Claims (3)
- 内燃機関(100)から排出され排気配管(300)を流れる排出ガスを浄化する排出ガス浄化装置(CA)であって、
前記排気配管に設けられ、排出ガスを通過させることで粒子状物質を補集するフィルタ(12)と、
前記フィルタの上流側と下流側との圧力差の実測値である実差圧を取得する実差圧取得部(401)と、
前記フィルタに流入する排出ガスの流量を取得する流量取得部(402)と、
正常状態の前記フィルタに、前記流量取得部によって取得した流量の排出ガスが流入した場合の前記フィルタの上流側と下流側との圧力差の計算値である計算差圧を算出する計算差圧算出部(403)と、
前記フィルタの異常判定を行う異常判定部(404)と、を備え、
前記異常判定部は、排出ガスの流量変化に伴う前記実差圧の最大値と最小値との差分を算出することにより前記実差圧の変化量を求めるとともに、排出ガスの流量変化に伴う前記計算差圧の最大値と最小値との差分を算出することにより前記計算差圧の変化量を求め、前記実差圧の変化量と前記計算差圧の変化量との比である差圧変化量比に基づいて、前記フィルタの異常判定を行うことを特徴とする排出ガス浄化装置。 - 前記異常判定部は、前記差圧変化量比と予め定められた値との乖離量が第1閾値以上となった場合に、前記フィルタに異常が生じていると判定することを特徴とする請求項1に記載の排出ガス浄化装置。
- 前記異常判定部は、排出ガスの流量が予め定められた所定時間内に第2閾値以上変化した場合に、前記フィルタの異常判定を行うことを特徴とする請求項1又は2項に記載の排出ガス浄化装置。
