Abstract
The invention concerns an internal combustion engine and a method of producing the engine in which the engine has at least one cylinder and with a crank drive comprising a crankshaft, in which the crankshaft mounted in the crankcase has an associated crankshaft throw, the crankshaft throws being arranged spaced apart along the longitudinal axis of the crankshaft, and at least one compensation weight serving as imbalance is arranged on the crankshaft on the side opposite at least one crankshaft throw. The compensation weight has an arcuate form on the outward-facing side, the outside of which running in the peripheral direction has a constant distance S from a reference axis which runs parallel to and spaced by a distance Δ from the longitudinal axis of the crankshaft, wherein the reference axis is arranged on the side facing away from the compensation weight, starting from the longitudinal axis of the crankshaft.
