In this work, atomization parameters were analyzed by the image visualization of spray from a multi-hole direct injection injector, operating in a backpressure chamber. Such characteristics like cone angle and penetration were analyzed for similar fluids concerning gasoline and ethanol - EXXSOL D40 and EXXSOL D60 respectively under an environment pressure of 5 bar, to simulate incylinder condition, and injection pressure of 70, 90, 100 and 110 bar. To control the injection a Motec-M84 and a driver peak and hold were used. A high speed camera was used for recording images of injection process. The spray images were obtained by a 6504 frames per second recording process, applying shadowgraph technique and MatLab codes were written for image treatment. With the data generated, a comparison between the fluid parameters could be made for direct injection under pressurized environment.
