Q

Which of the listed design features is most common with a two-stroke cycle, low-speed main propulsion diesel engine?

🔍 Key Concepts

• Two-stroke vs four-stroke diesel design (how power is developed every revolution) • Low-speed main propulsion engines used on large ships (typical construction features) • Difference between trunk-type pistons and crosshead pistons

💭 Think About

• Think about what very large, slow-turning main propulsion engines on big ships physically look like inside—how are the pistons connected to the crankshaft? • Which option describes a feature that helps handle very long strokes and high side forces on the piston rod, common in huge low‑speed engines? • Which choices sound more like medium‑speed or high‑speed diesel engine features rather than massive low‑speed ones?

✅ Before You Answer

• Identify which choice is specifically associated with very large, slow‑speed, two‑stroke marine diesels, not small or medium engines. • Check which option relates to how the piston’s motion is guided and side forces are taken, especially in long-stroke engines. • Eliminate any options that are more typical of medium‑speed, four‑stroke, or geared engines rather than direct‑drive low‑speed main propulsion units.
