Multi-cylinder reciprocating piston internal combustion engine, has crankshaft relocatable towards rotation axis, and piston rod rotatably supported in bearing pin of piston, where pin axis is arranged parallel to rotation axis

摘要

The engine has a crankshaft (1) rotatable around a rotation axis (4), and a piston rod rotatably supported in a piston rod pin (2) of the crankshaft. A reciprocating piston is connected with the piston rod and located in a cylinder housing. A bearing axis (5) of the pin is arranged inclined to the axis. The crankshaft is relocatable towards the axis, and the piston rod is rotatably supported in a bearing pin of the reciprocating piston. A pin axis of the bearing pin is arranged parallel to the rotation axis.
