Question 241Motor Plants - Assistant Engineer

The correct answer is C) alkalinity. The adverse effects of burning high sulfur fuel can be compensated for by using a cylinder oil with sufficient alkalinity. High sulfur fuels produce acidic combustion byproducts, which can be neutralized by the alkaline additives in the cylinder oil. This helps prevent corrosion and engine wear. The other answer choices, such as dispersant additives, pour point depressive additives, and ignition quality, do not directly address the issue of neutralizing the acidic byproducts from high sulfur fuel combustion.
