Abstract
An engine block of an engine has an imbalance therein. The engine is balanced by a balance shaft alternator assembly having a balance shaft that rotates synchronously with the crankshaft. The balance shaft is located at an exterior portion of engine block . The balance shaft has a rotor that rotates relative to a stator held in a fixed position relative to engine block and balance shaft . Weights may be applied to the balance shaft alternator assembly on balance shaft or on rotor or a combination of the two. The weights balance an imbalance in the engine to smooth out the operating feel of the engine.
