Answer :
Final answer:
The component that separates the air/fuel mixture from the lubricating oil in an internal combustion engine is the piston rings. They maintain a seal that prevents mixing the two substances, which is essential for engine performance. Proper functioning of the piston rings is vital for preventing oil consumption and maintaining engine efficiency.
Explanation:
Separation of Air/Fuel Mixture and Lubricating Oil
The question asks about the component that separates the air/fuel mixture from the lubricating oil in an internal combustion engine. The correct answer is:
- B. Rings
The piston rings serve an essential function in engines by maintaining a seal between the combustion chamber and the crankcase, preventing the mixing of the air/fuel mixture with lubricating oil. During the engine's operation, the piston moves up and down within the cylinder, and the rings ensure that gases produced by the combustion process do not escape into the oil chamber, thereby maintaining engine efficiency and performance.
For example, if the piston rings wear out or fail, it can lead to oil consumption issues and exhaust smoke, as well as a reduction in performance due to loss of compression. Therefore, the pistons rings are crucial for both efficiency and engine longevity.
