This tests the engineer's respect for the machinery. The "killer" here is hydraulic lock (water or oil on top of the piston).

More cylinder oil, not less. (Medium-speed: less oil to avoid carbon. Slow-speed: more oil to neutralize acid and seal rings at low load). This tests the engineer's respect for the machinery

They are designed to vent pressure, but flame emission can be fatal. Diesel Engine Management Test Summary | PDF -

| Topic | Common (Wrong) Answer | Exclusive Slow-Speed Answer | Why? | | :--- | :--- | :--- | :--- | | | "Air enters near TDC." | Air enters just after TDC (e.g., 10-20° after TDC) on the power stroke. | Slow-speed engines need high starting torque. Air must push the piston down, not just over the top. | | Cylinder Lubrication | "Lubricate continuously like a 4-stroke." | Intermittent, high-pressure shot timed with piston ring pack passage over scavenge ports. | Continuous oil would wash past the large piston rings and contaminate the scavenge air. | | Scavenge Fire Cause | "Fuel leak." | Unburned fuel accumulation due to late injection + piston ring blow-by. | Slow-speed engines have a large under-piston volume; oil/fuel sludge there ignites from hot combustion gas blow-by. | | Jacket Water Temp | "Keep as cool as possible (70°C)." | Maintain 85-90°C. Never cold start below 60°C. | Cold slow-speed engines cause "cold corrosion" from sulfuric acid condensation on large cylinder liners. |

: This is typically caused by exhaust gas leakage into the cooling water system. Maintenance During UMS Operation :
