Piston rings can be plated with chrome or other materials to ____________.

Piston rings can be plated with chrome or other materials to ____________.

• A. increase friction
• B. reduce wear
• C. enhance appearance
• D. improve fuel efficiency

Answer: (B)

Piston rings are designed to create a seal in the engine cylinder, preventing the escape of combustion gases and controlling oil usage. When piston rings are plated with chrome or other materials, the primary goal is to reduce wear. This is crucial because wear can lead to decreased engine performance, increased oil consumption, and even engine failure over time. Plating with materials like chrome enhances the hardness and durability of the rings, allowing them to withstand the corrosive environment of the combustion chamber. This reduction in wear contributes to a longer lifespan for both the piston rings and the engine itself, promoting better overall performance. While improving aspects like friction, appearance, and fuel efficiency may be secondary benefits or related to different components, the primary intention behind plating piston rings is to minimize wear and enhance their longevity.
