Abstract (en)
[origin: EP0017328A1] An i.c. engine fuel system includes a main fuel control (19) which controls fuel flow to the engine in accordance with one or more engine parameters. A roughness sensor circuit (11) produces an output related to the roughness of running of the engine and the error between this roughness output and a reference signal is integrated with respect to time by an electronic integrator 15. The output of this integrator (15) is used to modify the fuel flow to reduce the error to zero, by, for example, varying the frequency of a clock (18) which influences the operation of the main fuel control (19).
