The automobile oil-water separator is a kind of fuel filter. Its main function is to remove the moisture in the diesel, so as to reduce the failure of the fuel injection nozzle and prolong the service life of the engine. The principle is mainly based on the density difference between water and fuel, a separator that uses the principle of gravity sedimentation to remove impurities and moisture. There are also separation elements such as a diffusion cone and a filter inside. The oil-water separator also has other functions, such as pre-heating the fuel to prevent wax formation and filtering impurities.
