🔍 Key Concepts

• Function of the oil scraper ring on a diesel engine piston • Purpose of the drain holes behind the oil scraper ring • Difference between oil control and compression sealing in piston rings

💭 Think About

• Think about what happens to the oil that the scraper ring wipes off the cylinder wall if its normal escape path is blocked. • Consider whether more oil or less oil will remain on the cylinder wall when the drain hole is plugged. • How would a change in oil on the cylinder wall affect how much oil gets into the combustion space and is burned?

✅ Before You Answer

• Be clear on the primary job of the oil scraper ring (it is different from the compression rings). • Visualize the pathway the oil follows: from cylinder wall → behind ring → drain hole → crankcase. • Ask yourself whether a plugged drain hole is more likely to cause greater oil carryover to the combustion space or improved oil control.
