Embodiment Construction
[0046] A combined piston 1 is shown in a cross-sectional view, the left half of the cross-sectional view shows a cross-section of the piston 1 along the longitudinal axis 2 of the piston pin seat hole 3, and the right half shows Piston 1 sectional view staggered 90° with the left half. The piston 1 consists of an upper part 4 and a lower part 5, which are connected to each other by means of a hexagon socket head screw 6 arranged in the middle, so that the hexagon socket 42 of the hexagon socket screw 6 is located inside the piston.
[0047] The upper part 4 and the lower part 5 of the piston 1 are preferably manufactured from forged steel. It is also conceivable to manufacture the upper part 4 from steel and the lower part 5 from aluminum, as well as the upper part 4 from forged steel and the lower part 5 from cast aluminum.
[0048] The cylindrical upper part 4 forms a piston crown 7 in which a rotationally symmetrical combustion chamber 8 is formed. The radially outer surf...
