    • An improved oil conditioning filter, for use with an internal combustion engine, includes a mechanically active filter element and a chemically active filter element having a reactive basic conditioner therein. The reactive basic conditioner is provided to counteract acidic combustion products in lubricating oil in an internal combustion engine. In a preferred embodiment of the invention, the chemically active conditioning agent is provided in a plurality of pellets disposed within the oil filter housing. The pellets may be bonded together to form an integral porous filter element having spaced defined between the pellets thereof. The pellets are made of a mixture including a polymeric binder and the chemically active conditioning agent, in a defined weight ratio and in a narrow range of particle sizes. The chemically active filter element reacts with acids present in the oil to form a product which may be filtered out of the oil. The pellets are made either by a hot extrusion process or by a solvent process.
    • 用于内燃机的改进的油调节过滤器包括机械活性过滤元件和在其中具有反应性碱性调理剂的化学活性过滤元件。 提供反应性碱性调理剂以抵消内燃机中的润滑油中的酸性燃烧产物。 在本发明的优选实施方案中,化学活性调理剂设置在设置在机油过滤器壳体内的多个颗粒中。 颗粒可以结合在一起以形成在其颗粒之间具有间隔开的整体多孔过滤元件。 颗粒由包含聚合物粘合剂和化学活性调理剂的混合物以确定的重量比和窄的粒度范围制成。 化学活性过滤元件与油中存在的酸反应形成可从油中过滤出来的产物。 颗粒通过热挤压方法或通过溶剂方法制成。
