Accelerating Engine Performance The Power of Piezoelectric Injectors

The expansion can be precisely repeated much better than using electro-magnetic solenoid style injectors. This allows for better fuel metering ... The piezoelectric element represents the latest generation of injector actuators and ensures higher performance, in particular faster response, than the ... Aerospace and Defense: The high precision and fast response times of piezo actuators make them valuable in aerospace applications like fuel injectors, active ... ... injector length. As the piezo actuator is integrated in the housing, the injectors are significantly slimmer than solenoid valve injectors ... Piezo actuators have response times on the order of just a few tenths of a millisecond. The piezo-electric technology was commercialized in common rail ... 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 ... ... injector length. As the piezo actuator is integrated in the housing, the injectors are significantly slimmer than solenoid valve injectors and thus require ... As a Piezo injector performs faster, it can carry out more injections per cylinder stroke and allows for higher fuel system pressures. This ... The piezo actuators respond more precisely and repeatably providing more accurate fuel flow control. The first generation of piezo injectors ... The ECU then controls various output actuators like fuel injectors. ... • 5 times faster than conventional injectors. 7. Emission Control ...
