Abstract
An engine fuel system including a solenoid actuated fuel control valve (16) which is energized to cause fuel delivery to the associated engine. The valve is initially closed to achieve pilot delivery of fuel by a high current pulse supplied to the solenoid winding (7) and is then allowed to open under the influence of a spring, the opening movement of the valve member being controlled by supplying current to the solenoid winding. Finally by supplying further current to the winding the valve member is closed to achieve closure of the valve for the main delivery of fuel.
