Abstract
A V-type engine is provided with a camshaft driven balance shaft assembly that is compactly located in the valley between the banks of cylinders and consists of a pair of coaxially mounted first and second order balance shafts, one within the other, each of which has diametrically opposed counterweights on opposite sides of the center of the shaft that effect rotating moments to cancel residual first order and second order inertial unbalance moments that occur during normal engine operation that have not previously been cancelled by conventional counterweights mounted on the engine crankshaft.
