The motion of the control piston is measured while performing injection rate investigations using a purpose-built injection rate analyzer of the Bosch type.

In contrast to the steady rise observed in a similar study, the motion of the control piston in this case is characterized by a changing gradient in the upward movement. The magnitude of the negative displacement of the upper part of the control piston due to the fuel pressure in the control volume corresponds to simulation results of the elastic deformation. Pressure before the inlet connector and pressure in the feed line exhibit a similar course with a difference in magnitude that is rising with higher rail pressures. Precisely with the end of injection the pressure in the feed line surpasses the pressure before the inlet connector for a short moment. The measurement results of control piston motion and pressure inside the injector are of particular interest because these parameters are to serve as indicators for changes in the injection rate caused by phenomena like wear and coking amongst others.The authors thank the German Research Foundation DFG for the funding of the project (reference number WA 2468/4-1) in which the here presented results originated. Furthermore, the authors thank Martin Niedermeier for the development the injector and Mario Meinhardt for the development of the data acquisition.Editorial Universitat Politècnica de ValènciaDeutsche ForschungsgemeinschaftRepositorio Institucional de la Universitat Politècnica de València Riunet20172017-07-28book parthttp://purl.org/coar/resource_type/c_3248VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/bookPartapplication/pdfhttps://riunet.upv.es/handle/10251/100356reponame:RiuNet.
