Title (EN) OIL SUPPLY DEVICE OF INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF D'ALIMENTATION EN HUILE D'UN MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関のオイル供給装置
Abstract:
(EN) Provided is an oil supply device of an internal combustion engine, the device comprising a control unit that controls the operation of an electric oil pump, the control unit constituting: an oil remaining-amount estimation device that estimates the amount of oil remaining in an auxiliary chamber; or an oil remaining-amount detection device that detects the amount of oil remaining. In a state in which the internal combustion engine is stopped, when the remaining anount of oil in the auxiliary chamber is estimated to be or detected to be less than or equal to a prescribed remaining oil amount, the control unit causes the electric oil pump to operate, thereby performing oil refilling control to refill the auxiliary chamber with oil.
(FR) L'invention concerne un dispositif d'alimentation en huile d'un moteur à combustion interne, le dispositif comprenant une unité de commande qui commande le fonctionnement d'une pompe à huile électrique, l'unité de commande se composant : d'un dispositif d'estimation de quantité restante d'huile qui estime la quantité d'huile restant dans une chambre auxiliaire : ou d'un dispositif de détection de quantité d'huile restante qui détecte la quantité d'huile restante. Dans un état dans lequel le moteur à combustion interne est arrêté, lorsque la quantité restante d'huile dans la chambre auxiliaire est estimée être ou est détectée comme étant inférieure ou égale à une quantité d'huile restante prescrite, l'unité de commande fait fonctionner la pompe à huile électrique, effectuant ainsi une commande de remplissage d'huile pour remplir d'huile la chambre auxiliaire.
(JA) 内燃機関のオイル供給装置は、電動式オイルポンプの作動を制御するコントロールユニットであって、副室のオイル残量を推定するオイル残量推定装置又は該オイルの残量を検出するオイル残量検出装置を構成するコントロールユニットを備えている。コントロールユニットは、内燃機関が停止状態であるときにおいて、副室内のオイルの残量が所定オイル残量以下となったことが推定又は検出されたときに、電動式オイルポンプを作動させて、副室にオイルを補充するオイル補充制御を実行する。
