室底面の隈部丸み。FIG. 1 is a sectional view of the main part of the combustion chamber of a direct injection diesel engine, and FIG. 2 is a graph of the air distribution in the combustion chamber, where the horizontal axis is the distance r from the center of the combustion chamber, and the vertical axis is the amount of air. Fig. 3 is a comparison diagram of the spray distribution of the conventional type and the inventive type combustion chamber, and Fig. 4 a, b, and c show the spray when the roundness R of the bottom corner of the flank angle α of the combustion chamber is large and when the radius R is small, respectively. Figures 5 and 6 are explanatory diagrams of the influence on the distribution, and Figures 5 and 6 are examples of the present invention, Figure 5 is a plan view of the combustion chamber, and Figure 6 is a diagram showing the effects of Figure 5, o-f, o-d, and o-, respectively. It is an a-line sectional view. 3... Combustion chamber, 5... Injection nozzle, 6... Nozzle port,
S: Swirl, α: Flank angle, R: Rounded corner of the bottom of the combustion chamber.
