Abstract
A system for controlling a fuel injector in accordance with an injection control strategy for an engine includes programmable control logic to provide selectable threshold signals for comparator circuits and/or control logic configured to receive various control signals in the control circuit and determine one or more timing signals. The programmable control logic allows the drive circuit to be modified, without changing any hardware, to accommodate injectors having different characteristics and to change the pulse modulation strategy. The control logic that receives the control signals produces injection timing signals to allow enhanced monitoring and control over the fuel is injection process.
