| description | PROBLEM TO BE SOLVED: To provide an exhaust gas recirculation control device for an engine, for controlling the recirculation amount of exhaust gas through an EGR passage 81 by means of the opening of an EGR valve 83 arranged in the EGR passage 81 and the opening of an exhaust shutter valve 43 arranged on the further downstream side than a connection part of an exhaust passage 40 to the EGR passage 81, while improving the responsiveness of a change of an actual recirculation amount with changes in the openings of the EGR valve 83 and the exhaust shutter valve 43, to a change of a target recirculation amount.SOLUTION: A valve control device executes: EGR valve opening control to determine the opening of the EGR valve 83, supposing that the exhaust shutter valve 43 is fully opened, and to control the opening of the EGR valve 83 as determined; and exhaust shutter valve opening control to determine the opening of the exhaust shutter valve 43, supposing that the EGR valve 83 is fully opened, and to control the opening of the exhaust shutter valve 43 as determined, independently of each other.SELECTED DRAWING: Figure 1
【課題】ＥＧＲ通路８１による排気ガスの還流量を、ＥＧＲ通路８１に配設されたＥＧＲ弁８３の開度、及び、排気通路４０におけるＥＧＲ通路８１の接続部分よりも下流側に配設された排気シャッター弁４３の開度により制御する場合に、目標還流量の変化に対する、ＥＧＲ弁８３及び排気シャッター弁４３の開度変化に伴う実還流量の変化の応答性を向上させる。【解決手段】弁制御装置が、排気シャッター弁４３が全開であるとしてＥＧＲ弁８３の開度を決定して該ＥＧＲ弁８３を該決定した開度に制御するＥＧＲ弁開度制御と、ＥＧＲ弁８３が全開であるとして排気シャッター弁４３の開度を決定して該排気シャッター弁４３を該決定した開度に制御する排気シャッター弁開度制御とを互いに独立して実行する。【選択図】図１ |
