Abstract (en)

[origin: DE19943001C1] The cylinder head for a water-cooled internal combustion motor has a flow unit (19) for additional coolant water in the coolant channel (15). It gives a targeted coolant water flow and cooling at the hot spot (17) at the wall (18) of the cylinder head (2). The flow unit (19) has one or more additional channels (20) to give the coolant flow pattern at the hot spot (17).

Abstract (de)

Dieser Zylinderkopf umfaßt an einer Wand des Zylinderkopfs wenigstens eine durch Strahlwärme eines Brennraums hervorgerufene Heißstelle. Besagte Heißstelle wird mittels einem von Kühlwasser durchströmten Kühlkanal gekühlt. Zur Optimierung der Kühlung der Heißstelle sind im Kühlkanal zusätzliche Kühlwasser führende Strömungsvorkehrungen für eine gezielte Kühlwasserströmung und Kühlung der Heißstelle an der Wand des Zylinderkopfs vorgesehen.
