Cylinder head of an internal combustion engine
Abstract:
A cylinder head of an internal combustion engine with several cylinders includes an inlet side and an outlet side with at least two outlet channels per cylinder, wherein a first coolant jacket is arranged in the cylinder head, the first coolant jacket including a first coolant collection channel which extends along the cylinder head on the outlet side over the outlet channels. The first coolant collection channel is connected to cooling chambers at least partially surrounding the outlet channels, the cooling chambers being in a fluidic connection with at least one transfer opening in a cylinder head gasket plane, wherein one first transfer opening per cylinder is arranged in a first transverse engine plane containing a cylinder axis, and wherein a first transverse cooling passage extends from each first transfer opening in the first transverse engine plane between two respective outlet channels, the first transverse cooling passage splitting into two cooling sub-passages in the area of the cylinder axis. Each cooling sub-passage respectively surrounds an outlet channel in the area of a respective outlet opening over an angle (α) of approximately 180° and each cooling sub-passage is connected to the coolant collection channel by means of a second transverse cooling passage, wherein each second transverse cooling passage is arranged in the area of a second transverse engine plane extending through at least one cylinder head bolt bore.
