Title
(EN) CHAIN COVER AND INTERNAL COMBUSTION ENGINE
(FR) COUVERCLE DE CHAÎNE ET MOTEUR À COMBUSTION INTERNE
(JA) チェーンカバー及び内燃機関
Abstract
(EN) Provided is a chain cover that makes it possible to stably supply a lubricating oil to a sprocket and a timing chain housed in the chain cover, without using an oil jet requiring an oil passage or an injection hole, and also provided is an internal combustion engine. The chain cover can be attached in an internal combustion engine to cover a timing chain, which transmits the driving force of a crankshaft to an intake camshaft and an exhaust camshaft, and a valve opening/closing timing control device that sets the valve timing of the intake camshaft and/or the exhaust camshaft. In the chain cover, a projecting portion that receives lubricating oil discharged from the valve opening/closing timing control device and guides the lubricating oil in the direction of the timing chain wound around the outer circumference of the valve opening/closing timing control device is present on the inner surface of the chain cover, and in a state in which the chain cover is attached, the projecting portion partially overlaps the timing chain when viewed along the rotation axis of the valve opening/closing timing control device.
(FR) L'invention concerne un couvercle de chaîne qui permet de fournir de manière stable une huile de lubrification à un pignon et à une chaîne de distribution logés dans le couvercle de chaîne, sans utiliser de jet d'huile nécessitant un passage d'huile ou un trou d'injection, et également un moteur à combustion interne. Le couvercle de chaîne peut être fixé dans un moteur à combustion interne pour couvrir une chaîne de distribution, qui transmet la force d'entraînement d'un vilebrequin à un arbre à cames d'admission et à un arbre à cames d'échappement, et un dispositif de commande du calage des soupapes d'ouverture/fermeture qui règle le calage des soupapes de l'arbre à cames d'admission et/ou de l'arbre à cames d'échappement. Dans le couvercle de chaîne, une partie en saillie qui reçoit l'huile de lubrification évacuée du dispositif de commande d'ouverture/fermeture des soupapes et qui guide l'huile de lubrification dans la direction de la chaîne de distribution enroulée autour de la circonférence externe du dispositif de commande d'ouverture/fermeture des soupapes est présente sur la surface interne du couvercle de chaîne, et dans un état où le couvercle de chaîne est fixé, la partie en saillie recouvre partiellement la chaîne de distribution lorsqu'elle est vue le long de l'axe de rotation du dispositif de commande d'ouverture/fermeture des soupapes.
(JA) オイル通路や噴射孔を必要とするオイルジェットを用いることなく、チェーンカバーに収容されたスプロケットとタイミングチェーンとに潤滑油を安定して供給し得るチェーンカバー及び内燃機関を提供する。チェーンカバーは、内燃機関において、クランクシャフトの駆動力を吸気カムシャフトと排気カムシャフトとに伝えるタイミングチェーンと、吸気カムシャフト又は排気カムシャフトの少なくとも一方のバルブタイミングを設定する弁開閉時期制御装置とを覆うように取り付け可能である。チェーンカバーは、弁開閉時期制御装置から排出される潤滑油を受け止めて弁開閉時期制御装置の外周に巻き掛けられたタイミングチェーンの方向に案内する突出部を、チェーンカバーの内面に有しており、チェーンカバーが取り付けられた状態で、突出部が、弁開閉時期制御装置の回転軸芯に沿う方向視でタイミングチェーンと一部が重複している。
