  • Selective displacement control of multi-plunger fuel pump
    Patent number: 8136508
    Abstract: A pump for a combustion engine is disclosed. The pump may have at least one pumping member movable through a plurality of displacement strokes during a single engine cycle. The pump may also have a controller in communication with the pumping member. The controller may be configured to selectively reduce an amount of fluid displaced during at least one, but less than all of the plurality of displacement strokes. The reduction may be initiated in response to a demand for the displaced fluid.
