Abstract

The present invention discloses a method of operating an injector comprising a piezoelectric actuator for displacing an injector needle to open an injector port of a fuel injector, wherein a voltage in an operating voltage range is applied to said piezoelectric actuator to cause displacement of said needle, and wherein, at predetermined conditions, a recovery voltage equal or superior to the reverse coercive field voltage value of said piezoelectric actuator is applied to said actuator. <IMAGE>
