Claims (2)
- 排気浄化触媒をケーシングにより抱持して排気系路の途中に装備し、このケーシングの出側に排気系路からの排気ガスを抜き出す出口パイプを接続すると共に、該出口パイプと前記排気浄化触媒の出側端との間に多数の散気孔を有する分散板を備えた排気浄化装置であって、前記ケーシングにおける出側端から分散板にかけての範囲にセンサを装備すると共に、該センサの検出子に向け排気ガスの流れを導き得るよう前記分散板に散気孔より大きな導風口を形成したことを特徴とする排気浄化装置。
- 分散板の導風口の出側に、該導風口を抜けた排気ガスの流れをセンサの検出子の直前位置まで案内する誘導パイプを突設したことを特徴とする請求項1に記載の排気浄化装置。
