🔍 Key Concepts

• Function of compression rings in an internal combustion engine • How gas pressure and mechanical spring tension help rings seal against the cylinder wall • Effect of temperature on ring-end clearance and sealing

💭 Think About

• Think about which option directly uses the pressure from the burning gases themselves to improve the seal of the rings. • Which choice would actually push the ring harder against the cylinder wall during compression and power strokes, rather than only when the engine is cold or being assembled? • Consider how ring-end clearance changes as the piston and rings heat up; does that usually improve sealing or risk contact and damage?

✅ Before You Answer

• Identify which option involves gas pressure behind the ring rather than just material choice or pre-setting the gap. • Decide whether thermal expansion generally makes the ring ends closer together or farther apart, and how that affects sealing. • Ask yourself which device is designed to work only when cylinder pressure is present, giving a better seal right when pressure is highest.
