Q

In a modern two stroke, slow speed, internal combustion diesel engine, what is the part of the engine that houses the crankshaft?

🔍 Key Concepts

• Structure and purpose of the crankcase in large slow‑speed marine diesels • Difference between bedplate, frame, and cylinder block in an engine • Where the main bearings that support the crankshaft are located

💭 Think About

• Which engine component actually carries and supports the crankshaft and its main bearings in a large slow‑speed marine diesel? • Does the cylinder block usually see piston/cylinder forces, or does it directly house the crankshaft on this type of engine? • On a slow‑speed crosshead engine, which part forms the base structure that the rest of the engine is built on?

✅ Before You Answer

• Identify which part the main bearings are bolted into • Decide which option forms the lowest structural member of the engine • Confirm which component is specifically associated with the crankcase on slow‑speed two‑stroke diesels
