Abstract:
A fuel injector apparatus comprising a piezoelectric driving stack and injector assembly wherein a flow control member of the fuel injector apparatus is driven directly by the piezoelectric stack without additional amplification means or interposing elements while the flow area of the nozzle portion is variably adjustable to deliver controlled flow rates in a desired flow profile to improve engine performance and reduce emissions. The injector configuration is adapted to support required flow rates with minimal linear movement of the flow control member.
