Where is the oil temperature measured on a
reciprocating engine? - ....ANSWER...Usually at the oil
pressure screen before the oil goes into the engine
passages.
How is oil pressure regulated on an aircraft engine? -
....ANSWER...A pressure relief valve sensors the desired
pressure and sends all of the oil that caused excessive
pressure back into the engine oil sump.
Why do engine manufacturers recommend that engine
lubricating oil be changed at specific intervals? -
....ANSWER...The oil picks up contaminants and carries
them through the engine where they can cause we're.
,Doyle becomes acidic and causes corrosion in the
engine.
What is the purpose of the restricted orifice in the line
between the oil pressure gauge and the engine? -
....ANSWER...The restricted fitting helps dampen any
pulsations in the oil pressure caused by the pump.
What is a hot tank lubrication system for a turbojet
engine? - ....ANSWER...A lubrication system in which the
oil cooler is in the pressure subsystem and they
scavenged oil is not cool before it is returned to the
tank.
What is a cold tank lubrication system for a turbojet
engine? - ....ANSWER...A lubrication system in which the
oil cooler is in the scavenge subsystem, and the
scavenged oil is cool before it is returned to the tank.
What is the main advantage of a Magneto ignition
system over a battery ignition system for an aircraft
reciprocating engine? - ....ANSWER...A Magneto has its
own source of electrical energy, and is not dependent
upon the battery.
,What is the function of the capacitor in the a Magneto? -
....ANSWER...The capacitor minimizes arcing at the
breaker points, and it speeds up the collapse of the
primary circuit as the breaker points open.
What happens in a Magneto ignition system when the
ignition switch is placed in the off position? -
....ANSWER...The primary circuit is connected to ground.
What is checked when a Magneto is internally time? -
....ANSWER...Internally timing a Magneto consists of
adjusting the breaker points so that they will open at
the instant the rotating magnet is in the E Gap position,
and the distributor rotor is in a position to direct the
high-voltage to cylinder number one.
And what position should the ignition switch be placed
when using a timing light on the Magneto's? -
....ANSWER...In the both position.
What type of ignition system is used on most turbine
engines? - ....ANSWER...High-intensity, intermittent
Duty, capacitor discharge ignition systems.
What is the E Gap in the Magneto timing? -
....ANSWER...The E Gap angle is in the position of the
, rotating magnet when the primary current flowing
through the Magneto coil is in the greatest. The breaker
points open when the rotating magnet is in the e-gap
position.
What is the function of an Impulse coupling? -
....ANSWER...An Impulse coupling is a spring driven
coupling between the Magneto and the engine. When
the engine is being started, the impulse coupling holds
the rotating magnet until the Piston passes over it
stops interposition and starts down. The impulse
coupling releases the magnet and a spring spins it fast
so that it can produce a hot and late spark.
How many igniters are used on most turbine engines? -
....ANSWER...2.
What are two types of ignition systems used on turbine
engines? - ....ANSWER...High voltage systems and low
voltage systems.
With which type of turbine engine ignition system is a
glow plug igniter used? - ....ANSWER...A low-voltage
system.
