Problems solved by technology

[0003] However, the existing fuel pumps for automobiles still have certain defects in use, especially for automobile fuel pumps used in certain special environments. The automobile fuel pump used in such an environment is often solved by adding automobile fuel treasure when refueling. In the process of removing carbon deposits, carbon deposits will also cause certain losses to the engine. Therefore, we propose a car fuel pump to solve the above problems

Abstract

The invention relates to the field of fuel pumps, in particular to an automobile fuel pump which comprises a shell, an oil outlet with an annular interface and an oil inlet with a square section are fixedly connected to the two sides of the shell respectively, a base with a through hole is fixedly connected to the bottom of the shell, and a sealing cover is fixedly connected to the side face of the shell through bolts. The automobile fuel pump is used for solving the problems that an existing automobile fuel pump used in the special environment that impurities in fuel are many and carbon deposit is easily formed in an engine has certain defects, and the existing automobile fuel pump used in the environment usually adopts the mode that automobile fuel is added during refueling. In this way, on one hand, impurities in fuel oil can enter the engine to cause abrasion to the engine, and on the other hand, due to regular treatment of carbon deposit, the carbon deposit can cause certain loss to the engine in the carbon deposit forming process.

Description

technical field [0001] The invention relates to the field of fuel pumps, in particular to an automobile fuel pump. Background technique [0002] The automobile fuel supply pipeline provides pressure oil, and the function of the automobile fuel pump is to deliver the fuel stored in the automobile fuel tank to the engine. [0003] However, the existing automobile fuel pump still has certain defects in use, especially the automobile fuel pump used in a certain special environment. The automobile fuel pump used in such an environment is often solved by adding automobile fuel oil when refueling, which on the one hand will cause impurities in the fuel to enter the interior of the engine, causing wear and tear to the engine, on the other hand, the regular In the process of carbon deposition removal, the carbon deposition will also cause a certain loss to the engine. For this reason, we propose an automobile fuel pump to solve the above problems. SUMMARY OF THE INVENTION [0004...
