Abstract
Methods and systems are provided for vehicle direct injection fuel pump control. In one example, a method may include reducing a flow speed of fuel from a cam-driven direct injection fuel pump for at least half of a total duration of an output stroke of the fuel pump. A cam driving the fuel pump may reduce the flow speed at a first rate during a main portion of the output stroke, and the cam may reduce the flow speed at a second rate during an end ramp portion of the output stroke.
