Abstract

The invention relates to a cylinder head (1) of an internal combustion engine with a camshaft bearing mechanism (2) situated thereon in which a hollow camshaft (3) is rotatably mounted, forming an outlet for discharging blow-by gases laden with oil droplets out of the crankcase and is designed as an oil droplet separator for separating the oil content out of these gases. The camshaft (3) passes through a valve space (11). A rocker cover (13) or a multichannel device (27) is connected axially to at least one end of the camshaft (3), forming an axial gap (9), each having a channel (10) connected coaxially to the hollow space (5) of the camshaft (3) so that blow-by gases from which the oil has been removed can be discharged from the camshaft (3), and each being designed so that they either form an oil collecting space (12) that is sealed with respect to the valve space (11) or they introduce oil that has been separated into such an oil collecting space (12).
