Question

Quizplus · Accepted Answer

When Caterpillar single actuator MEUIs (Mechanically Actuated Electronically Controlled Unit Injectors) are energized by the ECM (Electronic Control Module) drivers, the voltage peaks at over 100 V-DC. This high voltage is necessary to quickly energize the injector solenoid to achieve the precise timing and fuel delivery required for efficient engine operation.
