Beschreibung
Zusammenfassung:	Producing a cylinder housing (10) for an internal combustion engine of a motor vehicle, comprises producing at least two cylinders (12) which are separated by a cylindrical web (14), and a cooling jacket. The cooling jacket at least partially covers the two cylinders. A laser drilling device is led through corresponding through holes of a cylinder cover surface (22) of the cylinder housing. At least one web cooling channel extends through cylindrical web, is drilled parallelly to the cylinder cover surface in the cylindrical web by means of the laser drilling device. Die Erfindung betrifft ein Verfahren zum Herstellen eines Zylindergehäuses (10) für einen Verbrennungsmotor eines Kraftwagens, bei welchem wenigstens zwei durch einen Zylindersteg (14) voneinander begrenzte Zylinder (12) sowie ein zumindest teilweise die beiden Zylinder (12) umgebender Kühlmantel hergestellt werden, wobei eine Laserbohrvorrichtung durch entsprechende Durchgangsöffnungen (20) einer Zylinderdeckfläche (22) des Zylindergehäuses (10) geführt und zumindest eine durch den Zylindersteg (14) verlaufende Stegkühlbohrung (24) mittels der Laserbohrvorrichtung im Wesentlichen parallel zu der Zylinderdeckfläche (22) in den Zylindersteg (14) gebohrt wird.
