Abstract
A method is for generating a cylinder crankcase including a foreign object inclusion for cast reduction and for the improved cleanliness of the generated component. The cast material is in particular removed or pushed from the areas between the tie-rods (2) below the water jacket (1), to avoid dirt input into the component during later engine operation. The areas below the water jacket (1) between the tie-rods (2) are designed as a separate tie-rod core (3), and the bolts (4) used during later installation at the water jacket core (5) are enclosed in the tie-rod core (3), so that the tie-rod core (3) is completely surrounded by cast material in the component following the cast and the bolt (4) has coalesced with the cast, and the tie-rod core (3) remains in the generated component and is located in an encapsulated space generated by the cast material.
