Abstract
An engine counterbalancing system has a counterbalance weight that reciprocates in a linear manner in opposition to piston movement. The counterbalance weight is preferably coupled to the crankshaft via two spaced link arms that engage two respective eccentrics of the crankshaft. The counterbalance weight is guided by one or more rails that are formed integrally on the inner surface of the crankcase housing.
