<p>A method of controlling an electrically/electronically operated actuator for a fuel system or component thereof, wherein in operation said actuator is supplied with electrical pulses, and wherein for each actuation cycle, said actuator is supplied with at least one pulse of duration Tend comprising: determining the time Tp taken for the current through the actuator to achieve a threshold value, and varying the pulse duration Tend dependent on the value Tp. The actuator may be a solenoid operated valve, e.g. of a fuel injector.</p> |
