Abstract

触媒温度が所定時間以上継続して低温側へ移行する場合であっても実吸着量が飽和吸着量曲線より過度に小さくなることを防ぎ、還元触媒の還元効率の低下を防止できる内燃機関の排気浄化装置の制御装置及び制御方法を提供する 還元触媒の温度推移を予測し還元触媒の温度が所定時間以上継続して低下するか否かを判定するための温度推移判定手段と、還元触媒の温度が所定時間以上継続して低下しないと判定された場合に、還元触媒の温度に対応する還元剤の飽和吸着量よりも小さい値の第１目標吸着量に応じて還元剤を噴射するための第１の噴射制御手段と、還元触媒の温度が所定時間以上継続して低下すると判定された場合に、第１目標吸着量よりも大きくかつ飽和吸着量よりも小さい値の第２目標吸着量に応じて還元剤を噴射するための第２の噴射制御手段と、を備える。
