eated cylinder air. The data in Figure 8 show that large decreases in the volumes of similar sprays occur with increased gas densities. Since the density of the gas in an engine cylinder is proportional to the compression ratio, the volume growth of a fuel spray in an engine cylinder will depend… … Fig. 4.—Effect of fuel on spray characteristics. Injection pressure, 8,000 pounds per square inch. Chamber pressure, 200 pounds per square inch. Orifice diameter, 0.022 inch. Ratio of orifice length to orifice diameter, 2. Ratio of orifice area to groove area, 0.63 V= 1.85-2.0 log10 D. (Injection…
