Abstract: A method of simultaneously manufacturing a plurality of crankshafts includes positioning a core system having a plurality of individual cores within a cavity of a mold having first and second halves forming an exterior shape of the crankshafts. The crankshafts' exterior shape includes a plurality of pin bearing journals and a plurality of main bearing journals. Each of the cores passes through each of the crankshafts. At least one core passes through at least one of the pin bearing journals and at least one other core passes through at least one of the main bearing journals. The method also includes introducing into the cavity molten metal to form the crankshafts. As the metal flows into the cavity and around the plurality of cores, a hollow section extending through at least one of the pin bearing journals and at least one of the main bearing journals of each crankshaft is formed.

Abstract: A crankshaft includes first, second, third, and fourth main journals, each coaxially disposed along a crankshaft axis. A first, second, third, fourth, fifth, and sixth crank pin are each parallel with the crankshaft axis, and radially offset from the crankshaft axis. A first crank arm includes a first counterweight, and connects the first main journal and the first crank pin. A third crank arm includes a second counterweight, and connects the second crank pin and the second main journal. A seventh crank arm includes a third counterweight, and connects the third main journal and the fifth crank pin. A ninth crank arm includes a fourth counterweight, and connects the sixth crank pin and the fourth main journal. The first, second, third, and fourth counterweights are the only counterweights of the crankshaft.

Abstract: A method of simultaneously manufacturing a plurality of crankshafts includes positioning a single core within a cavity of a mold having a first half and a second half together forming an exterior shape of the plurality of crankshafts. The exterior shape of each of the plurality of crankshafts produced thereby includes a plurality of pin bearing journals and a plurality of main bearing journals. The method also includes introducing via a mechanism into the cavity a molten metal to form the plurality of crankshafts. As the molten metal flows into the cavity and around the single core, a hollow section extending through at least one of the plurality of pin bearing journals and at least one of the plurality of main bearing journals of each of the plurality of crankshafts is formed. A system for simultaneously manufacturing a plurality of reduced mass crankshafts using the above method is also disclosed.
