FIG. 1 is a plan view showing one embodiment of the metal gasket for internal combustion engines according to this invention;
Figure b is an enlarged view of part A in Figure 1, Figure 2 is a sectional view taken along line - in Figure 1, Figure 3 is a sectional view taken along line - in Figure 1, and Figure 4 is a sectional view taken along line - in Figure 1. A sectional view taken along the line -, Figure 5 is taken along the line - in Figure 1.
6 is a cross-sectional view of a metal gasket without an adjustment plate, and FIG.
Figures 7b and 7c are explanatory diagrams illustrating the correspondence between the force applied to the bead and the spring constant when the bead shapes overlap, and Figure 8 is the load for determining the fluctuating load during the explosion process of an internal combustion engine. The displacement diagrams, Fig. 9a, Fig. 9b, Fig. 9c, and Fig. 9d are diagrams showing, using parameters, the change in the variable load during the explosion process with respect to the size of the spring constant of the gasket. , 10th
The figure shows the varying load per bead peak for the diagram shown in Figure 9b, Figure 11 shows the fluctuation of the spring constant with respect to the tightening load, and Figure 12 shows the magnitude of the spring constant of the gasket. Figure 13 is a graph obtained by calculating the change in the fluctuating load during the explosion process based on the measured values of the components actually used in the internal combustion engine.
