ABSTRACT:
A vibration reducing system for an engine is disclosed. The vibration reducing system includes at least one pumping member movable through a plurality of pumping strokes during an engine cycle. The vibration reducing system also includes a controller in communication with the at least one pumping member, the controller being configured to identify a vibration characteristic of the engine. The controller also is configured to adjust the displacement of fuel during at least one of the plurality of pumping strokes based on the vibration characteristic.
