Abstract
A dual-lobed cam for a camshaft of an internal combustion engine is presented herein. The camshaft includes an elongated shaft rotationally disposed in relation to a crankshaft via a timing assembly. The dual-lobed cam includes an enlarged base circle region circumferentially disposed around the camshaft, with two oppositely disposed lobes extending therefrom. The lobes define lift regions off of the base circle which drivingly engage a valve assembly. The camshaft disclosed herein may include a rotational speed of one-fourth the rotational speed of a crankshaft or crankshaft sprocket, thereby preserving power and increasing efficiency of the overall engine.
