Abstract

PURPOSE:To reduce lateral pressure on both side walls which are smoothly continuous to both the arc-shaped end walls of a piston of elliptic cross section for an internal combustion engine and extend in the direction of the major axis of the elliptic cross section, by curving the lower portions of the side walls inwards. CONSTITUTION:A piston 3 of elliptic cross section for an internal combustion engine comprises both arc-shaped and walls 4, 4 located at the ends of the major axis l-l of the elliptic cross section and both nearly flat side walls 5, 5 located at the ends of the minor axis s-s of the elliptic cross section. The outside surfaces of the side walls 5, 5 below the lowest ring groove 8 is recessed at (b). The side walls 5, 5 are deflected in proportion to lateral pressure F so that the pressure reception area of each side wall 5 is increased. For that reason, the pressure on the surface of the side wall 5 is prevented from locally rising.
