ABSTRACT:
A fuel system for an internal combustion engine (10) includes a controller (14) which controls the operation of an engine fuel pump (13). Signals are supplied to the controller by a transducer (16) which is responsive to the passage of teeth formed on the periphery of a wheel (12) which is mounted on the engine crankshaft. In order to generate an engine speed signal it is necessary to know the tooth spacing errors and these are determined by recording two time pulse sequences of signals from the transducer at different engine speeds and loads and then processing those signals to firstly determine the periodic component of the signals due to the fluctuation of engine speed which occurs due to the individual power strokes of the engine.
