Abstract

The invention discloses a fuel filter, and relates to the technical field of vehicle fuel filter systems, the fuel filter comprises a main shell and a filter cartridge, the main shell is provided with an oil inlet and an oil outlet; the filter cartridge is internally provided with a filter assembly, and the filter assembly comprises a first filter assembly and a second filter assembly; a first cavity is formed between the first filtering assembly and the inner wall of the main shell, the first cavity communicates with the fuel inlet, and the first filtering assembly can filter particulate matter in fuel oil; a water outlet is further formed in the main shell, a second cavity is formed between the first filtering assembly and the second filtering assembly, the second cavity communicates with the water outlet, and the second filtering assembly can filter water in fuel oil; a third cavity is formed in the inner side of the second filtering assembly and communicates with the oil outlet. According to the invention, the effects of impurity filtration and oil-water separation can be realized, and the problem of corrosion of components in a fuel system in the use process of a vehicle is effectively solved.

Description

technical field [0001] The invention relates to the technical field of vehicle fuel filter systems, in particular to a fuel filter. Background technique [0002] With the popularization of lightweight components and the achievement of low fuel consumption goals, and the reduction of vehicle failures caused by fuel system problems, lightweight fuel filters under positive pressure conditions are gradually being applied to small and medium-power engines. [0003] However, the existing fuel filter can usually only filter the particulate matter and large-diameter water droplets in the fuel, but cannot filter the fine and tiny water droplets in the fuel, so as to achieve high-precision and long-term oil-water separation; the unfiltered fine and tiny water droplets in the fuel If it enters the fuel system, it is easy to rust the components, which further leads to failures such as engine stall and difficulty in starting. [0004] Therefore, a new type of fuel filter is provided to ...
