Abstract
A fuel injector includes a piezoelectric actuation mechanism and a sensor configuration to measure the condition of the actuation mechanism as well as an associated fuel rail. The sensor configuration includes a piezoelectric sensor with an output signal with significantly reduced distortion that accurately reflects control signals provided to the piezoelectric actuation mechanism.
