Question 10Motor Plants - 1st Asst/Chief70% to pass
Which of the following procedures should be carried out to permit the continued operation of a crosshead engine with a leaky aftercooler?
AI Explanation
The correct answer is D) Blank off the cooling water lines and run at reduced speed.
This is the correct procedure because a leaky aftercooler on a crosshead engine can lead to contamination of the engine lubricating oil, which could cause significant damage if not addressed. Bypassing the aftercooler or switching to diesel fuel would not resolve the underlying issue. The proper course of action is to blank off the cooling water lines to the aftercooler and operate the engine at a reduced speed to minimize the impact of the leak until the aftercooler can be repaired or replaced.
The other answer choices are incorrect because they do not address the root problem or could potentially cause further damage to the engine.
