Question 1092 Deck Safety

The correct answer is B) Buildup of sludge in the lubricating system. Running a diesel engine at too cool a temperature can lead to the buildup of sludge in the lubricating system. This is because cooler temperatures prevent the proper vaporization and combustion of fuel, resulting in the formation of unburnt fuel and other byproducts that can accumulate as sludge in the engine's lubrication system. This sludge buildup can impair the engine's lubrication and lead to increased wear and tear on mechanical components. The other answer choices are incorrect. Excessive fuel consumption (A) is more likely to occur when the engine is running at too high a temperature. Severe heat stresses on mechanical parts (C) are more likely to occur when the engine is running at too high a temperature. Foaming of the lubricating oil (D) is not a direct consequence of running the engine at too cool a temperature.
