- the flange plates 5 preferably pass obliquely Achieving a stiffer connection between the respective cylinder 6 and Flange plate 5 against operating vibrations, which are additionally spaced in series Cylinders 6 between bridges 23 arranged in the row direction between the cylinders 6 are reduced.
- the cylinders 6 are without casting an additional Material free in the respective coolant.
- the flange plates 5 For a permanent connection of the engine block 3 with the one-piece casing 4 have the flange plates 5 in the machine longitudinal and transverse directions in each case by means of large radii cambered edges 24 on the machine housing corners merge into other, smaller radii. They are further Edges 24 e.g. designed as T-shaped flanges 25 in cross section. Alternatively to the Flanges 25, the edges 24 can also have a rough surface for positive and non-positive connection with the light metal casing 4. Furthermore, the flanges 25 can also have a rough surface.
- the engine block can 3 one made of outer and inner longitudinal and front housing walls assigned one-piece casing 4 from a light metal casting be, which when cooling in the shrinking through the flange 5 of the Engine block 3 handicapped light metal casing 4 over the convex Edges 24 uniformly form-fit and non-positively with the flanges 25 of the Flange plates 5 is connected liquid-tight.
- the casing 4 is further advantageously stiffened in that the Flange plates 5 cylinders 6 integrally connected by a material fit, each in one with coolant openings 26 provided cold room cover plate 27 which with the casing 4 in one-piece material connection.
- connection points 34 for ancillaries and / or support brackets via adjacent hollow struts 13 arranged pins 35 are connected preferably serve the arrangement of screw points.
