Problems solved by technology

[0002] The fuel injector in the existing high-pressure common rail fuel injection system of the fuel engine is equipped with a slit-type filter element, which can only be used to roughly filter the missing impurities and cannot achieve fine filtration and pre-atomization of the fuel, resulting in the fuel being injected into the nozzle. The fineness and uniformity of the oil beam in the combustion chamber are poor, which is not conducive to the full combustion of fuel

Abstract

The invention discloses a fuel oil pre-atomization device, a fuel oil atomization joint and a manufacturing method of the fuel oil pre-atomization device. The fuel oil pre-atomization device comprises a cup-shaped body of which one end is a blind end and the other end is an open end. The side wall of the cup-shaped body is provided with an atomization portion adjacent to the blind end and a mounting portion located at the open end of the cup-shaped body. The side wall of the atomization portion is provided with multiple atomization holes with the pore diameter ranging from 10 micrometers to 60 micrometers. The fuel oil atomization joint comprises a straight-through connecting joint in which a step hole is formed. The fuel oil pre-atomization device is assembled in the step hole. The manufacturing method of the fuel oil pre-atomization device comprises the following steps that the cup-shaped body with the mounting portion and the atomization portion is stamped through a die; the atomization holes are machined in the atomization portion of the cup-shaped body through lasers; diversion trenches are cut in the atomization portion of the cup-shaped body; and polishing treatment is conducted on the cup-shaped body. By the adoption of the fuel oil pre-atomization device, pre-atomization can be conducted on fuel oil, the pre-atomized fuel oil can be prevented from forming an eddy in a spray head, and the injection pressure and the atomization effect of the fuel oil are guaranteed.

Description

technical field [0001] The invention belongs to the field of fuel pretreatment for fuel engines, and in particular relates to a fuel pre-atomizer, a fuel atomization joint and a method for manufacturing the fuel pre-atomizer. Background technique [0002] The fuel injector in the existing high-pressure common rail fuel injection system of the fuel engine is equipped with a slit-type filter element, which can only be used to roughly filter the missing impurities and cannot achieve fine filtration and pre-atomization of the fuel, resulting in the fuel being injected into the nozzle. The fineness and uniformity of the oil beam in the combustion chamber are poor, which is not conducive to the full combustion of the fuel. Contents of the invention [0003] In order to solve the above problems, a fuel pre-atomizer is needed, which can not only meet the fine filtration of fuel, but also realize the pre-atomization of fuel before it is sprayed from the nozzle, and at the same time...
