Abstract

The invention belongs to the technical field of fuel systems of vehicles, and particularly relates to a fuel filter with an automatic water discharging function and an automatic water discharging method using the fuel filter. The fuel filter with the automatic water discharging function comprises a fuel filter body and a cup. The cup comprises an oil-water separation cavity and a water storage cavity which are partitioned from each other by a partition plate. An electromagnetic valve is arranged at the bottom of the partition plate. A first water port and a second water port are separately formed in the two sides of the electromagnetic valve. A liquid level sensor is arranged in the oil-water separation cavity. A drain pipe is arranged in the water storage cavity. The vertical position ofa water inlet of the drain pipe is located above the second water port of the electromagnetic valve. By adoption of the fuel filter with the automatic water discharging function and the automatic water discharging method, water accumulated in the cup can be automatically discharged, and damage to an engine caused when an operator forgets to discharge water manually is reduced; and air is effectively prevented from entering the fuel filter in the exhausting process, and thus, normal starting and operation of the engine are ensured.

Description

technical field [0001] The invention belongs to the technical field of vehicle fuel systems, and in particular relates to a fuel filter with an automatic water discharge function and an automatic water discharge method using the fuel filter for water discharge. Background technique [0002] The fuel filter installed on the engine or the whole vehicle is used to filter impurities in diesel oil and protect precision components such as high-pressure fuel pumps and fuel injectors. In addition to impurities in diesel oil, diesel oil also contains water, which also causes great damage to the fuel system, and even causes rust and sticking of the plunger in severe cases. Therefore, how to timely and accurately drain the moisture in the filter and prevent air from entering the filter and fuel system plays a very important role in protecting the normal operation of the entire fuel system. [0003] At present, most of the water filtered by the primary fuel filter is stored in the wate...
