Embracing Speed and Efficiency Piezoelectric Injectors' Game-Changing Impact

46. What explains why EHIs with Piezo actuators respond faster to energization signals from the injector drivers? High accuracy · Quick response · High keeping suspension · Low consumption · Electromagnetic noiseless · High-density mounting is possible by small size · Simple ... I think they are getting better. We used them maybe 4 years ago. So the new technology may be better. In more advanced fuel injectors, piezoelectric actuators have replaced solenoid actuators due to their faster response time. ... then pumps the electrical charge ... ... injection rate is simpler than commercial fuel injectors based on electromagnetic actuators. In order to better prove the latter concept, a more engineered ... It seems that several companies including Siemens already has piezo injectors that can inject at more than 400 bar over what the 6.4 is going to do. Piezoelectric actuators offer several advantages over other types of actuators, including high precision, fast response time, and low power consumption. Piezo actuators (not to be confused with piezo motors) provide motion output proportional to a drive voltage – usually up to one millimeter and high dynamics ... A second actuator type, using piezoelectric material to provide displacement, can provide faster response than a solenoid actuator. However, a piezoelectric ... use in diesel fuel injectors. Sept 2009 – Milestone: Measure and compare piezoelectric and mechanical reliabilities of tape- cast and hot ...
