Oilers/Plant Tenders (HHC) Civil Service Practice Exam

In a splash lubrication system, what is a disadvantage?

1. The oil quantity is precisely controlled

2. The oil cannot reach all engine parts

3. The oil splashing cannot be regulated

4. The system is overly complex

The correct answer is: The oil splashing cannot be regulated

In a splash lubrication system, one notable disadvantage is that the oil splashing cannot be regulated effectively. This is because the oil relies on the motion of engine components to be distributed throughout the engine. When the engine parts move, they generate splashes of oil, which can lead to uneven lubrication and potentially inadequate coverage of all areas that require oil. This can cause certain components to experience insufficient lubrication, potentially leading to wear and failure over time. While the other aspects of the system might have specific characteristics, such as the oil quantity being relatively less precise or the oil not reaching all engine parts adequately, the key issue with regulation stems from the inherently uncontrolled nature of how the oil is splashed and dispersed. Therefore, the lack of regulation in oil distribution poses a significant risk in maintaining optimal engine performance and longevity.
