Description

Technical Field

[0001] This utility model relates to the field of fuel injector equipment technology, and in particular to a fuel engine nozzle. Background Technology

[0002] Fuel engine nozzles are key components of the engine fuel supply system. With the continuous development of the automotive and aerospace industries, the performance requirements for fuel engine nozzles are also constantly increasing.

[0003] The structural design of some traditional fuel engine nozzles is relatively cumbersome. When encountering blockage problems, complex disassembly and cleaning operations are required, which not only increases maintenance costs, but may also interfere with the normal operation of the engine due to improper operation during maintenance, thereby affecting its overall performance and reliability. In addition, some fuel nozzles do not form atomized effects when the fuel is sprayed, affecting the uniformity of fuel-air mixing and thus reducing combustion efficiency. In order to solve the above problems, this utility model provides a fuel engine nozzle. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fuel engine nozzle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fuel engine nozzle includes an injector body, a lower mounting ring fixedly connected to the upper end of the injector body, a threaded connecting pipe fixedly connected to the upper surface of the lower mounting ring, a nozzle fixedly connected to the upper end of the threaded connecting pipe, a mounting shell threaded onto the surface of the threaded connecting pipe, a plurality of oil outlet holes opened at the upper end of the nozzle, a plurality of dispersion holes opened at the upper end of the mounting shell, and a sealing mechanism fixedly connected to the lower end of the mounting shell.

[0007] As a further improvement of this utility model, the sealing mechanism includes an upper mounting ring fixedly connected to the lower end of the mounting shell, a sealing groove is provided at the upper end of the lower mounting ring, and a sealing ring adapted to the sealing groove is fixedly connected to the lower end of the upper mounting ring.

[0008] As a further improvement of this utility model, a connecting pipe is fixedly connected to the lower end of the injector body.

[0009] As a further improvement of this utility model, a solenoid valve is fixedly installed on one side of the surface of the connecting pipe, and an oil inlet pipe is fixedly connected to the other side of the surface of the connecting pipe.

[0010] As a further improvement of this utility model, a locking nut is fixedly connected to the lower end of the connecting pipe.

[0011] As a further improvement of this utility model, the lower end of the locking nut is fixedly connected to an oil return pipe.

[0012] The beneficial effects of this utility model are:

[0013] By incorporating a mounting shell and a dispersion hole, the mounting shell is rotated during use to ensure a tight connection between the mounting shell and the threaded connection pipe of the injector body. This ensures that the dispersion hole at the upper end of the mounting shell perfectly matches the oil outlet hole of the nozzle on the threaded connection pipe, allowing the fuel to be effectively dispersed during injection. This not only increases the contact area between the fuel and air but also promotes full fuel atomization, enabling the fuel to be more evenly distributed within the engine cylinder, improving combustion efficiency, reducing unburned fuel emissions, and ultimately enhancing engine performance and reducing harmful emissions.

[0014] By setting up a sealing mechanism, when the upper mounting ring at the lower end of the mounting housing and the lower mounting ring of the injector body are fully closed during use, the sealing ring between them can be fully inserted into the sealing groove to form a tight sealing structure. This effectively prevents fuel leakage, ensures the stability of the working pressure of the fuel system, and also reduces environmental pollution and safety hazards that may be caused by fuel leakage.

[0015] By incorporating a threaded connecting pipe, the mounting housing and injector body are connected via a threaded connection during use. This not only ensures a stable connection but also simplifies the installation process, requiring no complex tools or specialized skills. The mounting housing can be removed with a simple rotation, simplifying nozzle maintenance. Maintenance personnel can easily remove the mounting housing to clean the dispersion holes, effectively preventing clogging issues that may occur with prolonged use, extending the lifespan of the nozzle, and reducing the risk of engine performance degradation due to nozzle blockage.

[0016] In summary, this utility model effectively improves engine efficiency and environmental performance through innovations such as optimizing fuel atomization, enhancing sealing performance, simplifying maintenance procedures, and improving installation convenience. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A fuel engine nozzle includes an injector body 1, a lower mounting ring 2 fixedly connected to the upper end of the injector body 1, a threaded connecting pipe 3 fixedly connected to the upper surface of the lower mounting ring 2, a nozzle 4 fixedly connected to the upper end of the threaded connecting pipe 3, a mounting shell 5 threadedly fitted onto the surface of the threaded connecting pipe 3, several oil outlet holes 6 opened at the upper end of the nozzle 4, several dispersion holes 7 opened at the upper end of the mounting shell 5, and a sealing mechanism fixedly connected to the lower end of the mounting shell 5.

[0023] In this utility model, the sealing mechanism includes an upper mounting ring 8 fixedly connected to the lower end of the mounting shell 5, a sealing groove 9 opened at the upper end of the lower mounting ring 2, and a sealing ring 10 adapted to the sealing groove 9 fixedly connected to the lower end of the upper mounting ring 8. The mounting shell 5 is rotated so that it is tightly connected to the threaded connecting pipe 3 of the injector body 1 by threads. This process continues until the upper mounting ring 8 at the bottom of the mounting shell 5 and the lower mounting ring 2 of the injector body 1 are tightly fitted, ensuring that the sealing ring 10 at the lower edge of the upper mounting ring 8 is completely embedded in the sealing groove 9 of the lower mounting ring 2, forming an effective seal.

[0024] A connecting pipe 11 is fixedly connected to the lower end of the injector body 1. A solenoid valve 12 is fixedly installed on one side of the surface of the connecting pipe 11, and an oil inlet pipe 13 is fixedly connected to the other side of the surface of the connecting pipe 11. A locking nut 14 is fixedly connected to the lower end of the connecting pipe 11, and a return oil pipe 15 is fixedly connected to the lower end of the locking nut 14. When the solenoid valve 12 is activated, fuel is allowed to flow into the injector body 1 through the connecting pipe 11, and then through the threaded connecting pipe 3 and finally sprayed out from the multiple oil outlet holes 6 of the nozzle 4. Due to the precise matching between the dispersion hole 7 and the oil outlet hole 6, the sprayed fuel will be effectively dispersed, promoting more complete combustion.

[0025] When using this invention, first rotate the mounting shell 5 and thread it onto the threaded connecting pipe 3 of the injector body 1 until the upper mounting ring 8 at the lower end of the mounting shell 5 and the lower mounting ring 2 of the injector body 1 are completely closed. This allows the sealing ring 10 at the lower end of the upper mounting ring 8 to be fully inserted into the sealing groove 9 of the lower mounting ring 2. At the same time, the several dispersion holes 7 at the upper end of the mounting shell 5 will be completely matched with the several oil outlet holes 6 of the nozzle 4 on the threaded connecting pipe 3. Then, activate the solenoid valve 12 to allow fuel to enter the injector body 1 through the connecting pipe 11. Finally, the fuel passes through the threaded connecting pipe 3 and is sprayed out from the several oil outlet holes 6 of the nozzle 4. Due to the matching of the dispersion holes 7 and the oil outlet holes 6, the fuel will be sprayed out from the dispersion holes 7 and dispersed, thus achieving more complete combustion. Finally, after the device has been used for a long time, the mounting shell 5 can be easily rotated to remove it from the threaded connecting pipe 3, and the dispersion holes 7 on the mounting shell 5 can be cleaned to prevent clogging.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
