Engine Lubrication Systems Prep Questions and Answers 100% Pass How are the oil fillers marked on reciprocating engines according to aviation standards? They are labeled "oil" following the guidelines set by 14 CFR part 23. In a dry sump reciprocating engine, where is the oil temperature regulator usually situated? It is typically placed between the outlet of the scavenger pump and the oil tank. How is lubrication typically applied to the gears within the accessory section of an en...

List five functions of the oil in an engine lubrication system. CORRECT ANSWER Cools, Cleans, seals and cushions, prevents corrosion, and reduce friction. The resistance of an oil to flow is known as its ________. CORRECT ANSWER Viscosity. Oil that flows freely has a ____ viscosity. CORRECT ANSWER Low. The oil used in reciprocating engines has a relatively _____ (high or low) viscosity. CORRECT ANSWER High. The measure of the change in viscosity with a given change in temperature is ...

Lubrication Systems (Jepp/Prep/Crane) Questions and Answers Already Passed If a reciprocating engine is consuming an excessive amount of oil without any visible leaks, what is the likely issue? Worn or damaged piston rings. What are the roles of lubricating oil in a reciprocating engine? It minimizes friction between moving components and helps dissipate heat. What are two key properties of engine oil used in aircraft? The oil needs to be light enough for easy circulation but suffi...

Lubrication Systems Test Questions and Answers Already Passed Identify five roles that engine oil performs in a lubrication system. It provides cooling, cleans components, seals and cushions surfaces, guards against corrosion, and minimizes friction. What term describes an oil's resistance to flowing? Viscosity. What kind of viscosity does oil have if it flows easily? Low. What type of viscosity is characteristic of oil used in reciprocating engines? High. What term refer...

Lubrication Systems Review Questions and Answers Already Passed What does the term "viscosity" refer to when discussing engine lubricating oil? Viscosity describes the thickness of the oil and its resistance to flowing. How does a wet sump lubrication system operate? In a wet sump system, the oil is contained within the engine’s crankcase. This setup has limitations like reduced oil capacity, challenges with cooling, and generally higher operating temperatures. What character...

Which of these characteristics is desirable in turbine engine oil? A- Low flash point B- High flash point C- High volatility o :## B The type of oil pumps most commonly used on turbine engines are classified as o :## positive displacement What is the source of most of the heat that is absorbed by the lubricating oil in a reciprocating engine? o :## pistons and cylinder walls What will happen to the return oil if the oil line between the scavenger pump and the oil cooler separates? ...

Lubrication Systems Questions and Answers Already Passed What does the term viscosity refer to in engine lubricants? It indicates the oil's resistance to flowing. What defines a wet sump lubrication system? In this system, the oil is stored within the engine itself. What characterizes a dry sump lubrication system? This system involves keeping the oil in a separate tank, not integrated into the engine. How is the temperature of oil regulated in an aircraft engine with a recipr...

1. What will be the result of operating an engine in extremely high temperatures using a lubricant recommended by the manufacturer for a much lower temperature? o :## *c. The oil pressure will be lower than normal. 2. (1) Gas turbine and reciprocating engine oils can be mixed or used interchangeably. (2) Most gas turbine engine oils are synthetic. Regarding the above statements, o :## *a. only No. 2 is true. 3. An oil separator is generally associated with which of the following? o ...

Automotive Lubrication System Questions and Answers 100% Pass What does the term "friction" refer to in mechanical systems? It describes the resistance encountered when two dry surfaces slide against each other. How can lubrication be defined in the context of machinery? Lubrication involves reducing friction by introducing a slick substance between moving surfaces. What are the main roles of engine oil? Engine oil facilitates easy engine start-up, lubricates moving parts, safegu...
