Question 115Motor Plants - QMED70% to pass
Auxiliary diesel engine electric starting motors use _______________.
AI Explanation
The correct answer is A) battery power direct current.
Auxiliary diesel engine electric starting motors use battery power direct current (DC) to provide the necessary power to crank and start the engine. This is because diesel engines require a high amount of starting torque, which can be more effectively provided by a DC battery system rather than an alternating current (AC) power source.
The other answer choices are incorrect because: B) 400 cycle per second motor-generator power is not typically used for diesel engine starting, C) alternating current transformers are not the power source for the starting motor, and D) low amperage, high voltage AC power would not be able to provide the necessary torque to start a diesel engine.
