Abstract
【解決手段】作業機140に搭載されるエンジン70と、エンジン70の排気系77に配置された排気ガス浄化装置50と、排気ガス浄化装置50内の粒子状物質を燃焼除去するための再生装置70,81,82,117とを備える。排気ガス浄化装置50の詰り状態が規定水準以上の場合に再生装置70,81,82,117を作動可能にする。再生装置70,81,82,117の作動を許可する再生許可入力手段21と、エンジン70の回転速度Nを所定回転速度Nmに保持するための回転速度保持入力手段27とを備える。再生許可入力手段21の許可操作をした状態で回転速度保持入力手段27の入り操作をした場合は、エンジン70の回転速度保持動作を前記再生装置70,81,82,117の作動に優先して実行する。
【選択図】図8
Description
まず始めに、図1及び図2を参照して、エンジン70が搭載される作業機の一例であるバックホウ141の概略構造について説明する。なお、図2では説明の便宜上、キャビン146の図示を省略している。
次に、図3及び図4を参照しながら、エンジン70及びその周辺の構造を説明する。図4に示すように、エンジン70は前述の通り、4気筒型のディーゼルエンジンであり、上面にシリンダヘッド72が締結されたシリンダブロック75を備えている。シリンダヘッド72の一側面には吸気マニホールド73が接続されており、他側面には排気マニホールド71が接続されている。シリンダブロック75の側面のうち吸気マニホールド73の下方には、エンジン70の各気筒に燃料を供給するコモンレールシステム117が設けられている。吸気マニホールド73の吸気上流側に接続された吸気管76には、エンジン70の吸気圧(吸気量)を調節するための吸気絞り装置81とエアクリーナ(図示省略)とが接続される。
次に、図3、図6及び図7等を参照しながら、エンジン70の制御関連の構成を説明する。図3に示す如く、エンジン70における各気筒の燃料噴射バルブ119を作動させるECU11を備えている。ECU11は、各種演算処理や制御を実行するCPU31の他、各種データを予め固定的に記憶させたROM32、制御プログラムや各種データを書換可能に記憶するEEPROM33、制御プログラムや各種データを一時的に記憶するRAM34、時間計測用のタイマ35、及び入出力インターフェイス等を有しており、エンジン70又はその近傍に配置される。
次に、図8のフローチャート等を参照しながら、ECU11によるDPF50再生制御の一例について説明する。さて、エンジン70の制御モード(DPF50再生に関する制御形式)としては少なくとも、路上走行や各種作業をする通常運転モードと、DPF50の詰り状態が規定水準以上になると、再生スイッチ21を押下した場合に排気ガス温度を上昇させる手動補助再生モードと、ポスト噴射EにてDPF50内に燃料を供給する強制再生モードとがある。
上記の記載並びに図3、図7及び図8から明らかなように、作業機140に搭載されるエンジン70と、前記エンジン70の排気系77に配置された排気ガス浄化装置50と、前記排気ガス浄化装置50内の粒子状物質を燃焼除去するための再生装置70,81,82,117とを備えており、前記排気ガス浄化装置50の詰り状態が規定水準以上の場合に前記再生装置70,81,82,117が作動可能になっている排気ガス浄化システムであって、前記再生装置70,81,82,117の作動を許可する再生許可入力手段21と、前記エンジン70の回転速度Nを所定回転速度Nmに保持するための回転速度保持入力手段27とを備えており、前記再生許可入力手段21の許可操作をした状態で前記回転速度保持入力手段27の入り操作をした場合は、前記エンジン70の回転速度保持動作を前記再生装置70,81,82,117の作動に優先して実行するように構成されているから、前記再生許可入力手段21の許可操作をしていたとしても、前記回転速度保持入力手段27の入り操作によって、前記排気ガス浄化装置50の再生動作を禁止できる。これに加えて、前記エンジン70の駆動状態を、オペレータがエンジン音を頼りに実行する緻密作業に適した回転速度に保持できる。すなわち、前記作業機140の作業状態等に応じオペレータの意思によって、前記排気ガス浄化装置50の再生動作を禁止しながら、前記エンジン70の駆動状態を前記緻密作業に適した回転速度に保持できる。従って、前記排気ガス浄化装置50の粒子状物質捕集能力を回復させる再生制御を実行可能なものでありながら、前記緻密作業をスムーズに行える。つまり、前記緻密作業を阻害しかねない前記排気ガス浄化装置50再生動作の欠点をなくして、前記緻密作業を集中して行えるという効果を奏する。
本願発明は、前述の実施形態に限らず、様々な態様に具体化できる。各部の構成は図示の実施形態に限定されるものではなく、本願発明の趣旨を逸脱しない範囲で種々変更が可能である。
