ABSTRACT:
A fuel control system (10 or 70) includes a hydraulic servo system (17) for moving a fuel rack (15) in response to movement of a rack control member (16). A brushless direct current torque motor (50), having a rotor (51) and a control lever (53) fixed thereto, is arranged with its lever end (54) confined between opposed shoulders (41, 42) on the rack control member (16). Electronically energized movement of the rotor (51) and its control lever (53) in one direction, or spring (56) biased movement in the other, causes corresponding movement of the control member (16) and fuel rack (15). A second control lever (99), movable by a mechanical governor control (80), is engageable with another shoulder (104) on the rack control member (16) to move it in a fuel-decreasing direction. The present fuel control systems (10 and 70) are particularly useful in conjunction with a fuel injection pump (11) for a diesel engine (13) with the fuel flow rate being controlled in sole response (10) to an electronic engine control (60) or in dual response (70) to an electronic engine control (60) and a mechanical governor control (80).
