Technician A says piezoelectric injectors rely on stacked crystals that expand when a voltage is applied. Technician B says piezoelectric injectors are slower acting than solenoid-type injectors. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because piezoelectric injectors do indeed use stacked crystals that expand when a voltage is applied, which changes the injector needle position to allow fuel injection. Technician B is incorrect because piezoelectric injectors are actually faster acting than solenoid-type injectors, offering more precise control over fuel injection.
