Abstract

The invention relates to a mass compensator for an internal combustion piston engine with three banks of four cylinders and a crankshaft with four crank pins on each of which operates one connecting rod of each bank of cylinders, whereby to compensate the especially second-order mass forces and moments, compensating shafts bearing balance weights are fitted which are driven in opposite directions at twice the crankshaft speed and whose axis of rotation co-ordinates to the crankshaft axis substantially meet the conditions below: EQU y.sub.2 =-2y.sub.1 and x.sub.2 ==2x.sub.1.
