Question

If an engine is operated in a tilted position for extended periods, which lubrication

system is most likely to ensure reliable oil supply to all parts?

The correct answer is

Dry sump lubrication system

The problem is a tilted engine: in a wet sump the oil pools at the bottom of the sump, and when tilted the oil runs to one side and can uncover the pump pickup, starving the engine of oil.

In a dry sump system the oil is not kept in the sump; scavenge pumps continuously draw it into a separate external tank, and a pressure pump feeds it to the bearings from that tank.

Because the supply is taken from a dedicated remote reservoir rather than a pool in the crankcase, the dry sump keeps delivering oil reliably even when the engine is tilted or subjected to steep angles for long periods.

Splash and oil-mist systems also rely on oil sitting in the crankcase, so they suffer the same tilting problem as the wet sump.

Hence, the answer is Dry sump lubrication system.
