Description
図7に示した第2変形例に係る排気温度制御は、排気温度制御を所定期間内に2回繰り返した後に、放熱許容熱量Qmaxが大きな値となるように補正する。これにより、短期間で排気温度制御の実行と停止とが複数回繰り返されることを防止でき、ドライバビリティの悪化を防止できる。
Claims (7)
- 冷却水が流通する経路上に設けられ前記冷却水が内部を流通することにより内燃機関の排気を冷却する冷却装置と、
前記冷却装置内で前記排気から前記冷却水へと伝達する熱量を推定する熱量推定部と、
大気圧を検出する大気圧検出部と、
前記熱量が判定値を超えているか否かに基づいて前記排気の温度を抑制する排気温度制御の実行の可否を決定すると共に、前記大気圧が低いほど前記判定値が小さくなるように補正する機関制御部と、を備えた内燃機関の制御装置。 - 前記機関制御部は、前記排気温度制御実行中での前記判定値を、前記排気温度制御を実行していない時の前記判定値よりも小さくなるように補正する、請求項1の内燃機関の制御装置。
- 前記機関制御部は、前記排気温度制御の完了後の所定期間内での前記判定値を、前記排気温度制御実行中での前記判定値よりも大きくなるように補正する、請求項1の内燃機関の制御装置。
- 前記機関制御部は、前記大気圧に応じて前記判定値の補正量を変更する、請求項2又は3の内燃機関の制御装置。
- 前記機関制御部は、前記大気圧が低いほど、前記判定値の補正量を大きくする、請求項2の内燃機関の制御装置。
- 前記機関制御部は、前記大気圧が低いほど、前記判定値の補正量を小さくする、請求項3の内燃機関の制御装置。
- 前記機関制御部は、前記冷却水の放熱可能な熱量に基づいて前記判定値を算出する、請求項1乃至6の何れかの内燃機関の制御装置。
