    Abstract: Abstract of DisclosureA main bearing cap (20) for an internal combustion engine consists of an aluminum alloy with an iron alloy core (10). The cap has a supporting surface (22) for a bearing shell. The iron alloy core has a central portion (13) with two spaced apart through-channels (15) filled with an aluminum alloy (24) forming a coherent mass with an aluminum layer (23) the outer limiting surface of which forms the supporting surface (22).

    Abstract: Abstract of DisclosureA method of high pressure die casting in iron alloy reinforcements for main bearing scantlings in an aluminum alloy engine block for an internal combustion engine. Prior to casting, reinforcements (1) having bores (6) for main bearing screws are placed in a die cavity (21), so that cores for main bearing screws protrude into the bores in each reinforcement on one side of the reinforcement. Then the reinforcements are fixed in the die cavity by placing a cylinder liner core (25) against a surface (27) of the reinforcement on the opposite side of the reinforcement.
