The Property of Automobile Engine Oil Filtration Material and the Development of New Filter

The main purposes of this paper are to research the structure and property of commonly used oil filtration materials on the basis of the hierarchical cluster method and to develop new filter material. For this objective we selected ten different oil filtration materials and made a comparison of their filtration properties. In addition, the hierarchical cluster method was used to classify these ten oil filtration materials into three different categories. Objective classification results in the case of data matrix of different properties had a rather accurate result, which was almost consistent with the result of subjective classification. It was found that three different kinds of filtration material had different structures and properties in practical application. In addition, the results indicate that the filtration property of the new filter developed on the basis of hierarchical cluster analysis was very close to the first material.
