    Abstract: A pumping assembly having a high-pressure pumping stage and an integrated transfer pumping stage. The pumping assembly comprises a cam (104;204) arranged for eccentric rotation about a drive shaft axis (A), a cam rider (106;206), a cam follower (112;212), the cam follower (112;212) having reciprocal movement parallel to a cam follower axis (Q) that is perpendicular to the drive shaft axis (A), a high-pressure pumping head having a high-pressure pumping chamber, and a pumping element driven by the cam follower (112;212). The pumping assembly further comprises a first chamber (150a;250a), inlet means (174;274) for allowing fluid flow into the first chamber (150a;250a), and outlet means (150b,163,166,166a;250b,263,266,266a) for receiving fluid from the first chamber (150a;250a) and for delivering fluid to the high-pressure pumping head. Rotation of the cam (104;204) about the driveshaft axis (A) causes an increase in volume of the first chamber (150a;250a) during a first part of the pumping cycle and a decrease in volume of the first chamber (150a;250a) during a second part of the pumping cycle, so as to effect a transfer pumping of fluid from the inlet means (174;274) to the outlet means (150b,163,166,166a;250b,263,266,266a) for delivery to the high-pressure pumping head.

The pumping assembly comprises drive means comprising a drive plate (114) rotatable about a drive axis (A) and including a recess (120) arranged eccentrically with respect to the drive axis (A); a guide arrangement (122, 122a) received, at least in part, in the recess (120) of the drive plate (114) so that rotary movement of the drive plate (114) gives rise to translatory movement of the guide arrangement (122, 122a); a pumping element (108); and a slide member (112) associated with the pumping element (108). The slide member (112) is in sliding engagement with the guide arrangement (122, 122a) to define at least one sliding interface (196, 198) between the guide arrangement (122, 122a) and the slide member (112), such that rotary movement of the drive plate (114) causes reciprocal linear movement of the pumping element (108) along a pumping axis (Q).

    Abstract: A method of fuel injection, comprising constructing an hydraulic behaviour profile by fuel pressure measurement, using the hydraulic behaviour profile to predict fuel pressure that will prevail in a fuel injector during an injection event, and supplying a control signal to the fuel injector to control the amount of fuel injected during the injection event in accordance with the predicted fuel pressure. By predicting the fuel pressure that will prevail during an injection event, the fuel delivered during the injection event can be accurately controlled.
