Abstract
A system for controlling the operation of one or more fuel injectors includes a microcontroller, a pre-driver unit, and a power unit. The system is connectable to an electrically actuated fuel injector via at least two wires from the power unit, wherein the pre-driver unit is located between the microcontroller and the power stage, and wherein the microcontroller unit is adapted to send data to the pre-driver unit. The pre-driver unit is adapted to receive the data and control the power stage dependent on the data such that the power stage is adapted to output a corresponding signal along the wires to the fuel injector. The data includes both injector activation pulse data and other auxiliary data for the injectors.
