Innovation Unleashed Piezoelectric Injectors Propel Engine Performance

The method of testing then is to measure the resistance of the injector at 100v. ... injectors have solenoid actuators and not piezo actuators. 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 ... 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 ... The piezoelectric element represents the latest generation of injector actuators and ensures higher performance, in particular faster response, than the ... An actuator giving high displacement was successfully produced by stacking piezoelectric disks. Key words: Piezoelectric Ceramics, Fuel Injector, Actuator, PZT, ... Piezoelectric actuators offer several advantages over other types of actuators, including high precision, fast response time, and low power consumption. High accuracy · Quick response · High keeping suspension · Low consumption · Electromagnetic noiseless · High-density mounting is possible by small size · Simple ... Piezoelectric injectors uses this characteristic to provide fast, precise control of injection timing,while eliminating all other moving parts. In more advanced fuel injectors, piezoelectric actuators have replaced solenoid actuators due to their faster response time. ... then pumps the electrical charge ... ... actuators and key working units, and then changing the control settings. 2. Methods 2.1. Test object The tests were carried out on the Siemens VDO ...
