Exam 26: Dual-Actuator Eui Systems

What is the equivalent of the control cartridge solenoid in a single actuator EUI in a twin actuator, E3 EUI?

Technician A says that Volvo use E3 injectors in their post-2013 MY engines. Technician B says that Detroit Diesel use E3 injectors in their post- 2013 MY engines. use twin actuators. Who is correct?

Which of the following is the equivalent standard displacement of a Volvo VE D13 engine?

Technician A says that in an E3-fueled engine, at any moment fuel is being injected to the engine cylinder, the SV actuator must be energized. Technician B says that whenever fuel is being injected to the engine cylinder the NCV actuator must be energized. Who is correct?

What electrical pressure is used to initiate the E3 actuators on post-2007, Volvo-Mack engines?

What do Caterpillar call their 4-terminal MEUI?

Where are the injector drivers located in a Series 60 engine using E3 EUIs managed by DDEC VI electronics?

Technician A says that Volvo-Mack E3 fuel calibration codes are printed on the side of each injector. Technician B says that Detroit Diesel E3 fuel calibration codes are factory programmed at initial assembly and should not be changed during the life of the vehicle. Who is correct?

How is fuel delivered from the cylinder head fuel galleries to twin-actuator E3 electronic unit injectors (EUIs) in Caterpillar, Detroit Diesel, and Volvo-Mack engines?

What distinguishes a dual actuator EUI from a single actuator version?

When an E3 EUI is actually injecting fuel to the engine cylinder, what is the status of the actuators?

What is the primary advantage of the E3 EUI over previous generations of single-actuator EUIs?

Which of the following is another way of describing the nozzle control valve (NCV) used in an E3 EUI?

Which of the following must happen to enable a set of E3 injectors to no-fuel and therefore shutdown, an engine?

What is the primary function of the spill valve actuator used in an E3 injector?

Technician A says that whenever an E3 injector is changed out, it is important to drain the EUI fuel supply gallery prior to removing the injector. Technician B says that when one E3 injector is changed out, the calibration codes of the unchanged five injectors must be reprogrammed.. Who is correct?

After replacing a set of E3 injectors in a Mack MP8 engine, the engine rhythmically hunts after being started. Technician A says that a new set of calibration codes should be downloaded and flashed to the EECU. Technician B says that the calibration codes are inscribed on the E3 injector and should be reprogrammed to the EECU. Who is correct?

Which of the following components function similarly in both single- and twin-actuator EUIs?

How many terminals are there on a E3 injector?

What mechanical feature defines the limits within which a 4-terminal EUI pulse width must take place?
