Piston For An Internal Combustion Engine and Production Method Therefore

A piston of an internal combustion engine having a piston head which has a ring zone and is adjoined by a piston skirt which encloses an internal shape, with two box walls which lie opposite one another and are set back with respect to the outer contour of the piston and with two skirt walls which are not set back with respect to the outer contour of the piston, the box walls receiving bosses, the piston skirt having skirt supports which are connected to the boss, characterized in that the width (b) of the box wall is a point of intersection between a pin axis and a continuation with a constant curvature and tangent of the box wall;

• wherein the direction of the skirt support is described by points of intersection (a2i, a3i, a2a, a3a), the points (a2i, a2a) being points of intersection between the continuation with the constant curvature and tangent of the box wall and the outer boss radius (r) which is situated at the level of the pin axis, and the points (a3i, a3a) being the points of intersection between the continuation with the constant curvature and tangent of the box wall and the continuation with a constant tangent of an internal shape;
• wherein the following geometric properties apply to the piston:
• a2i/a3i=from 1.05 to 1.5
• and
• a2a/a3a=from 1.05 to 1.5.
