    摘要： An NO.sub.x absorbent (18) is disposed in an exhaust passage of an internal combustion engine and the exhaust gas is constantly made to circulate through the NO.sub.x absorbent (18) during the operation of the engine. The NO.sub.x absorbent (18) absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (18) is lean and releases the absorbed NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (18) becomes the stoichiometric air-fuel ratio or rich. In the majority of the engine operation region, the lean air-fuel mixture is burned in the combustion chamber (3), and the NO.sub.x generated at this time is absorbed into the NO.sub.x absorbent (18). The air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (18) is periodically made the stoichiometric air-fuel ratio or rich, and the NO.sub.x absorbed in the NO.sub.x absorbent (18) is released, and simultaneously reduced.

    摘要： A NO.sub.x absorbent which absorbs NO.sub.x in exhaust gas when the air-fuel ratio of the exhaust gas is lean and releases absorbed NO.sub.x when the oxygen concentration of the exhaust gas is lowered, is disposed in an exhaust passage of an engine. When the amount of the NO.sub.x absorbed by the NO.sub.x absorbent is increased, the regenerating process of the NO.sub.x absorbent is performed by supplying a reducing agent to the NO.sub.x absorbent so that the NO.sub.x absorbed by the NO.sub.x absorbent is released and reduced by the reducing agent. Usually, to reduce the amount of the reducing agent required for the regenerating process, the inflowing exhaust gas into the NO.sub.x absorbent is shut off. In the present invention, even in the regenerating process of NO.sub.x absorbent, a small amount of the exhaust gas (carrier gas) is introduced to the NO.sub.x absorbent to carry the supplied reducing agent through the NO.sub.x absorbent to thereby reduce the amount of the reducing agent required for the regenerating process and to shorten the time required to complete the regenerating process.

    摘要翻译： 当排气的空燃比为稀的时，吸收排气中的NOx的NOx吸收剂，排气的氧浓度降低时吸收的NOx排出在发动机的排气通路内。 当NOx吸收剂吸收的NOx的量增加时，NOx吸收剂的再生过程是通过向NOx吸收剂供给还原剂来进行，以使由NOx吸收剂吸收的NOx被还原剂释放和还原。 通常，为了减少再生处理所需的还原剂的量，关闭向NOx吸收剂中流入的废气。 在本发明中，即使在NOx吸收剂的再生过程中，少量废气（载气）被引入到NOx吸收剂中，从而通过NOx吸收剂输送供给的还原剂，从而减少还原剂的量 需要再生过程并缩短完成再生过程所需的时间。

    摘要： An exhaust-gas purifying apparatus according to the present invention comprises an exhaust-gas filter for trapping particulates in exhaust gas from an engine, and a heating device located on the upper-course side of the filter, with respect to the flowing direction of the exhaust gas, the heating device including one or more conductive-ceramic heater elements, capable of heating and burning the particulates caught by the filter, and a heater case for holding the heater elements in position, so that the caught particulates are heated and burned by the heater elements when the flow resistance of the exhaust gas, flowing through the filter, is increased by the caught particulates, whereby the flow resistance is reduced. The heater element includes a fixed electrode portion, immovably fixed to the heater case, and a slidable electrode portion held slidably. An electrode member, fixed to the heater case, is brazed to the fixed electrode portion, and the heater element is bonded to the electrode member, so as to be clamped from both sides by solidified molten solder. The slidable electrode portion is supported by the heater case, for sliding motion in the direction of thermal deformation, so that the working life of the heater element is prolonged.

In the particulate trap, the difference in width between the nonwoven sheet and the corrugated plate is larger in a central zone of the particulate trap than in the circumferential zone thereof.
