Camshaft assembly

An internal combustion engine, comprising:

• at least one cylinder block that comprises a combustion chamber and at least one adjustable valve for introducing fresh air into the combustion chamber or for discharging exhaust gas out of the combustion chamber,
• a camshaft assembly, the camshaft assembly including:
• a camshaft extending along an axial direction and at least one cam non-rotatably arranged on the camshaft,
• an axial bearing for at least one of an axial alignment and an axial fixing of the camshaft, wherein the at least one cam is part of the axial bearing,
• wherein the axial bearing includes a first axial bearing element and a second axial bearing element that lie opposite one another along the axial direction, and wherein the at least one cam is arranged axially between the first axial bearing element and the second axial bearing element such that the camshaft with the at least one cam can rotate relative to the first axial bearing element and the second axial bearing element about a centre longitudinal axis of the camshaft running in the axial direction,
• wherein the first bearing element and the second bearing element are arranged fixed in place relative to the at least one cylinder block, and
• wherein the at least one cam of the axial bearing is drive-connected to the at least one valve for adjusting the at least one valve.
