−−−−バランスウエイト。Figure 1 is a vertical cross-sectional view of a conventional piston with an eccentric combustion chamber, A is without a balance weight, B is with a balance weight, and Figure 2 is the relationship between the forces acting on the piston during the compression stroke at idle. Figure 3 shows the relationship between piston inertia force and rotational moment, where A shows the case where the inertia force acts downward, B shows the case where the inertia force acts upward, and Fig. 4 shows the relationship between the piston inertia force and rotational moment. FIG. 5 is a longitudinal sectional view of a piston with an eccentric combustion chamber showing one embodiment, and FIG. 5 is a bottom view of the same piston. 11...Zeston crown part, 12...Eccentric combustion chamber, 15...Piston skirt part, 16--
