Fuel filter assembly

Abstract

The invention discloses a fuel filter assembly. The fuel filter assembly comprises an upper shell component, a filter element component and a lower shell component, wherein the upper shell component comprises a main body part, a cylindrical rotary cover and a pressing cover part; the lower shell component comprises a lower shell part and an electric integration module, wherein the electric integration module comprises a horizontally arranged partition plate, the center of the partition plate is provided with an upper central column, the top of the upper central column is provided with a fuel temperature sensor, the center of the partition plate is downwards provided with a lower wire outlet barrel, electric heaters are arranged on the upper surface of the partition plate, the electric heaters are connected with a temperature control switch, and the lower wire outlet barrel penetrates through a sealing barrel downwards, and the lower end of the lower wire outlet barrel is flush with a circuit outlet; and the bottom wall of the lower shell part is upwards provided with a lower connecting column, and the partition plate is fixedly connected with a lower connecting column through a connecting bolt. According to the fuel filter assembly, the assembling process is facilitated, the assembling efficiency is improved, and solves the problems of flameout of a motor vehicle and the motorvehicle is not prone to reignition after flameout.

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] The three filters for automobiles refer to air filters, fuel filters and oil filters. The "three filters" filter the air, oil and fuel on the car engine, thus protecting the engine. [0003] In recent years, emission regulations and standards have been continuously improved. Automobile manufacturers and engine manufacturers have put forward the target requirements of light weight, modularization, integration and low emission. The original metal auto parts are gradually replaced by organic engineering plastics. "Filter" products are more and more replaced by molded case air filter, molded case fuel filter and molded case oil filter products. The use of organic engineering plastics as raw materials for production not only meets the requirements of national environmental protection regulations, but also can greatly r...

AI Technical Summary

Problems solved by technology

These products have imperfections, such as low integration of components, heaters and water level sensors are independent interfaces, and there is no modular division of filter components, which makes the existing filter assembly and installation difficult. It is more complicated, the disassembly and installation when replacing the filter element is more cumbersome, the filter seal needs to be further improved, etc.

Another example is that when the fuel passes through the filter layer, a small amount of gas contained in the fuel will accumulate at the center tube of the filter element. After a large amount of accumulated gas, it will flow into the motor vehicle oil as the fuel passes through the center tube of the filter element and the oil outlet pipe at one time. road, causing the motor vehicle to stall, and it is not easy to re-ignite after stalling
