Abstract
A combustion engine has at least one balancer shaft, driven by the engine and arranged parallel to the crankshaft, to dampen engine vibrations. The balancer shaft is arranged in a separate housing, mounted on the outside of the cylinder block, to make it possible, with only minor modifications, to equip existing older engine types with balancer shafts. The housing has at least two axially-spaced bearings for the balancer shaft and is attached directly to the engine block by means of fasteners located in the area of those bearings.
