Description

Technical Field

[0001] The utility model relates to automobile fuel injection nozzle detection equipment, in particular to an oil injection atomization window mechanism and an automobile fuel injection nozzle cleaning detection instrument. Background Art

[0002] In the existing automobile fuel injection nozzle cleaning and testing equipment, the following Figure 1 The window mechanism shown in the figure detects the uniformity of the atomization and the amount of fuel injected into the fuel injector. In actual applications, the most important characteristic of the GDI fuel injector is not the flow rate of the fuel injector, but the fuel distribution and atomization that form the injection pattern of the fuel injector. Inconsistent injection patterns can cause serious consequences. In traditional fuel injector cleaning and testing equipment, such as Figure 1 As shown, the uniform atomization window and the fuel injection amount window are integrated into one window 101. The space in the window 101 is relatively narrow, and the uniform atomization of the fuel injector 100 cannot be fully observed. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an oil spray atomization window mechanism and an automobile oil spray nozzle cleaning and testing instrument which can improve the dispersion degree of oil spray atomization and help observe the uniformity of atomization of the oil spray nozzle, in view of the deficiencies of the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0005] A fuel injection atomization window mechanism comprises a bracket, on which a plurality of uniform atomization windows and a plurality of fuel injection amount windows are fixed, a plurality of fuel injection nozzles are fixedly connected to the upper end of the bracket, the fuel injection nozzles correspond one-to-one with the uniform atomization windows and are interconnected, a plurality of solenoid valves are fixed to the lower end of the bracket, the solenoid valves correspond one-to-one with the fuel injection amount windows and are interconnected, the uniform atomization window corresponds one-to-one with the plurality of fuel injection amount windows and are sequentially connected up and down, and the diameter of the uniform atomization window is larger than the diameter of the plurality of fuel injection amount windows.

[0006] Preferably, the bracket includes an upper frame, a middle frame and a lower frame, a plurality of uniform atomization windows are fixed between the upper frame and the middle frame, and a plurality of oil injection amount windows are fixed between the middle frame and the lower frame.

[0007] Preferably, the bracket includes a plurality of fixed vertical rods, which pass through the upper frame, the middle frame and the lower frame in sequence, the upper ends of the fixed vertical rods are engaged and fixed with the upper frame, and the lower ends of the fixed vertical rods are screwed and fixed with the lower frame.

[0008] Preferably, there are no scale lines on the uniform atomization window, and scale lines are provided on the fuel injection amount window.

[0009] An automobile fuel injection nozzle cleaning and testing instrument comprises a housing, on which the above-mentioned fuel injection atomization window mechanism is arranged.

[0010] In the fuel injection atomization window mechanism disclosed by the utility model, the bracket serves as a supporting frame, the top end of which is used to fix and install multiple fuel injection nozzles, and the lower end of which is used to fix and install multiple solenoid valves. A group of uniform atomization windows and fuel injection amount windows are arranged between each fuel injection nozzle and the solenoid valve. The group of uniform atomization windows and fuel injection amount windows correspond to each other one by one and are interconnected. The oil mist sprayed by the fuel injection nozzle first enters the uniform atomization window and then falls into the fuel injection amount window. Since the diameter of the uniform atomization window is larger than the diameter of the multiple fuel injection amount windows, the degree of dispersion of the fuel injection atomization in the uniform atomization window is significantly improved. Compared with the prior art, the utility model helps to fully observe the uniform atomization of the fuel injection nozzle, thereby improving the detection accuracy of the automobile fuel injection nozzle cleaning tester.
