Some Observations on the Liquid Injection Technique as a Research Tool 660748
The liquid injection technique (LIT) is a simple method for observing diesel spray behavior. Excellent visibility of the spray is attained by injecting the fuel into a clear hydrocarbon liquid instead of a pressurized gas. Earlier research with the technique is reviewed, and questions are posed regarding the mechanism of spray visibility in the liquid and the comparability of penetration measurements in liquid and gas. Experimental results lead to the conclusion that visibility in the liquid is due to cavitation and penetrations in a liquid and a dense gas are generally equivalent. Applications of the liquid injection technique to diesel injection problems are briefly discussed from both a research and hardware oriented viewpoint.
