How does the oil-water separator in a vehicle work?

[LeFelicity]

The working principle of the oil-water separator in a vehicle is as follows: After the jet fuel enters the filter separator, it first gathers in an aluminum tray and then disperses into the coalescing filter element from the inside out. The specific process of the oil-water separator is: 1. The filtration layer removes solid impurities; 2. The emulsion-breaking layer separates the emulsified oil and water; 3. The coalescing layer aggregates tiny water droplets into larger ones, which settle in the water collection tank; 4. Smaller water droplets that have not yet coalesced are further separated by the hydrophobic effect of the separation filter element, settling in the sedimentation tank and being discharged through the drain valve; 5. Clean fuel passes through the separation filter element and gathers in the secondary tray, then exits through the outlet of the filter separator.
