1. Internal combustion engine with a cylinder crank case (2) and a light alloy cylinder head (1) which is connected to the cylinder crank case by bolts (9) which extend through a bore (10) in the cylinder head and are screwed into a tapped hole (11) in the cylinder crank case, whereby a bushing (15) of a material harder than the material of the cylinder head (1) is arranged in the bore (10), the outer end face (17) of which bushing forms the bearing surface for the head (12) or the nut of the cylinder head bolt (9), characterized in that the bore (10) in the cylinder head (1) comprises an internal thread (14) and that the bushing (15) is a threaded bushing and is screwed into the internal thread (14) and is supported axially on the cylinder head (1) through its external thread in such way that the screw force is transmitted to the cylinder crank case (2) through the bushing (15), the thread (14) and the cylinder head (1). |
