Abstract:
A fuel injector system comprising:a plurality of fuel injectors; a control for driving said fuel injectors; an electrical component inserted into each of sad injectors, said electrical component modifying an electrical characteristic sent from said injector to said control and said electrical component being selected to provide an indication of particular characteristics which have been determined to exist for each said fuel injector, said electrical characteristics including a single value which is associated with a code value, said code value being selected to identify values for two distinct ones of said particular characteristics and said control being able to identify said two distinct ones of said particular characteristics by identifying said code value through said electrical characteristic; said electrical component is a resistor inserted into a circuit for driving said fuel injector, said resistor being selected to provide an identifying code to said control selected to identify characteristics of said fuel injector; said resistor is incorporated into a circuit associated with one driver for driving a coil for powering said fuel injector.
