Abstract

PURPOSE:To improve the sealing property of the piston ring and reduce the abrasion loss thereof by forming the piston ring of the internal combustion engine whose cylinder holes and pistons have oval-shaped cross sections so that the pressing force thereof on the surface of the inside wall of the cylinder hole can be increased only at the time of a combustion stroke. CONSTITUTION:The piston ring 13 fitted to the piston having the oval-shaped cross section is formed into an oval shape having circular-arc two end parts 15, 16 in the longitudinal direction and linear two end parts 17, 18 connected smoothly with the former two end parts 15, 16 and is provided with a cut slit 19 at one end part 15. on the occasion, on the outer-peripheral surface 20 of the piston ring 13 are formed the 1st slant surface s1 tilting inside from the intermediate part in the sliding direction thereof toward the lower surface 22 on the side of a crank chamber and the 2nd slant surface s2 tilting inside toward the upper surface 21. The setting is made so that the cross section passing the intersecting point (i) of two slant surfaces s1 and s2 is positioned closer to the side of the upper surface 21 than to the central cross section passing the center between the upper and lower surfaces 21 and 22.
