摘要： The present invention is related to an internal combustion engine 100, a method for running an internal combustion engine 100 and a crosshead pin 11. The internal combustion engine (100) with at least one cylinder (1) has at least one piston (6) which is movably arranged within the cylinder. The engine has a rotatably arranged crankshaft (2), with the piston (6) being connected to a crosshead (8) via a piston rod (7), and with a crosshead pin (11) connected to the piston rod (7), and with the crosshead (8) being connected to the crankshaft (2) via a connecting rod (9) to drive the crankshaft (2). The engine comprises a variable compression ratio device (10) for changing a compression ratio of an engine, which is provided with a fluid chamber (12) arranged in the inside of the crosshead pin (11), in which the piston rod is moveable relative to a bottom (13) of the fluid chamber (12) by a pressure-increased working fluid being supplied into the fluid chamber (12). The piston rod (7) comprises cooling channels (14a, 14b). The crosshead pin (11) comprises at least one first flow path (15) for guiding a cooling fluid that is to be supplied to at least one of the cooling channels (14a) and at least one second flow path (16) for guiding a cooling fluid that is to be discharged from at least one of the cooling channels (14b). The first flow path (15) is arranged in a first distance (d1) to a bottom plane (17) defined by the bottom (13) of the fluid chamber (12) and the second flow path (16) is arranged in second distance (d2) to the bottom plane (17). The first distance (d1) is smaller than the second distance (d2). The first flow path (15) comprises a plurality of first channels (18), preferably uniformly, arranged in a first cross-section (19) of the crosshead pin (11) parallel to the bottom plane (17) .

摘要： A bearing bushing for a connecting rod and a combination of a connecting rod and a bearing bushing are provided. The connecting rod has a small end which includes a bearing bore. A first region of the bearing bore, which in operation is subjected to compressive loading, is longer than a second region of the bearing bore which is subjected to tensile loading. In order to modify a bearing bushing and a connecting rod so that with simple production and optimized weight the connecting rod has good bearing properties for the piston pin, the bearing bushing already has, before insertion thereof into the bearing bore, a shape adapted to the end edge contour of the bearing bore, wherein the first region of the bearing bushing is likewise longer than the second region thereof. A method of producing such a small end is also disclosed.
