Abstract:
A fuel pump drive system for engine driving a fuel pump by torque transmitted from a crankshaft via a gear train, comprisinga conventional flywheel housing with a gear through hole opened to a gear train accommodation space and adapted to receive a conventional input gear as an element of the gear train for transmission of the torque to the fuel pump through meshing with an output gear with revolution ratio of an engine to the fuel pump being set to two-to-one, a new input gear in lieu of said conventional input gear for transmission of the torque to the fuel pump through engagement with said output gear via an idle gear within a range of said gear through hole with revolution ratio of the engine to the fuel pump being changed to one-to-one, and an adapter interposed between said flywheel housing and said fuel pump for rotatably supporting said idle gear in a position for meshing with said new input gear.
