Problems solved by technology
At present, the detection of the atomization shape, injection angle, and injection distance of the fuel injector has been carried out by manual observation and then detection of the injection angle of the injector. This method of staying in manual empirical observation is difficult to meet the current Engine requirements for increasing injection accuracy of injectors
Moreover, there is currently no special equipment on the market to detect the injection angle of the engine injector. The detection by manual experience observation has large errors and low accuracy.

The invention discloses a fuel spray nozzle atomization observation experimental device. The fuel spray nozzle atomization observation experimental device comprises a box, a fuel spray nozzle supporting frame, a fuel spray nozzle, a vacuum pump, a high-speed shooting device, an atomization liquid pipe and a light supplementing mechanism. A front panel of the box is provided with a door with an observation window. The high-speed shooting device is arranged in front of the box. A rear panel of the box is provided with a vacuum pumping port which is connected with the external vacuum pump throughan air pipe. The fuel spray nozzle supporting frame comprises supports, a support platform and a fixed bracket. The two ends of the support platform are fixedly connected with the supports. The middle of the support platform is provided with a through hole I. The fixed bracket is arranged on the support platform. The fuel spray nozzle is vertically arranged on the support platform. The upper portion of the fuel spray nozzle is fixed through the fixed bracket. One end of the atomization liquid pipe is connected with the fuel spray nozzle, and the other end of the atomization liquid pipe penetrates out of the box to be connected with a fuel spray nozzle comprehensive flow measuring instrument. The light supplementing mechanism is arranged in the box and used for supplementing light requiredfor shooting. The fuel spray nozzle atomization observation experimental device is simple in structure, convenient to operate and capable of conducting vacuum pumping treatment on the interior of thebox. The fuel spray nozzle atomization observation experimental device can be used for studying the oil spray atomization shape, the spray angle and fuel spray distance without air resistance under the negative pressure.
Description
technical field [0001] The invention belongs to the technical field of measuring performance parameters of fuel injectors, and in particular relates to an experimental device for atomization observation of fuel injectors. Background technique [0002] In various industrial systems and the automobile industry, fuel injectors for internal combustion engines are more common. There are fuel injectors on the fuel injectors. The fuel injectors receive the fuel injection pulse signals from the car and will accurately control the fuel injection volume. The fuel injector is a precision device with very high machining accuracy. At present, the detection of the atomization shape, injection angle, and injection distance of the fuel injector has been carried out by manual observation and then detection of the injection angle of the injector. This method of staying in manual empirical observation is difficult to meet the current Engines place increasing demands on injectors for ever-incr...
