Technician A says that E3 injectors are better suited to multi-pulse injection because the injection pressure is not required to collapse within the EUI between injection pulses. Technician B says that at any time the NCV actuator is energized in a E3 injector, pressure rise is created in the EUI pump chamber. Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

E3 injectors, designed for efficiency and precision in fuel delivery, allow for multi-pulse injection without needing the injection pressure to collapse between pulses, as stated by Technician A. Technician B is correct in stating that energizing the NCV (Nozzle Control Valve) actuator in an E3 injector generates a pressure rise in the EUI (Electronic Unit Injector) pump chamber, which is a fundamental aspect of how E3 injectors operate.
