Abstract: PURPOSE: An intercooler of a vehicle is provided to supply cooling air into a cylinder by promoting the heat exchange between outdoor air and indoor air by installing a guide blade at the inlet of an intercooler. CONSTITUTION: An intercooler of a vehicle comprises a guide blade(180). The guide blade is installed within an inlet side tank(130) of an intercooler. The air flowed through an inlet is direction-converted toward a tube while passing the inside of a tank. The guide blade prevents the breaking phenomenon of the flow due to the flow rate difference of the inside and outside by guiding the flow of the air. A through hole(181) is formed in the guide blade and is connected to the outside to flow the outdoor air.

Abstract: 본 발명은 자동차 엔진의 4-1 타입 배기 매니폴드 구조에 관한 것으로, 각 런너에서 가이드 관부와 만나는 부분이 소정의 경사각으로 기울어진 형태로 구성되어, 이 기울어진 부분을 통해 배기가스가 가이드 관부로 유입시 경사방향으로 유도되도록 함으로써, 배기가스의 간섭이 최소화 될 수 있고, 이를 통해 배기가스 유동 흐름의 성능이 향상될 수 있는 한편 각 런너와 가이드 관부가 만나는 부분의 통로 단면적이 각 기통에 연결된 런너 입구의 통로 단면적(플랜지의 포트 단면적)에 비해 감소된 구조로 구성됨으로써, 런너와 가이드 관부가 만나는 부분에서의 배기가스 속도가 종래에 비해 증가될 수 있고, 이를 통해 배기가스 배출시의 간섭효과를 최대한 줄일 수 있는 장점을 가진 엔진의 배기 매니폴드 구조에 관한 것이다.
이와 같이, 가이드 관부와 만나는 런너 부분에 경사각이 설정, 적용된 본 발명의 4-1 타입 배기 매니폴드를 사용하는 경우, 가이드 관부와 런너가 직선의 90°각도로 연결된 종래의 4-1 타입 배기 매니폴드를 사용하는 경우에 비해 엔진의 전 부분에서의 성능 향상을 기대할 수 있다.-

Abstract: PURPOSE: A resonator for offsetting intake noise of a surge tank is provided to change noise offset frequency depending on working state of an engine. CONSTITUTION: A resonator(4) is connected with a surge tank(1) through two neck parts(5,6). One of the neck parts is a low speed channel(8) with smaller sectional area(A1) and longer length(L1). The other of the neck parts is a high speed channel(9) with larger sectional area(A2) and shorter length(L2). A valve(10) rotates centering on a hinge axis(11) to selectively open and close the channels and rotated by an actuator. The lengths and sectional areas of the neck parts of the resonator are designed correspondingly with characteristic operation area of an engine, for example, low speed of 2000RPM and high speed of 3500RPM. An electronic control unit detects through an RPM sensor when the engine runs at low speed, and controls an actuator so that the valve cuts off the high speed channel and opens the low speed channel. The resonator and the surge tank are connected through the low speed channel thereby to damp noise frequency corresponding with the RPM. The electronic control unit controls the actuator when the engine runs at high speed so that the valve cuts off the low speed channel and opens the high speed channel. The resonator and the surge tank are connected through the high speed channel to damp noise frequency corresponding with the RPM.
Abstract translation: 目的：提供用于抵消缓冲罐的进气噪声的谐振器，以根据发动机的工作状态改变噪声偏移频率。 构成：谐振器（4）通过两个颈部部件（5,6）与缓冲罐（1）连接。 颈部之一是具有较小截面面积（A1）和较长长度（L1）的低速通道（8）。 颈部的另一个是具有较大截面面积（A2）和较短长度（L2）的高速通道（9）。 阀（10）以铰链轴线（11）为中心旋转，以选择性地打开和关闭通道并由致动器旋转。 谐振器的颈部的长度和截面面积相应地设计为发动机的特征操作区域，例如2000RPM的低速度和3500RPM的高速度。 当发动机以低速运转时，电子控制单元通过RPM传感器进行检测，并且控制致动器，使得阀切断高速通道并打开低速通道。 谐振器和缓冲罐通过低速通道连接，从而抑制与RPM对应的噪声频率。 当发动机高速运转时，电子控制单元控制执行机构，使阀门切断低速通道并打开高速通道。 谐振器和缓冲罐通过高速通道连接到与RPM对应的噪声频率。
