🔍 Key Concepts

• Exhaust gas flow path in a two-stroke diesel engine (from cylinder ports/valves to the manifold and then out of the engine) • Color legend in the illustration for exhaust versus scavenging air, lube oil, and water • Difference between components that handle exhaust inside the cylinder (like ports/valves) and the final discharge point from the engine

💭 Think About

• Starting at the cylinder where combustion occurs, can you trace the orange-colored exhaust path and see where it finally leaves the engine casing? • Among letters K, J, N, and V, which one points to the location where exhaust gas would be on its way out of the engine, not just circulating within a manifold or passage? • Does the labeled point connect directly to an external pipe or uptakes that would logically lead toward the funnel/stack?

✅ Before You Answer

• Verify which color in the legend represents exhaust gas and follow only that color in the drawing. • Check whether the chosen letter is at a point after exhaust has left the cylinder and joined the main exhaust manifold, on its way out of the engine. • Make sure you are not choosing a label that marks scavenge air or cooling water passages that may look similar but are shown in different colors.
