Abstract
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、圧力波生成処理を1度実施してもアッシュを十分に剥離できていないと判断できるときは、繰り返し圧力波生成処理を実施する点で第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。
42 排気通路
44 シャット弁
71 パティキュレートフィルタ(フィルタ)
100 内燃機関
200 電子制御ユニット(制御装置)
Claims (1)
- 機関本体と、
前記機関本体の排気通路に設けられて排気中の粒子状物質を捕集するフィルタと、
前記フィルタよりも排気流れ方向下流側の前記排気通路に設けられて当該排気通路を閉塞させるシャット弁と、
を備える内燃機関を制御するための内燃機関の制御装置であって、
前記フィルタに付着したアッシュの付着力と相関関係にあるパラメータに基づいて、前記アッシュの付着力を推定する付着力推定部と、
前記シャット弁によって前記排気通路を一時的に閉塞することで、前記排気通路を前記シャット弁から排気流れ方向上流側に向かって伝播する圧力波を生成する圧力波生成制御部と、
を備え、
前記圧力波生成制御部は、
前記シャット弁によって前記排気通路を一時的に閉塞するときは、前記アッシュの付着力に基づいて、前記機関本体から排出される排気の流量を制御するか、又は前記シャット弁の作動速度を制御する、
内燃機関の制御装置。
