The key function of automobile oil-water separator is to separate the water in the fuel, then the fuel will be fully burned in the engine cylinder, so that the engine can work better.

Gasoline oil-water separator is a kind of fuel filter, including membrane filtration oil-water separator, lipophilic material oil-water separator, unpowered oil-water separator, demulsifier oil-water separator, etc.

The working process of oil-water separator in automobile is as follows：

1. After the fuel enters the filter separator, the solid impurities are filtered out by the filter layer.
2. In the demulsification layer, the emulsified oil and water are separated.
3. In the oil-water separator, small water droplets will condense into large water droplets and remain in the sump.
4. Through the water repellent effect of the separation filter element, the small water drops that have not been condensed in time are collected into the sedimentation tank, and then discharged from the drain valve.
5. Finally, the fuel that has been separated out of water is discharged from the filter separator.

Notes on vehicle fuel:

1. Adding high-grade fuel as much as possible can prolong the service life of the engine to a certain extent.
2. It is impossible to mix different types of fuel.
