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： 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。

摘要： An exhaust gas purifying apparatus is provided which includes a three way catalyst provided in an exhaust pipe of an internal combustion engine; and a NOx adsorption/reduction catalyst provided in the exhaust pipe to be located downstream of the three way catalyst. Nickel serving as a catalyst source is loaded on an alumina support layer of the NOx adsorption/reduction catalyst. When the engine operates with a fuel-rich air/fuel mixture at a relatively small air-fuel ratio, a reducing atmosphere is formed around the NOx catalyst, and the reaction to convert NiO into NiS occurs, thereby to consume H2S. As a result, consumption of SO2 proceeds, and the reaction to convert BaSO4 as an oxidized product of sulfur deposited on the NOx catalyst into BaCO3 as an NOx adsorbent is accelerated in an oxidizing atmosphere, thereby resuming the purifying capability of the NOx catalyst.

摘要： Flammable fine particles (particulates) consisting principally of carbon and hydrocarbons are discharged from a diesel engine to its exhaust system. A diesel particulate oxidizer (DPO) is disposed in the exhaust passage for collecting and burning the particulates without allowing the particulates to be discharged directly to the atmosphere. This DPO comprises a ceramic foam with catalyst. When the quantity of particulates collected is above a predetermined value, the DPO will undergo clogging. To prevent this, a high temperature gas containing oxygen is fed to the DPO to burn (regenerate) the collected particulates. In order to accelerate the normal regeneration of the DPO, there are provided a regeneration means for making a retard control of the fuel injection timing in the diesel engine, and a regeneration timing control means for controlling the operation of the regeneration means. Further, there is provided a regeneration timing detection means for detecting the regeneration timing of the DPO.
