Abstract
A fuel system for an internal combustion engine includes a pump/injector having an actuating winding to which power is supplied by a first electronic means. A first control signal is supplied by a second electronic means to energize the winding and a second control signal is supplied by a third electronic means to de-energize the winding. The third electronic means calculates the time at which the winding should be de-energized to allow the piston in the pump to draw in the required volume of fuel, the second electronic means causing delivery of fuel when the required volume of fuel has been drawn into the pumping chamber of the pump.
