Experimental Investigations of the Effects of Electric Control Impulse on Injection Characteristics of Common Rail Type Injector


  • South Ural State University, National Research University, Russia


Background/Objectives: The motor-less fuel stand has been described capturing high-speed video in the process of fuel jet development in Common Rail type injector. Methods: The experiments were carried out simultaneously recording the electric signals of the start and end moments of the electrical impulse controlling the injector with digital color oscilloscope Tektronix TDS-2014С and high-speed imaging of the fuel jet sprays with color video camera FASTCAM SA-X2. Findings: The delays of the start and termination of actual fuel injection that depend on the electrical impulse for the injector control have been determined and the dynamics of the fuel jet development has been observed under the fuel rail pressure from 100 to 165 MPa. The dependency of the duration of the fuel injection process on the duration of the electrical impulse controlling the injector has been established. Applications/Improvements: The results of the study can be used for diesel engine design and commissioning and for improving the shape of the combustion chamber to ensure better carburetion in the cylinder.
