Higher than normal jacket water temperatures occurring in all cylinders of a diesel engine can result from a/an __________.

🔍 Key Concepts

• jacket water system purpose and flow path in a marine diesel engine • difference between raw (sea) water side and freshwater (jacket water) side of the cooling system • how flow restriction or insufficient cooling water supply affects temperature in all cylinders vs. a single area

💭 Think About

• Which option would realistically affect the temperature of all cylinders’ jacket water at the same time, rather than just one part of the engine? • Think about which choices would reduce the effective cooling of the engine, and whether they act on the oil system, the coolant quantity, or the seawater intake. • For each choice, ask yourself: would this make jacket water hotter, cooler, or stay about normal?

✅ Before You Answer

• Distinguish clearly between the lube oil system and the cooling water system and what each affects. • Consider whether cavitation erosion is a cause or a result of abnormal conditions. • Verify which component, if obstructed, would reduce the heat rejection from the closed‑loop jacket water to the sea.
