Fast response two coil solenoid driver

Patent ·
OSTI ID:6735800

A system for energizing a fuel injector of a fuel injected engine having a metering chamber and a two coil solenoid operatively situated thereto for permitting a controlled quantity of fuel to flow therein. The system includes a pulse generator for generating a plurality of timing and fuel metering pulse width signals in synchronism with the combustion process within a cylinder of the engine, a voltage boost circuit responsive to timing and metering pulses and means for transferring, in seriatim energy from the boost circuit to a first low inductance pull-in coil and for energizing a second high inductance hold coil.
