Title: (EN) EXHAUST PURIFIER OF COMPRESSION IGNITION INTERNAL COMBUSTION ENGINE
(JA) 圧縮着火式内燃機関の排気浄化装置
Abstract:
(EN) In an internal combustion engine, output of an electric motor (27) can be superposed on the output of the engine. An SOX trap catalyst (13) for capturing SOX contained in an exhaust gas is arranged in an engine exhaust gas passage in the upstream of an NOX adsorbing catalyst (14). When the SOX trap catalyst (13) is regenerated, vehicle driving force by the engine and vehicle driving force by the electric motor (27) are regulated such that the SOX concentration in the exhaust gas flowing out from the SOX trap catalyst (13) is not more than a predetermined SOX concentration during the regeneration period.

(JA) 内燃機関において、機関の出力に電気モータ（２７）による出力を重疊しうるように形成されている。ＮＯＸ吸蔵触媒（１４）上流の機関排気通路内に排気ガス中に含まれるＳＯＸを捕獲しうるＳＯＸトラップ触媒（１３）が配置される。ＳＯＸトラップ触媒（１３）を再生すべきときにはＳＯＸトラップ触媒（１３）から流出する排気ガス中のＳＯＸ濃度が再生期間中、予め定められたＳＯＸ濃度以下となるように機関による車両駆動力と電気モータ（２７）による車両駆動能力とが調整される。
