Question 478Motor Plants - Assistant Engineer
70% to passCorrosion and grooving on the blading of an exhaust driven turbocharger is caused by certain components of residual fuel oils. These components are vanadium, sodium, and _______________.
Acopper
Bcarbon
Chydrogen
Dsulfur
AI Explanation
The correct answer is D) sulfur. Corrosion and grooving on the blading of an exhaust driven turbocharger is caused by certain components of residual fuel oils, specifically vanadium, sodium, and sulfur. Sulfur is a common contaminant in residual fuel oils and can react with other components to form corrosive byproducts that damage the turbocharger blades. The other answer choices are incorrect because copper, carbon, and hydrogen are not the primary culprits for this type of turbocharger damage. Copper and carbon are not typically associated with the corrosive effects on turbocharger blades, and hydrogen is a gaseous element that does not directly contribute to the corrosion process in this case.
