Question 117Motor Plants - Assistant Engineer

The correct answer is D) Engine speed should be reduced. When operating a large, low-speed, diesel engine with one cylinder secured, the engine speed should be reduced to prevent overloading the remaining operational cylinders. Reducing the engine speed helps to distribute the load more evenly across the functioning cylinders, preventing excessive stress and potential damage. The other options are incorrect because: A) Increasing lubrication to the defective cylinder would not be necessary since it is secured, B) Increasing cooling water temperature would not address the issue of uneven loading, and C) Reducing only the turbocharger speed would not adequately address the overall engine load distribution.
