    摘要： Friction reducing units are integrally configured in a tensioner arm and a chain guide that are disposed at both sides of a timing chain to make contact with the timing chain, respectively to increase the thickness of the oil film, such that it is possible to improve durability of an entire timing chain system while preventing noise from being generated by reducing a friction loss generated on each of contact surfaces of the tensioner arm and the chain guide and prevent fuel efficiency of the vehicle from being deteriorated.Provided is a friction reducing device of a timing chain for a vehicle in a timing chain system including a tensioner arm and a chain guide disposed at both sides of a timing chain interconnecting a crank sprocket mounted a crank shaft and a cam sprocket mounted on the cam shaft so as to transfer a rotational force of the crank shaft to a cam shaft, respectively to prevent the timing chain from being separated while reducing vibration of the timing chain, wherein the tensioner arm and the chain guide further include first and second friction reducing units integrally formed, respectively in order to reduce a friction loss by increasing the thickness of an oil film between each of contact surfaces that make sliding-contact with the timing chain.

    摘要翻译： 摩擦减少单元一体地构造在分别布置在正时链的两侧以与正时链接触的张紧器臂和链条引导件中，以增加油膜的厚度，使得可以提高耐久性 的整个正时链系统，同时通过减少在张紧器臂和链条引导件的每个接触表面上产生的摩擦损失来防止噪声产生，并且防止车辆的燃料效率劣化。 本发明提供一种正时链系统中的车辆正时链的减摩装置，包括：张紧器臂和链条引导件，其布置在连接安装在曲柄轴上的曲柄链轮和安装在凸轮上的凸轮链轮的正时链的两侧 以便分别将曲柄轴的旋转力传递到凸轮轴，以防止正时链条分离，同时减少正时链条的振动，其中张紧器臂和链条引导件还包括第一和第二摩擦减小单元 分别一体地形成，以通过增加与正时链滑动接触的每个接触表面之间的油膜的厚度来减小摩擦损失。

    摘要： An engine chain cover wherein a passage for passing the blow-by gas is formed at one side of the chain cover to shorten the manufacturing process of a cylinder head and save manufacturing costs, and some of the oil is separated from the blow-by gas when the blow-by gas passes through the passage of the chain cover to thereby improve the separation efficiency of the oil.
