Abstract: A RCC turbo charger is provided reduce BPF noise and vibration caused in the flow of the intake air because a reinforcing rib is installed between an outer wall and a blower case. A RCC turbo charger comprises an air intake unit which comprises an outer wall(44) and an inner wall(43) which are integrated. A slit is formed in the inner wall. The inner circumference of the outer wall and outer circumference of the inner wall are connected through plural struts(46). A noise cover is mounted on the inner circumferential surface of the top of the outer wall. Plural reinforcing ribs(70) are placed between the outer wall and blower case along the circumferential direction of the outer wall. The inner side is formed so that the top part of the inner wall is angled toward the inner side.
Abstract translation: 提供了一种RCC涡轮增压器，因为在外壁和鼓风机壳体之间安装了加强肋，从而降低了进气流动引起的BPF噪音和振动。 一种RCC涡轮增压器包括一个进气单元，该进气单元包括一个外壁（44）和内壁（43）。 在内壁形成狭缝。 内壁的内周和内壁的外周通过多个支柱（46）连接。 噪声盖安装在外壁顶部的内圆周表面上。 多个加强筋（70）沿着外壁的圆周方向放置在外壁和鼓风机壳体之间。 内侧形成为使得内壁的顶部朝向内侧成角度。

Abstract: The present invention relates to a method of compensating a position change of a vane of a variable geometry turbocharger (VGT), wherein the vane is used to control a channel area of an exhaust gas flowing in a turbine of the VGT. The method includes the steps of measuring and storing a position of the vane at the initial use of the vane; measuring and storing the position of the vane after the vane is used for a given time; calculating a difference value between the initial position of the vane and the position of the vane after use; and compensating the varied position of the vane according to the difference value. [Reference numerals] (AA) Start; (BB,DD) Yes; (CC,EE) No; (FF) End; (S100) Measure and store a position of a vane at the initial use of a VGT; (S200) Measure and store a position of the vane after the vane is used for a given time; (S300) Calculate a difference value between the initial position of the vane and the position of the vane after use (Difference value = Position of the vane after use - Initial position of the vane); (S400) Calculated difference value >= Set value for determining an abnormal state; (S500) Determine that the vane or VGT is abnormal and notify it (Replacement is required); (S600) Set value for determining a normal state
Abstract translation: 本发明涉及一种补偿可变几何涡轮增压器（VGT）的叶片的位置变化的方法，其中叶片用于控制在VGT的涡轮机中流动的废气的通道面积。 该方法包括以下步骤：在叶片的初始使用时测量和存储叶片的位置; 在给定时间使用叶片之后测量和存储叶片的位置; 计算叶片的初始位置和使用后叶片的位置之间的差值; 并且根据差值补偿叶片的变化位置。 （附图标记）（AA）开始; （BB，DD）是; （CC，EE）否; （FF）结束; （S100）在VGT的初始使用时测量并存储叶片的位置; （S200）在给定时间使用叶片后，测量并存储叶片的位置; （S300）计算叶片的初始位置和使用后的叶片的位置之间的差值（差值=使用后叶片的位置 - 叶片的初始位置）; （S400）计算出的差值> =判定异常状态的设定值; （S500）确定叶片或VGT异常并通知（需要更换）; （S600）用于确定正常状态的设定值<=计算出的差值<确定异常状态的设定值α; （S700）确定需要对叶片改变位置进行补偿并通知; （S750）补偿叶片的位置; （S800）确定叶片或VGT正常并通知（通常使用）
