Casting core for the cooling jacket of the the crankcase of an internal combustion engine

摘要

The casting core (1) comprises six cylinders (2,2') which form two cylinder rows (10,10') in a V-arrangement. The core supports (3,3') are formed on the ring channels (9,9') of each cylinder row, and are connected to each other by a bridge (4,4'). An axial core support (5) is formed on the main channel between the cylinder rows. The bridge is located outside the crankcase.
