CRANK SHAFT FOR AN INLINE INTERNAL COMBUSTION ENGINE AND AN INLINE INTERNAL COMBUSTION ENGINE

摘要

A crankshaft for an in-line internal combustion engine includes at least two bearing points, and crank throws which include a first and a last crank throw. Each of the crank throws includes a counter-weight element. The first and the last crank throw each additionally include an additional weight. The crank throws are arranged angularly offset with respect to each other so that at least two of the crank throws are arranged in angular coincidence with each other. The crank throws and their respective counter-weight elements are arranged to provide for a mass balance. The first and the last crank throw, as seen in an axial direction of the crankshaft, are arranged in angular coincidence with each other. The additional weight of the first and the last crank throw are arranged in a mirrored manner, as seen in the axial direction of the crankshaft.
