Question 161Motor Plants - Assistant Engineer
70% to passAuxiliary diesel engines can be automatically shut down as a result of_______________.
Alow lube oil temperature
Blow lube oil pressure
Chigh exhaust temperature
Dhigh cooling water pressure
AI Explanation
The correct answer is B) low lube oil pressure. Auxiliary diesel engines are designed to automatically shut down when the lube oil pressure drops below a critical level. This safety feature is in place to prevent engine damage from inadequate lubrication. Low lube oil pressure is an indication of an issue with the engine's oil supply, and the automatic shutdown prevents further damage from occurring. The other options are not primary triggers for an automatic shutdown. Low lube oil temperature (A) and high exhaust temperature (C) may indicate problems, but they do not directly lead to an automatic shutdown. High cooling water pressure (D) is not a typical shutdown criterion for auxiliary diesel engines.
