Title (EN) EXHAUST GAS PURIFICATION SYSTEM AND FUEL SUPPLY METHOD
(FR) SYSTEME DE PURIFICATION DE GAZ D'ÉCHAPPEMENT ET PROCÉDÉ D'ALIMENTATION EN CARBURANT
(JA) 排ガス浄化システム及び燃料供給方法
Abstract:
(EN) In the present invention, when there has been a PM collection filter 7 regeneration request , an ECU 14 closes a flow rate regulation valve 12 and then starts up an electromagnetic pump 11 that pressure-feeds unburned fuel 10 to an injector 8. Subsequently, the ECU 14 performs control to adjust the number of rotations of the electromagnetic pump 11 on the basis of preset map data so that a measurement value X of a pressure sensor 13 matches a target pressure value A within a predetermined range.
(FR) Dans la présente invention, lorsqu'il y a eu une requête de régénération d'un filtre 7 de collecte de PM, une unité de commande électronique 14 ferme une soupape 12 de régulation de débit et démarre ensuite une pompe électromagnétique 11 qui fournit sous pression du carburant non brûlé 10 à un injecteur 8. Par la suite, l'unité de commande électronique 14 effectue une commande pour ajuster le nombre de rotations de la pompe électromagnétique 11 sur la base des données de carte pré-établies de sorte qu'une valeur de mesure X d'un capteur de pression 13 correspond à une valeur de pression cible A située à l'intérieur d'une plage prédéfinie.
(JA) ECU14は、PM捕集フィルター7の再生要求があったときは、流量調整弁12を閉弁してから、インジェクタ8に未燃燃料10を圧送する電磁ポンプ11を起動した後に、圧力センサ13の測定値Xが目標圧力値Aと所定の範囲内で一致するように、予め設定されたマップデータに基づいて電磁ポンプ11の回転数を調節する制御を行う。
