Abstract: A crankshaft having a front end, a rear end, and a central axis extending from the front end to the rear end is provided. The crankshaft includes a front crankpin, a rear crankpin, and one or more central crankpins. The front crankpin is located in proximity to the front end and the rear crankpin is located in proximity to the rear end. Further, the one or more central crankpins are located substantially equidistant from the front crank pin and the rear crankpin. The crankshaft further includes pairs of counterweights disposed on each side of the front crankpin, the rear crankpin and the one or more central crankpin. The counterweights are disposed such that counterweights in each pair of counterweights are angularly offset with respect to each other

Abstract: A crankshaft having a crankpin journal, a main journal joined to the crankpin journal by a crank web, is provided. The crankpin journal and the main journal have a hardened surface upto a first pre-determined depth. The crankshaft further includes a crankpin journal fillet joining the crankpin journal and the crank web. The crankpin journal fillet includes a hardened surface strengthened by a peening process. The crankshaft further includes a main journal fillet joining the main journal and the crank web. The main journal fillet includes a hardened surface strengthened by the peening process. The crankshaft also includes an oil passage extending through the crankpin journal and the main journal. The oil passage extends such that a portion of a surface proximate to the oil passage is hardened to a second pre-determined depth.
