Abstract: An exhaust system (10) for a vehicular lean-bum internal combustion engine (12) comprises a NO x reduction catalyst (18), a source of reductant, means (20) for contacting the catalyst (18) with the reductant, means (TC1) for sensing the temperature of the exhaust gas and/or the catalyst bed and means, when in use, for controlling reductant addition, wherein the reductant addition control means supplies an amount of reductant to the catalyst at a rate corresponding to a measured temperature value of the exhaust gas and/or catalyst bed, which temperature value has been pre-determined to correlate, in use, with an amount of NO x in the exhaust gas.

Abstract: A process for treating an exhaust gas of a lean-bum reciprocating internal combustion engine comprising the steps of collecting particulate matter (PM) on a first filter (26) and combusting a carbon fraction thereof, periodically reversing the direction of gas flow through the first filter (20) thereby displacing uncombusted PM from the erstwhile upstream side thereof and collecting at least part of the displaced PM on a second filter (34).
Abstract translation: 一种用于处理贫燃循环内燃机的排气的方法，包括以下步骤：在第一过滤器（26）上收集颗粒物质（PM）并燃烧其碳分数，周期性地逆转通过第一 过滤器（20），从而将未燃烧的PM从其上游侧排出，并将至少部分位移的PM收集在第二过滤器（34）上。

Abstract: A method of treating an exhaust gas of a lean-burn reciprocating engine comprises sorbing NO x on at least one NO x sorber (30A; 30B) when the exhaust gas is lean, intermittently contacting the at least one NO x sorber with an agent effective to convert NO x to N 2 , thereby to regenerate the at least one NO x sorber and feeding effluent of said intermittent contacting step to the engine inlet (14).
Abstract translation: 一种处理贫燃往复式发动机的废气的方法包括当排气稀的时候在至少一个NOx吸附器（30A; 30B）上吸附NOx，间歇地使至少一个NOx吸附剂与有效转化NOx的试剂接触 从而使所述至少一个NOx吸附器再生并将所述间歇接触步骤的流出物进料到所述发动机入口（14）。
