Question 167Motor Plants - Assistant Engineer
70% to passAuxiliary diesel engine electric starting motors use _______________.
A400 cycle per second motor-generator power
Bbattery power direct current
Clow amperage, high voltage AC power
Dalternating current transformers
AI Explanation
The correct answer is B) battery power direct current. Auxiliary diesel engine electric starting motors use battery power direct current (DC) to provide the necessary electrical energy to start the engine. This is a common practice in marine applications, as batteries can store the required electrical charge and deliver the high current needed to crank the engine during startup. The other options are incorrect because: A) 400 cycle per second motor-generator power is not used for starting diesel engines, C) low amperage, high voltage AC power would not have enough current to turn over the engine, and D) alternating current transformers are not directly used to start diesel engines.
