    • An oil filter (10) includes a colloidal suspension (12) of PTFE particles less than 2 microns in size retained by capillary forces within the intricacies of the filter media (26) until the filter (10) is installed and engine oil flows at first engine start up following installation. The PTFE colloidal suspension (12) is completely and immediately released into the engine lubricating system when oil flow is initiated. The PTFE colloidal suspension (12) is introduced into the oil filter (10) as one of the last manufacturing steps. Oil filter (10) is disposed vertically with its outlet port (14) at the top. A quantity of the PTFE colloidal suspension is introduced into the outlet port (14) to initially fill a portion of the volume defined by a centertube (18) and a retainer (16). The PTFE colloidal suspension passes through openings (20, 24) into contact with filter media (26). The capillary forces acting between filter media (26) and the PTFE colloidal suspension (12) cause the colloidal suspension (12) to be drawn in and retained within the intricacies of the filter media (26) fibers.
    • 油过滤器(10)包括通过在过滤介质(26)的复杂性内的毛细管力保持小于2微米的PTFE颗粒的胶体悬浮液(12),直到过滤器(10)被安装并且发动机机油首先流动 发动机在安装后启动。 当油流开始时,PTFE胶体悬浮液(12)完全立即释放到发动机润滑系统中。 将PTFE胶体悬浮液(12)作为最后的制造步骤之一引入到油过滤器(10)中。 油过滤器(10)垂直设置,其出口(14)位于顶部。 将一定量的PTFE胶体悬浮液引入出口(14)中,以初始填充由中心立方体(18)和保持器(16)限定的体积的一部分。 PTFE胶体悬浮液通过开口(20,24)与过滤介质(26)接触。 作用在过滤介质(26)和PTFE胶体悬浮液(12)之间的毛细管力使胶体悬浮液(12)被吸入并保留在过滤介质(26)纤维的复杂性中。
