Question 444Motor Plants - Assistant Engineer70% to pass
If an auxiliary diesel engine equipped with an electric starting system cranks very slowly after repeated attempts to start, the cause could be a/an _______________.
AI Explanation
The correct answer is D) overheated motor windings.
An auxiliary diesel engine with an electric starting system that cranks very slowly after repeated attempts to start is likely due to overheated motor windings in the starting motor. Overheated windings can result in increased electrical resistance, reducing the starting motor's ability to effectively crank the engine. This is the most likely cause among the provided options.
The other options are incorrect because: A) low lube oil viscosity would not directly impact the starting motor's performance, B) low compression pressure would impact engine starting but not the starting motor itself, and C) a broken ring gear teeth would prevent the engine from being cranked, not just slow cranking.
