| Abstrakt: | The flow rate through the holes of the nozzle at constant pressure and steady flow is an important feature of electronically controlled injectors. The flow rates at different pressure of injection determine the main characteristic of Common Rail injectors. In scientific researches it is necessary to determine this flow rate experimentally. This requires specially equipped experimental installations and expensive measuring devices. The article presents a method for determining the steady flow rate through the holes of the nozzles using a standard test bench for Common Rail injectors. The method is based on the assumption that, all else being equal, non-steady phenomena at the beginning and end of the injection and displacement of injection to the control pulse are identical at different injection timing. Under this conditions we can easily determine the steady flow rate through the holes of the nozzle. |
