What explains why EHIs with Piezo actuators respond faster to energization signals from the injector drivers?
A) mechanical movement at the actuator does not depend on building a magnetic field
B) piezoelectric signals travel faster
C) piezo actuators are lighter in weight than solenoid actuators
D) piezo actuators consume much more electricity than solenoid actuators

Question

Quizplus · Accepted Answer

Piezo actuators respond faster because their mechanical movement is directly initiated by the application of an electrical voltage, which causes an immediate change in shape or size without the need to build a magnetic field, unlike solenoid actuators.
