Abstract (en)

[origin: WO2007085738A1] The invention relates to a crankshaft (9) for a variable compression ratio engine, which can be used to convert the reciprocating motion of the main moving components (2, 3, 5, 6, 40) of the variable compression ratio engine into rotational motion. The inventive device, which includes hydrodynamic bearings, has no balance weights.
