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

The invention discloses a fuel oil pre-atomizer, a fuel oil atomization connector and a manufacturing method thereof. The fuel oil pre-atomizer includes a cup-shaped body with one end being a blind end and the other end being an open end. The side wall is provided with an atomizing part adjacent to the blind end and a mounting part located at the opening end of the cup-shaped body, and the side wall of the atomizing part is provided with a plurality of atomizing holes with a diameter of 10-60um; the fuel mist The atomization connector includes a straight-through connector with a stepped hole inside, and a fuel pre-atomizer is installed in the step hole; the manufacturing method of the fuel pre-atomizer includes the following steps: using a mold to stamp out a cup-shaped body with a mounting part and an atomizing part ; Process the atomization hole on the atomization part of the cup-shaped body by laser; engrave a diversion groove on the atomization part of the cup-shaped body; polish the cup-shaped body. The fuel pre-atomizer of the present invention can pre-atomize the fuel, prevent the pre-atomized fuel from forming a vortex in the nozzle, and ensure the injection pressure and atomization effect of the fuel.
Description
technical field [0001] The invention belongs to the field of fuel oil pretreatment for fuel engines, and in particular relates to a fuel oil pre-atomizer, a fuel oil atomization joint and a method for manufacturing the fuel oil pre-atomizer. Background technique [0002] The fuel injector in the high-pressure common rail fuel injection system of the existing fuel engine is provided with a slit filter element, which can only be used to roughly filter the missing impurities and cannot achieve the fine filtering and pre-atomization of the fuel, resulting in the fuel being injected into the fuel injector. The fineness and uniformity of the oil bundle in the combustion chamber are poor, which is not conducive to the full combustion of the fuel. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, a fuel pre-atomizer is needed, which can not only satisfy the fine filtration of the fuel, but also realize the pre-atomization of the fuel before it is sprayed from...
