Abstract: The invention relates to a method for mounting, in a simple manner, a mass differential gear (4) onto a crank housing (1) of an internal combustion engine. An intermediate gearwheel (9), which can be pivoted about an axis, is arranged between the crankshaft gearwheel (10) and the subsequent drive gearwheel (7), said axis being located on the connection line of the axis of the intermediate gearwheel (9) and the drive gearwheel (7) driven thereby. After fixing the housing (5) of the mass differential gear (4), the intermediate gearwheel (9) is rotated about the axis until zero play is reached between the intermediate gearwheel (9) and the crankshaft gearwheel (10).

Abstract: A cylinder head for a water-cooled, multi-cylinder piston internal combustion engine comprises a lower wall and an upper wall enclosing a cavity. A well extends into the cavity for receiving a fuel injector and/or an ignition device. An intake port and/or an exhaust port extends through the cavity. A cooling-water carrying region comprises areas of the cavity surrounding the well, intake port, and exhaust port. Portions of the cooling-water carrying region are provided with an intermediate web for reinforcing the cylinder head.
