摘要： An exhaust emission control system of an internal combustion engine desorbs SOx by reversing a flow of an exhaust gas through an NOx storage-reduction catalyst, of which a structure is simplified as follows. A first exhaust pipe connected to an engine is connected to a first port of an emission switching valve having four ports. A second exhaust pipe 10, through which the exhaust gas is discharged into the atmospheric air, is connected to a second port, a third exhaust pipe connected to an inlet of a catalytic converter is connected to a third port. A fourth exhaust pipe connected to an outlet of the catalytic converter 30 is connected to a fourth port. When the emission switching valve is set in a forward flow position, the first exhaust pipe is connected to the third exhaust pipe, and the second exhaust pipe is connected to the fourth exhaust pipe, whereby the exhaust gas flows toward the outlet from the inlet within the catalytic converter. When the emission switching valve is set in a backward flow position, the first exhaust pipe is connected to the fourth exhaust pipe, and the second exhaust pipe is connected to the third exhaust pipe, whereby the exhaust gas flows toward the inlet from the outlet within the catalytic converter.

摘要： In an exhaust gas purification device, a catalytic converter containing selective reduction catalysts is disposed in an exhaust gas passage of an internal combustion engine capable of being operated at a lean air-fuel ratio. The catalytic converter includes a plurality of the selective reduction catalysts disposed in series in the casing of the catalytic converter. Bypass passages which supply the exhaust gas to downstream selective reduction catalysts in the casing by bypassing the upstream catalysts are provided. When a reducing agent is supplied to the exhaust gas upstream of the converter, a part of the supplied reducing agent directly reaches the downstream selective reduction catalyst through the bypass passages without being oxidized by the upstream selective reduction catalysts. Therefore, the NOx purifying abilities of the downstream catalysts are improved and the formation of sulfates on the downstream catalysts is suppressed.

摘要： In an exhaust gas purification device, an exhaust gas passage of a diesel engine diverges into two branch pipes and a particulate filter (DPF) is disposed in each of the branch pipes. The DPF uses a metallic substrate and NO.sub.x absorbent is attached to the wall of the paths in the DPF. Therefore, the DPF act as both a normal particulate filter and a NO.sub.x absorbent. During the operation of the engine, SO.sub.x, as well as NO.sub.x, in the exhaust gas is absorbed in the NO.sub.x absorbent in the DPF. An electronic control unit (ECU) monitors the amount of SO.sub.x absorbed in the DPF during the operation and, when the amount of SO.sub.x absorbed in one DPF increases, switches the exhaust gas flow to the other DPF. The ECU further performs the SO.sub.x recovery operation to release the absorbed SO.sub.x from the DPF. After completing the SO.sub.x recovery operation, the ECU performs the regenerating operation of the DPF in which the particulate matter trapped in the DPF is burned. Since SO.sub.x in DPF is already released by the previous SO.sub.x recovery operation when the regenerating operation of the DPF is performed, the growth of sulfate particle in the DPF does not occur even if the DPF is exposed to a high temperature lean air-fuel ratio atmosphere of the regenerating operation.
摘要翻译：在废气净化装置中，柴油发动机的排气通路分叉成两根分支管，在各支管中设置有微粒过滤器（DPF）。 DPF使用金属基材，并且NOx吸收剂附着到DPF中的路径的壁上。因此，DPF充当正常的微粒过滤器和NOx吸收剂。在发动机运转中，废气中的SOx以及NOx被DPF中的NOx吸收剂吸收。电子控制单元（ECU）监视在操作期间在DPF中吸收的SOx的量，并且当在一个DPF中吸收的SOx量增加时，将废气流切换到另一个DPF。 ECU进一步执行SOx恢复操作以从DPF释放吸收的SOx。在完成SOx恢复操作之后，ECU执行DPF中被捕获的颗粒物质燃烧的DPF的再生操作。由于在执行DPF的再生操作时，通过先前的SOx回收操作已经释放了DPF中的SOx，所以即使DPF暴露于高温稀空燃比气氛下也不会发生DPF中硫酸盐颗粒的生长的再生作业。

摘要： An exhaust purifying method and apparatus of an internal combustion engine are provided with an exhaust switch valve for switching a flow of exhaust gas flowing into an exhaust filter. By switching the exhaust switch valve, the exhaust gas is fed from one side and the other side of the filter, thereby stirring the soot (particulates) in the exhaust gas deposited on the filter having a NOx absorbent and an active-oxygen discharging agent supported thereon. Thus, the soot in the exhaust gas is continuously burned. Moreover, the switching of the exhaust switch valve and the rich spike are inhibited from being conducted simultaneously. In the case where the rich spike is conducted in order to discharge and reduce NOx absorbed in the NOx absorbent, the exhaust gas containing a large amount of HC and CO can be prevented from being discharged into the atmosphere without being purified.
摘要翻译：内燃机的排气净化方法和装置设置有用于切换流入排气过滤器的废气流的排气切换阀。通过切换排气开关阀，排气从过滤器的一侧和另一侧进料，从而搅拌沉积在具有NOx吸收剂的过滤器上的废气中的烟灰（微粒）和负载的活性氧排放剂上。因此，排气中的烟灰不断燃烧。此外，排气开关阀和丰富尖峰的切换被抑制同时进行。为了排出和减少吸收在NOx吸收剂中的NOx而进行浓穗的处理，可以防止含有大量HC，CO的废气排出到大气中而不被净化。
