Internal combustion engine, has cooling ducts formed by respective bore holes, which are formed in cylinder head sealing surface, where one hole ends in another hole

摘要

The engine has a cooling duct (8) that intersects a longitudinal section of the engine and formed by a borehole (11) arranged for a longitudinal section. Another cooling duct (16) in the area of cylinder bars is formed by another bore hole (15), where the holes are formed in a cylinder head sealing surface (10). The hole (15) connects a coolant opening (9) of the surface with the hole (11), where the hole (15) ends in the hole (11).
