In which of the following output devices would you be more likely to find a piezo actuator?
A) linear proportioning solenoid
B) electrohydraulic injector (EHI)
C) non-contact TPS
D) stepper motor

Question

Quizplus · Accepted Answer

Electrohydraulic injectors (EHI) are more likely to use piezo actuators because piezoelectric materials can change shape very rapidly and with great precision when an electric current is applied, making them ideal for the precise control of fuel injection in modern engines.
