ABSTRACT:
A cylinder head having a device for returning lubricating oil from the interior is provided with two separate collectors which each extend in the longitudinal direction of the cylinder head. One of the collectors is connected with the interior of the cylinder head in the forward or rearward area of the cylinder head. The other of the collectors is connected with the interior only in the opposite rearward or forward area of the cylinder head. As a result, it is ensured that, in each case, at least one of the two collectors in the area of their connection point into the interior, also in the event of strong decelerations/accelerations, is always below the adjusting oil level and thus a disposal of oil from the cylinder head is ensured under all operating conditions.
