🔍 Key Concepts

• Difference between splash, pressure, and gravity lubrication systems • How journal bearings in medium and large diesel engines receive oil • Why critical engine parts need a continuous, reliable oil supply under load

💭 Think About

• Think about whether journal bearings are lightly or heavily loaded parts and what that implies about the kind of oil delivery they need. • Ask yourself: does this bearing rely on random movement of oil, or a controlled flow at a known rate and pressure? • Consider which system type is typically used in larger marine diesel engines that must run for long periods under high load.

✅ Before You Answer

• Verify which system type uses a pump to force oil through passages directly to bearings. • Confirm which systems (splash or gravity) are usually found only on small, simple, or low‑speed engines. • Make sure the option you pick can maintain adequate oil film at all engine speeds and loads.
