Wright, D O

A low voltage supply control system is described for fuel injectors in a fuel injection system, the system comprising: a source of power; at least one electromagnetic fuel injector; means for calculating the operating time of at least one electromagnetic fuel injector, the means responsive to the magnitude of the source of power for generating a pulse-width operating signal; injector driver means responsive to the pulse-width operating signal for energizing the at least one electromagnetic fuel injector; means for comparing the magnitude of the source of power with a predetermined magnitude value and generating a control signal when the magnitude of the source of power is less than the predetermined magnitude value; and voltage supply means responsive to the control signal for substantially doubling the magnitude of the source of power to the injector drive means, the voltage supply means comprises an input logic state, a power stage, a storage capacitor and a coupling diode for connecting the injector driver means to the source of power.
