The working principle of a diesel filter is to remove impurities

The working principle of the diesel filter is mainly based on the screening effect, Brownian motion, and the "affinity" and "repulsion" effects of the filter material towards oil and water. When diesel flows through the filter, large-sized impurities are intercepted by the filter element, while small-sized particles may collide with each other through Brownian motion, increasing their apparent diameter and being filtered out. At the same time, the affinity of the filter material for oil and its repulsion effect towards water help to separate the oil flow containing tiny water droplets.
