Abstract:
A balancer system for a power plant includinga transversely mounted engine having an engine mount located on a first side in a direction of an axis of a crankshaft of said engine, said engine being supported through said engine mount to a vehicle body, anda transmission fastened to said engine at a second side opposite to the first side in the direction of the axis of the crankshaft,said balancer system comprising:a balance shaft which is rotatably installed to said engine;wherein a first distance between a center of gravity of power plant and a center of inertia force generated by the engine is smaller than a second distance between the center of gravity of the power plant and a center of inertia force generated by said balance shaft, each of the first and second distances being on a plane containing the axis of the crankshaft; andwherein an inertia force generated by said balance shaft is determined at a value which reduces vibration to a generally zero level at a support center of said engine mount section.
