ABSTRACT:
The internal combustion engine has, arranged in pairs, cylinders offset in angle in relation to one another in the direction of the axis of rotation of its crankshaft. The engine block consists of two castings, each of which combines integrally in one piece with one another one half of a crankcase, one of the cylinder housings of each pair and the cylinder heads. The castings are symmetrical in rotation at 180.degree. in relation to an axis of symmetry lying in the plane of separation of the crankcase perpendicularly of the axis of rotation of the crankshaft, so that they can be manufactured in one and the same casting mold. The cranks for the crankshaft which are allocated to each piston pair are connected with one another through a cranked middle piece, to reduce the distance between the cylinder axes and thus to reduce vibration.
