Abstract (en)

[origin: EP0819837A1] The engine has a cast cylinder block (3,4) with a cooling water jacket (10), and a cylinder head (7) with cooling water channels (11), defining a common flange surface between the cylinder head and the cylinder block. There are cooling water feeds (16,20,28,29) within the cylinder block, formed as forward feed and return feed channels. At least one cooling water feed issues in the flange surface. Between the cooling water cover and at least one of the cooling water feeds a connection in the form of a slot extends from the flange surface into the cylinder block. The depth of the slot (T) is greater than its width. The slot runs somewhat radially to a cylinder.
