Question: What Is The Primary Purpose Of The Oil-to-fuel Heat Exchanger?

What is the primary purpose of changing aircraft engine lubrication oils at predetermined periods?

To prevent the oil from the supply tank from seeping into the crankcase during inoperative periods.

What is one of the functions of the fuel oil heat exchanger on a turbojet engine?

A) To provide a relatively constant oil flow to the main bearings at all engine speeds. B) To protect the oil seals by preventing excessive pressure from entering the bearing cavities.

What is the purpose of the oil valve?

The valve is designed to open when the oil filter becomes clogged or when the oil is too thick. This allows the oil to bypass the filter through a center tube. The oil then goes straight to the engine to prevent starvation and damage.

What is the primary source of oil contamination in a normally operating reciprocating engine?

(8494) – The primary source of oil contamination in a normally operating reciprocating engine is metallic deposits as a result of engine wear. atmospheric dust and pollution.

What will result if an oil screen is completely blocked?

What will result if an oil filter becomes completely blocked? Oil will flow at the normal rate through the system. consists of pressure, breather, and scavenge subsystems. the oil tank to be vented through the normal engine vent.

What will result if an oil filters becomes completely blocked?

What will result if an oil filter becomes completely blocked? B) Oil will flow at the normal rate through the system.

How does oil and air separate in Deoiler?

The oil-contaminated air, now referred to as breather air, flows out of the compartment to the deoiler and is replenished by fresh buffer air flowing past the compartment seals. The deoiler separates the oil from the air, vents the decontaminated air overboard, and discharges the separated oil to the oil pump.

Which type of oil system is most common on turbine engines?

(1) Wet sump oil systems are most commonly used in gas turbine engines. (2) In most turbine engine oil tanks, a slight pressurization of the tank is desired to ensure a positive flow of oil.

How does a fuel oil heat exchanger work?

A fuel/oil heat exchange system is proposed for an aircraft gas turbine engine for heating fuel leaving the aircraft fuel tanks before it enters the engine fuel system. Fuel from the aircraft passes through the heat exchanger prior to entering the fuel system 7 through fuel filter 6.

What could cause abnormally high engine oil pressure?

Dirty or contaminated oil filter: The oil filter is there to filter out impurities from the engine oil. Over time, particles from dust, soot, rust, and gum get deposited in the filter and begin clogging the system. This leads to more resistance and higher oil pressure.

What happens if pressure relief valve fails?

Damage caused by a faulty pressure relief valve Oil pump pressure relief valves can fail in either the open or closed position. This can cause damage to the engine oil filter and to the engine itself. A pressure relief valve that is stuck open can allow too much oil to bleed off.

How does bypass valve work?

The bypass valve is triggered by a spring-loaded mechanism that opens when fluid pressure becomes too high or too low, Winter says. “That acts on a diaphragm that opens a valve to let air flow from the tank into your lungs. When you blow out, it closes the valve and allows the air to flow out into the water.”

What will be the result of operating an engine in extremely high temperatures?

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? A) The oil pressure will be higher than normal. The oil pressure will be lower than normal.

How much expansion space is required for oil tanks?

(1) Each oil tank used with a reciprocating engine must have an expansion space of not less than the greater of 10 percent of the tank capacity or 0.5 gallon, and each oil tank used with a turbine engine must have an expansion space of not less than 10 percent of the tank capacity.
