Technician A says that a major advantage of a twin-actuator EUI is that the nozzle opening is 'soft'. Technician B says that 4-terminal EUIs are not so well suited to multipulse injection than the older 2-terminal EUIs. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because a twin-actuator EUI (Electronically Unit Injector) allows for a 'soft' nozzle opening, which can improve the injection process by making it smoother and reducing engine noise. Technician B is incorrect because 4-terminal EUIs are actually better suited for multipulse injection due to their enhanced control capabilities compared to the older 2-terminal EUIs.
