🔍 Key Concepts

• How a low-speed main propulsion diesel engine’s cylinders are lubricated compared to medium/high-speed engines • When cylinder liner and piston ring contact forces, temperature, and wear are highest in the cycle • Whether cylinder lubrication is designed as a continuous timed system or only at special operating conditions

💭 Think About

• Think about which stroke has the highest gas pressure and temperature and the greatest load on the piston rings against the liner. • Ask yourself: is effective lubrication more critical when the engine is actually doing work, or when it is just being compressed or standing by? • Consider whether cylinder lubrication is meant to protect the liner all the time the engine runs, or mainly at low load/standby conditions.

✅ Before You Answer

• Identify during which stroke the engine delivers useful work to the crankshaft. • Decide if cylinder lubrication is normally used only at low load or standby, or during regular running at sea. • Recall that cylinder lubrication on low-speed engines is usually metered and timed to coincide with specific crank angles during normal operation.
