Abstract

A fuel system for an engine, particularly a compression-ignition engine, has a pump supplying fuel to the engine and a control member for determining the output of the pump, the control member being itself controlled by a control circuit receiving parameters one of which is measured by transducer means. The transducer means is designed so that if it fails, the fuel system fails safe. In another arrangement, in which failure of the transducer means results in an output which would increase fuel, then the failure is detected and action is taken.
