ABSTRACT:
A control system for the fuel system of an engine which has electrically operated valves which control the quantity of fuel supplied to the combustion chambers of an engine includes a disablement controller which in a test situation can operate to prevent the supply of fuel to the combustion chambers in turn. The system also includes a comparator which observes the variation of an engine operating parameter e.g. fuel level during the test and trim circuit which acts to modify the amount of fuel supplied to the individual combustion chambers on the basis of signals provided by the comparator, so that each combustion chamber contributes substantially equally to the power output of the engine.
