An auxiliary oil pump designed to feed oil to the lubrication circuit at extreme working angles is known as a(n)?

• A. Gerotor pump
• B. Scavenging pump
• C. Vane pump
• D. Emergency pump

Answer: (B)

The correct term for an auxiliary oil pump that is specifically designed to feed oil to the lubrication circuit at extreme working angles is scavenging pump. This type of pump is crucial in ensuring that oil is continuously supplied to engine components under conditions where normal oil flow is disrupted, such as during sharp turns or steep inclines. The scavenging pump effectively collects and returns oil to the lubrication system, thus preventing engine damage that could occur from insufficient lubrication when the engine is operating at unusual angles. In the context of engine lubrication systems, scavenging pumps are often utilized in scenarios where oil can easily move away from pump pick-up points, as seen in high-performance and racing applications. They maintain oil availability in critical areas by removing oil from oil spaces and sending it back to the oil supply or sump. This prevents the risk of oil starvation, which can lead to increased wear and potential engine failure. Other types of pumps mentioned, such as gerotor, vane, and emergency pumps, serve different purposes in lubrication systems but do not specifically address the requirement of maintaining lubrication at extreme angles as effectively as a scavenging pump does.
