Abstract: In the following, a camshaft arrangement will be described. In accordance with one example of the present invention, the camshaft arrangement has a camshaft housing, a camshaft arranged in the camshaft housing that has at least one first cam, as well as a second cam that is larger than the at least one first cam and that is rigidly connected with the camshaft. In addition, the camshaft arrangement has a drive wheel that is rigidly mechanically connected with the second cam or with the camshaft, as well as a slide bearing that is arranged coaxially between the drive wheel and the second cam. A bearing bush of the slide bearing is arranged in the camshaft housing or in a bearing cover that is mounted on the camshaft housing. The second cam or the drive wheel or a nut screwed on the camshaft has a running surface for the slide bearing.

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).
