🔍 Key Concepts

• Scavenging ports in two-stroke diesel engine liners and how they are arranged • How piston ring gaps interact with ports or openings in the cylinder wall • Differences between purposes of ring pinning vs purposes of lubrication and wear distribution

💭 Think About

• On a two-stroke diesel, what special openings exist in the cylinder wall that are not present (or are different) in many four-stroke designs? • What could happen if a piston ring gap lines up with one of these openings during engine operation? • Which option describes a problem that would be serious enough that designers would add a small pin to physically lock ring position?

✅ Before You Answer

• Identify which options relate to port openings in the liner rather than just lubrication or wear • Consider which function of the pin is mechanically possible (can a small pin really reduce blow‑by along the whole gap?) • Decide which choice prevents mechanical damage to the ring or liner rather than offering only a small efficiency gain
