Abstract:
The impinging accuracy of injecting orifice in the engine self-impinging injector is one of the most notable factors affecting engine vibration in engine testing and operotion. Therefore, to precisely measure, analyze and assess the relevant dimension and shape parameters of the injecting hole is very importont for inprovement of the injector reliability in the manufacturing process, such as rings machining, riveting, assembly and welding. With the design of injecting orifice auto-measurement scheme, composition of measurement system, design of special positioning fixture, development of numerical control measurement program, a method to measure the injecting orifice in the engine self-impinging injector was formed eventually. The statistic analysis of the measured data was performed. The result indicates that the measuring method is reliable, and its detection efficiency is increased by about 92%.
