Question: 1 / 440

Is it true that engine oils used in steam engine external bearings are typically light and medium-bodied oils appropriate for splash circulating systems?

True

False

The correct answer is true. Engine oils used in steam engine external bearings are indeed typically light and medium-bodied oils that are suitable for splash circulating systems. These oils possess specific properties that allow them to maintain adequate lubrication in the unique operating conditions of steam engines, where the high temperatures and moisture levels can impact oil performance. Light and medium-bodied oils provide the necessary viscosity for effective lubrication without causing excessive drag or resistance in the system.

In splash circulating systems, the oil is dispersed by the motion of the engine components, which means that the oil must be appropriately formulated to circulate effectively and reach all critical surfaces without breaking down quickly. Using the correct grade of oil in these systems is crucial for maintaining efficient operation and ensuring the longevity of the bearings and other moving parts.
