Claims

[Scope of utility model registration request]

On the side of the cylinder part that forms the cylinder bore,
In a die-cast cylinder block that forms an oil drop passage and/or a blow-by gas passage that communicates from the joint surface with the cylinder head into the lower crankcase, the crankcase has a connection between the crankcase and the cylinder section. A bulge extending toward the joint surface with the cylinder head is integrally formed on the outer surface of the connecting portion and directly below the oil drop passage or the blow-by gas passage, and the oil drop passage is provided within the bulge. and/or a die-cast cylinder block for an internal combustion engine, characterized in that the lower end of the blow-by gas passage is open.
