Where is the oil temperature bulb typically located on a dry sump reciprocating engine?

In a dry sump reciprocating engine, the oil temperature bulb is typically located within the oil tank. This positioning allows for an accurate reading of the oil temperature as the oil is contained and can reflect the temperature of the oil before it circulates through the engine. Monitoring oil temperature in this manner is crucial for the operation of the engine since it helps ensure the oil is at an appropriate temperature for optimal lubrication and performance.

Locating the temperature bulb in the oil tank offers the benefit of capturing the highest and most stable oil temperature, providing valuable information for the engine's operational parameters. Additionally, placing it in the oil tank avoids the influence of varying temperatures that might occur in other parts of the system, such as the oil cooler or the inlet line, where temperature changes can be more pronounced due to the dynamic operation of the engine.
