaust passage that follows the outside of the bend, thereby increasing pressure at the corner portion, compared with the other portion of the inlet end face, and an additive injection valve fitted to the outside of the bend of the exhaust passage to inject an additive in such manner that the injected additive passes just above the corner portion and falls on the inlet end face of the catalytic converter.

摘要： An apparatus for controlling an internal combustion engine having an exhaust purifying catalytic device which absorbs nitrogen oxides contained in exhaust when the engine is in a lean-combustion mode and which deoxidizes the absorbed nitrogen oxides when the engine is in a rich-combustion mode. The engine control apparatus includes an electronic control unit for estimating the amount of purifying capability reducing substances other than nitrogen oxides, which decreases the nitrogen oxide adsorbing ability of the catalytic device, absorbed by the catalytic device, on the basis of the accumulated value of vehicle travel distance, fuel consumption of engine, or intake air amount. The control unit changes the operating condition of engine so that the exhaust gas temperature is increased when it is judged that the estimated adsorption amount has reached a predetermined adsorption amount. The exhaust purifying catalytic device is heated by high-temperature exhaust gas to remove the purifying capability reducing substances from the catalytic device.

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 exhaust purifying apparatus for an in-cylinder injection type internal combustion engine causes exhaust gas temperature to rise reliably, thereby desorbing reliably a sulfur component (SOx) adhered to an NOx catalyst and enhancing the durability of the NOx catalyst. For this reason, the exhaust purifying apparatus for an in-cylinder injection type internal combustion engine comprises an NOx catalyst (9A) for adhering NOx to itself in an excess oxygen concentration condition and desorbing NOx in an oxygen concentration reduction condition, and sulfur component desorption means (107) for desorbing a sulfur component from the NOx catalyst (9A). The sulfur component desorption means (107) injects additional fuel during an expansion stroke in addition to main injection and burns the additional fuel again so that exhaust gas temperature is raised to a predetermined temperature or beyond, whereby the sulfur component is desorbed.

摘要： In a control apparatus and control method for an internal combustion engine having an exhaust purifying catalytic device for adsorbing nitrogen oxide contained in exhaust gases from the engine, the adsorption state of nitrogen oxide adsorbed by the catalytic device is estimated by an electronic control unit during the lean-combustion driving of the engine. If the catalytic device is saturated with nitrogen oxide, the ignition timing is delayed and the exhaust gas is recirculated to the intake side of the engine with the lean air-fuel ratio kept unchanged. This starts the nitrogen oxide reduced driving mode for deteriorating the combustion state in the engine. At this time, the engine output will not change by a great amount. Further, a reducing atmosphere is created around the catalytic device by unburnt gases, generated due to the deterioration of the combustion state, to deoxidize the adsorbed nitrogen oxide. As a result, the purifying ability of the catalytic device can be recovered to suppress the discharge amount of nitrogen oxide without deteriorating the smoothness of engine driving and fuel economy.
摘要翻译：在具有用于吸附来自发动机的废气中含有的氮氧化物的排气净化催化装置的内燃机的控制装置和控制方法中，催化装置吸附的氮氧化物的吸附状态由电子控制装置在发动机的稀燃驱动。如果催化装置被氮氧化物饱和，则随着空燃比保持不变，点火正时延迟并且排气再循环到发动机的进气侧。这就开始了用于使发动机的燃烧状态恶化的氮氧化物还原驱动模式。此时，发动机输出不会发生大的变化。此外，由于燃烧状态的劣化而产生的未燃烧气体在催化装置周围产生还原气氛，以使吸附的氮氧化物脱氧。结果，可以回收催化装置的净化能力，以抑制氮氧化物的排放量，而不会降低发动机驱动的平滑性和燃料经济性。
