- Chapter 7: Aircraft Systems › Oil Systems
Oil Systems The engine oil system performs several important functions: • Lubrication of the engine’s moving parts • Cooling of the engine by reducing friction • Removing heat from the cylinders • Providing a seal between the cylinder walls and pistons • Carrying away ... contaminants Figure 7-17. Wet-sump oil system. Reciprocating engines use either a wet-sump or a dry-sump oil system. In a wet-sump system, the oil is located in a sump that is an integral part…

Figure 6-10. Oil pressure adjustment screw. The current trend is toward electrical transmitters and indicators for oil and fuel pressure-indicating systems in all aircraft. In this type of indicating system, the oil pressure being measured is applied ... deck. This type of indicating system replaces long fluid-filled tubing lines with an almost weightless piece of wire. Oil Temperature Indicator In dry-sump lubricating systems, the oil temperature bulb may be anywhere in the oil inlet line between…
- Chapter 6: Lubrication & Cooling Systems › Reciprocating Engine Lubrication Systems › Oil Cooler Flow Control Valve
Oil Cooler Flow Control Valve As discussed previously, the viscosity of the oil varies with its temperature. Since the viscosity affects its lubricating properties, the temperature at which the oil enters an engine must be held within close limits. Generally ... oil leaving an engine must be cooled before it is recirculated. Obviously, the amount of cooling must be controlled if the oil is to return to the engine at the correct temperature. The oil cooler flow control valve determines which…
