摘要： An intake system of an engine may include an intake line that is configured to supply cylinder of an engine with air, an exhaust line that exhaust gas combusted in the cylinder is exhausted, a housing disposed on the intake line and a compressor is disposed therein, the compressor is operated by a turbine disposed on an exhaust line, a recirculation line that recirculates the air from the intake line of a downstream side of the compressor to the intake line of an upstream side of the compressor, and an anti surge valve disposed on the recirculation line to open/close the recirculation line, wherein a length of a first section (l) that is straight from the anti surge valve is longer than two times the outlet diameter (d) of the anti surge valve in the recirculation line that is formed from the anti surge valve to an upstream side of the compressor.A distance (L) from the intake line that is connected to the recirculation line to the inlet of the housing may be longer than times the inlet diameter (D) of the housing that the compressor is disposed therein.Accordingly, while the intake air circulates the anti surge valve during a tip-out or acceleration period, the turbulent flow may be decreased and the flowing becomes smooth such that the noise is decreased and the emotional quality may be improved in the intake system of the engine.
摘要翻译：发动机的进气系统可以包括：进气管，其被构造成供应发动机的气缸的空气;排气管，其中在所述气缸中燃烧的排气被排出;设置在所述进气管上的壳体和设置在其中的压缩机，压缩机由设置在排气管上的涡轮机，使空气从压缩机的下游侧的进气管路再循环到压缩机的上游侧的进气管线的再循环管路，以及设置在压缩机的上游侧的防喘振阀所述再循环管线用于打开/关闭所述再循环管线，其中从所述防喘振阀直线的第一部分（l）的长度长于所述再循环管线中的所述防喘振阀的出口直径（d）的两倍，由防喘振阀形成到压缩机的上游侧。与再循环管线连接到壳体入口的进气管线的距离（L）可以比压缩机设置在其中的壳体的入口直径（D）的时间长。因此，在抽出或加速期间吸入空气使防喘振阀循环的同时，可以减少湍流，并且流动变得平滑，使得噪音降低，并且可以改善吸入系统的情绪质量发动机。
