Embodiment Construction

[0029] At the outset, it should be pointed out that the same reference symbols or the same component designations are used for the same parts in different embodiments, wherein the disclosure content contained in the entire description can be transferred to the components with the same reference symbols or the same component designations. on the same part. Likewise, the positional information selected in the description, such as above, below, sideways, etc., refers to the directly described and illustrated figure and in the event of a position change, the positional information is transferred to the new position.

[0030] figure 1 A section through the internal combustion engine 1 along the axis 2 of the crankshaft 3 is shown. The internal combustion engine 1 partially shown in this figure has an engine housing 4 with a cylinder head unit 5 and a cylinder block 6 . Furthermore, at least one piston 7 and a crankshaft 3 are accommodated in the engine housing 4 . The illustrate...

Abstract

The invention relates to an engine housing (4) with a cylinder block (6) and a cylinder head unit (5) comprising a head portion (8) and at least one integrally cast cylinder portion (9) with an internally lying piston bearing surface (11). The cylinder portion (9) of the cylinder head unit (5) can be pushed at least partially in the axial direction of the cylinder portion (12) into the cylinder block (6). The cylinder head unit (5) can also be clamped in the axial direction of the cylinder portion (12) against the cylinder block (6) by means of at least one fixing element (23).

Description

technical field [0001] The invention relates to a motor casing for an internal combustion engine, and to an internal combustion engine equipped with the same, as given in claims 1 and 16 . Background technique [0002] US Pat. No. 4,708,105 A discloses an internal combustion engine in one-piece embodiment, in which at least one hollow cylinder with an inner bearing surface for the piston is embodied together with at least one cylinder head as a one-piece casting or is formed as an integrated Cylinder head unit. The engine or cylinder block of the internal combustion engine is divided in a vertical plane along the rows of cylinders, whereby the cylinder block is formed from two half shells with a vertical separating or joining plane. The half shells are dimensioned such that the upper part section of the cylinder block which supports or partially accommodates the cylinder head unit and the lower part section of the cylinder block which forms the crankcase respectively pass t...
