| 摘要 |
The invention relates to a piston (10) for an internal combustion engine, comprising a piston crown (22), a cylindrical piston head (11), which adjoins the piston crown (22), and an at least partially hollow piston skirt (40), which is formed on the piston head (11) on the side facing away from the piston crown (22) and which has two opposite skirt wall segments (50) and two opposite connecting walls (60) that connect the skirt wall segments (50), wherein the connecting walls (60) each have a pin bore (61), wherein the piston head (11) has an annular cooling channel (18), which has at least one inlet opening (28) and at least one outlet opening (30), and the two skirt wall segments (50) widen toward the piston head (11) in such a way that the sector length (L1) of the side of the skirt wall segment (50) formed on the piston head (11) is greater than the sector length (L2) of the side of the skirt wall segment (50) facing away from the piston head (11). |
