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.
