- Question
The function of oil-control rings is that it
Options- A. lubricates the cylinder wall by releasing oil from its hole
- B. keeps the cylinder wall lubricated by holding oil in its channel
- C. prevents engine oil from going into the combustion chamber and returns excess lubricating oil off the cylinder wall through the return holes in the piston to the oil pan
- D. maintains a seal and prevents escape of burned gases and oil leakage
- Correct Answer
- prevents engine oil from going into the combustion chamber and returns excess lubricating oil off the cylinder wall through the return holes in the piston to the oil pan
