Description
図1は、本発明の第1実施形態による内燃機関100、及び内燃機関100を制御する電子制御ユニット200の概略構成図である。
次に、本発明の第2実施形態について説明する。本実施形態は、PMフィルタ34b内のPM堆積量が少なくなったときに、PMフィルタ34bの隔壁343を加熱することによってPMを間接的に加熱して燃焼除去する点で、第1実施形態と相違する。以下、その相違点を中心に説明する。
次に、本発明の第3実施形態について説明する。本実施形態は、PMフィルタ34b内のPM堆積量が少なくなったときに、マイクロ波の周波数fを高くして、筐体34aの入口端からその内部に進入するマイクロ波の分散を促進させる点で、第1実施形態と相違する。以下、その相違点を中心に説明する。
34a 筐体
34b PMフィルタ(フィルタ)
35 マイクロ波照射装置
100 内燃機関
200 電子制御ユニット(制御装置)
Claims (1)
