Revolutionizing Actuators Piezoelectric Injectors Drive Innovation

By eliminating the hydraulic servo mechanism between the actuator and nozzle needle, very fast injector response times are possible. Direct-acting piezoelectric ... 46. What explains why EHIs with Piezo actuators respond faster to energization signals from the injector drivers? Aerospace and Defense: The high precision and fast response times of piezo actuators make them valuable in aerospace applications like fuel injectors, active ... In more advanced fuel injectors, piezoelectric actuators have replaced solenoid actuators due to their faster response time. ... then pumps the electrical charge ... While direct actuator's stroke is generally lower than 100 μm, amplified piezo actuators can reach millimeter strokes. ... piezoelectric fuel injectors ... According to Bosch (who brought Piezo injectors to market) a Piezo actuator can act up to 5 times faster than a standard injector solenoid, and ... #injectors #electric #piezo #diesel #automotive #auto #mecaniclife #механик ... than tension. The ratio of the rotations, or the gear ratio ... I think they are getting better. We used them maybe 4 years ago. So the new technology may be better. The major advantage of piezoelectric injectors is their speed of operation and the repeatability of the movement of the valve. The dilation and retraction ... Compared to the electromagnetic nozzle, piezo nozzles consume less fuel and have higher efficiency [4]. BOSCH piezo injectors are the most common injectors.
