Question

Semi pressure system does not enables higher bearing loads and engine speeds to be employed as compared to splash system.

(a) True

(b) False

The question was asked in an interview for job.

The above asked question is from Classification of Lubricating System topic in section Engine Friction and Lubrication of IC Engine

Answer 1

The correct answer is:

(a) True

In a semi-pressure lubrication system, the oil is supplied under pressure to certain engine parts, but not as extensively as in a full-pressure system. This limits its ability to handle higher bearing loads and engine speeds compared to a splash system or a full-pressure system. The splash system relies on the movement of engine parts to distribute oil, and the semi-pressure system still relies on gravity or low-pressure pumps, making it less efficient for high-load or high-speed conditions.
