摘要： The invention relates to a cylinder bore (10, 110) with a cylinder running surface (14, 114) for a cylinder housing of an internal combustion engine. An upper reversal point (OS) and a lower reversal point (US) are defined in the cylinder bore (10, 110). A piston (20) which is moved up and down in the cylinder bore (10, 110) and has piston rings (21) and a piston shaft (22) reaches a speed (V
0 ) which is almost zero at the reversal points when the motor is being operated, and the piston (20) reaches a maximum speed (V
max ) in a region (15, 115) between the upper reversal point (OS) and the lower reversal point (US) when the motor is being operated. The invention is characterized in that at least two circumferential depressions (18a, 18b; 118a, 118b, 118c) are formed within the region (15, 115), and the diameter (D2a, D2b, D2c) of the depressions is greater than the diameter (D1) of the cylinder bore (10, 110) above the region (15, 115) and greater than the diameter (D3) below the region (15, 115).

摘要： A mold assembly for forming a piston and method of molding a piston therewith includes a pair of mold halves moveable toward and away from one another along a linear path that is substantially perpendicular to a longitudinal cenntral axis of the piston between an engaged position to provide at least a portion of a mold cavity for forming an outer periphery of the piston and a disengaged position to allow extraction of the piston from the mold cavity. The assembly also has a pair of cooling gallery mandrels moveable along a linear path into an engaged position between the pair of mold halves to form an undercut cooling gallery of the piston. The pair of cooling gallery mandrels are movable to a disengaged position to allow extraction of the piston vertically along the axis.
