Problems solved by technology

[0004] However, in practical applications, it is cumbersome to find and identify the oil path arrows on the fuel filter, and after the fuel filter has been used for a period of time, the oil path arrows are easily covered by oil stains, etc. It is easy to cause reverse connection during replacement, which will affect the function and life of the fuel filter
[0005] To sum up, how to solve the problem that the fuel filter is easily reversed has become an urgent problem to be solved by those skilled in the art

Abstract

The invention discloses a fuel line reverse connection preventing system with a fuel filter. The fuel line reverse connection preventing system with the fuel filter comprises the fuel filter, four pipelines and two connectors, wherein four fuel ports are formed in the fuel filter; each fuel port is connected with the corresponding pipeline; and a one-way valve is arranged on each pipeline. By setting of fuel line trends in the fuel filter and setting of guiding of the one-way valves, the fuel filter is optionally connected with a fuel inlet tube and a fuel outlet tube, forward connection and reverse connection are not distinguished, and therefore, reveres connection of the fuel filter is avoided. The invention further discloses a fuel filter used in the fuel line reverse connection preventing system with the fuel filter. The invention also discloses an engine which uses the fuel line reverse connection preventing system with the fuel filter.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a fuel filter anti-reverse connection oil circuit system. It also relates to a fuel filter used in the fuel filter anti-reverse connection oil circuit system. The present application also relates to an engine comprising the anti-reverse connection oil circuit system of the fuel filter. Background technique [0002] The fuel filter is a filter device responsible for filtering water and impurities in the engine to prevent impurities from causing damage and corrosion to the fuel system. The fuel filter mainly includes a housing and a filter paper. The filter paper is arranged in the housing, and the housing is provided with an oil inlet and an oil outlet on both sides of the filter paper. [0003] Since the filter paper in the fuel filter can only filter in one direction, the oil inlet of the fuel filter can only be connected to the oil inlet pipe, and the oil outlet can only be c...
