🔍 Key Concepts

• Follow the scavenging air (combustion air) path shown in green from the external manifold into the cylinder liner. • Identify the scavenge ports in a two‑stroke diesel where air actually enters the cylinder space above the piston crown. • Differentiate between parts that carry air to the manifold (pipes/ducts) and the actual entry point into the cylinder (ports or valves).

💭 Think About

• Trace the green arrows starting from the air manifold and see where they first cross from the outer casing into the inside of the liner where the piston moves. • Look closely at the letters near the rectangular openings in the liner wall—are they showing air still in a passage, or already entering the combustion space? • Ask yourself: at which labeled point is air no longer in a duct or receiver, but is entering directly into the cylinder volume where fuel will be injected and burned?

✅ Before You Answer

• Verify which letter is located at the scavenge ports in the liner wall, not on an external duct or manifold. • Confirm that, at this letter, the green flow path is crossing the cylinder wall into the piston area, not just moving alongside it. • Make sure the chosen letter is associated with combustion/scavenge air (green color), not with exhaust (brown) or lubricating oil (yellow).
