Question 296Motor Plants - Assistant Engineer
70% to passTo minimize corrosion, fuel oil strainer disks, spacers and scraper blades are made of_______________.
Abrass
Bcopper
Ciron
Dmonel metal or stainless steel
AI Explanation
The correct answer is D) monel metal or stainless steel. Fuel oil strainer disks, spacers, and scraper blades are typically made of monel metal or stainless steel to minimize corrosion. These materials are resistant to the corrosive effects of fuel oil, which can degrade components made of other metals like brass, copper, or iron. Using corrosion-resistant materials helps extend the lifespan of these fuel system components and ensures proper functioning of the fuel oil strainer. The other options (A, B, C) are not correct because brass, copper, and iron are more susceptible to corrosion in a fuel oil environment compared to monel metal or stainless steel.
