Optical analysis of diesel sprays
1996 (Engelska)Konferensbidrag, Publicerat paper (Övrigt vetenskapligt)
Abstract [en]

An injection test rig suitable for optical analysis of diesel fuel injections in a constant volume pressurized vessel has been developed. Optical access to the vessel is obtained with two quartz glasses. The injection system is based upon an electronically controlled injector with an internal hydraulic pressure booster. The injection system has been tested at a temperature of 300 K and a peak injection pressure of 98 MPa. The gas pressure in the vessel was varied between 100 kPa and 4 MPa. The entire system is controlled by a computer. The spray is backlighted with a flashlight. A long distance microscope magnifies the image of the injection. The magnification is continuously variable between unity and 50 times magnification. The resolution of the system is approximately 5 µm when using the largest magnification. The pictures were analyzed using commercially available software.
