🔍 Key Concepts

• Compression rings vs. oil control rings on a diesel piston • How gas pressure sealing is achieved between piston and cylinder wall • The role of piston rings in heat transfer and lubrication control

💭 Think About

• Think about what happens to the high‑pressure combustion gases if there were no compression rings. • Which piston component mainly controls excess lubricating oil in the cylinder — is it the same one that seals compression? • Which of the listed functions would directly affect engine efficiency and compression pressure during the power stroke?

✅ Before You Answer

• Identify which option describes sealing of combustion pressure or its consequences. • Distinguish between rings that control oil and rings that handle compression sealing/heat transfer. • Ask: which choice matches the primary design purpose of compression rings, not a secondary effect.
