Next-Level Agility Piezoelectric Injectors Empower Actuator Advancements

I am going to need to determine the PWM on the injectors and then cross reference them to how low impedance injectors operate. So if a Piezo ... The method of testing then is to measure the resistance of the injector at 100v. ... injectors have solenoid actuators and not piezo actuators. Piezoelectric injector testing is a far cry from standard port / PFI injector testing. GDI systems have various ways to trigger their injectors and do so at ... Accordingly, a PICMA® stack actuator with a layer thickness of 60 µm has an approx. 70 times higher capacitance than a PICA stack actuator of the same volume ... However, some piezoelectric materials for sensors or actuators are adopted in elevated temperature environments, such as in applications for ... The ECU then controls various output actuators like fuel injectors. ... • 5 times faster than conventional injectors. 7. Emission Control ... 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. Indeed, piezo ceramic injectors operate faster than injectors with electromagnetic actuators. Piezoelectric injectors can respond faster because they apply ... Piezoelectric actuators can give the same performance from a smaller component, produce higher-resolution movement, and require a lower operating voltage than ... Considering the nonlinearity of a piezoelectric actuator, the complete electro-mechanical-hydraulic model of the piezoelectric injector was established and ...
