Abstract (en)
[origin: WO2006117060A1] The invention relates to a reciprocating piston internal combustion engine comprising at least one cylinder (1) which is arranged in such a way that it is back and forth movable, a first crankshaft (4) and a second crankshaft (6), wherein said crankshafts (4, 6) are engageable with each other by means of synchronisation toothed wheels (42, 62) and are placed in at least one common bearing block (7; 107; 207), said bearing block (7; 107; 207) is made of a material exhibiting a first thermal expansion coefficient, said synchronisation toothed wheels (42, 62) are made of a material exhibiting a second thermal expansion coefficient, the sizes of the bearing block (7; 107; 207) and synchronisation toothed wheels (42, 62) in the radial direction and the first and second thermal expansion coefficients are mutually agreed in such a way that the thermal expansion of the bearing block (7; 107; 207) between two axes of rotation (X, X") is substantially identical to the thermal expansion of the synchronisation toothed wheels (42, 62).
