🔍 Key Concepts

• Compare camshaft speed to crankshaft speed in two-stroke vs four-stroke diesel engines. • Look closely at the cylinder liner and surrounding cooling space to decide if it is a wet liner or dry liner. • Use the piston position and which passages/valves are open to identify the engine stroke being shown (intake, compression, power, or exhaust).

💭 Think About

• From the illustration, does this engine complete its full cycle in one crankshaft revolution or two? How does that affect camshaft speed? • Do you see cooling water in direct contact with the outside of the liner, or is the liner backed solidly by the block metal? • Is the piston near top or bottom dead center, and which path (to the turbocharger or from the blower/intake) is open at that instant?

✅ Before You Answer

• Verify whether intake ports in the cylinder wall are being uncovered by the piston (a clue to a uniflow two-stroke). • Check if there is a water space surrounding the outer surface of the liner with sealing rings at the lower end (indicating a wet liner). • Confirm which valve or ports are open and the direction of gas flow to decide whether the stroke shown can be the end of the exhaust stroke.

The camshaft turns at the same speed as the crankshaft.

The engine utilizes dry type cylinder liners.
