Recip Magnitos Flashcards
The spark used for starting an aircraft must occur before or after
After
What are the two types of starting systems
Impulse coupling
Induction vibrator
What is the mechanical system that uses a spring to spin the magnet to produce a hot retarted spark for starting the engine is?
Impulse coupling
What’s the position for the ignition switch used in an induction vibrator ignition system
Off
Left
Right
Both
Start
What magneto does the induction vibrator system start with left or right magnito
Left
The induction vibrator changes dc into
Pulsating dc current
When the ignition switch for an engine equipped with an induction vibrator ignition system is held is the start position, sparks occur in the spark plug gap when the _____ breaker points open
Retard
The spark between the breaker points occurs when the points are
Open
The capacitor in a battery ignition system is installed in a ______ with the breaker points.
Parallel
The ignition switch of a battery ignition system is installed in _____ with the breaker points
Sierrs
Two types of magneto ignition system are
High tension
Low tension
The three circuits in a magnito are
Magnetic
Primary
Secondary
What is e gap
The position of the rotating magnet in a magnito when the breaker points are timed to open
What is the p lead
Wire that connects the primary winding to the ignition switch
What is a safety gap
Location in a magneto that allows spark to jump to ground from the secondary circuit before the voltage rises high enough to damage the secondary insulation.
What does a low tension magneto system have that a high tension one does not.
The low tension has a high tension transformer at the spark plug
What is a retarted spark
Ignition sparks for starting an engine, timed to occur later than the normal sparks
What does the impulse coupling do
A spring loaded coupling between the magneto shaft and the drive gear inside the engine, used to produced a hot, late spark for starting the engine
What does the impulse coupling use to lock
Can and flyweights and a spring to hold tension
What are the two types of systems for auxiliary starting systems
Impulse coupling
Induction vibrator system
What is the shower of sparks
The registered trade name of a popular type of induction vibrator starting system for a recip engine
What is a system that was suppost to replace single magnetos
The double magneto
What does a double magneto share
A magnet
When timing a magneto what are the two types of timing
Internal timing
Engine to magneto timing
What is internal timing
The adjustment of the breaker points of a magneto so they will begin to open at the time the magnet is in the e gap position
What must the magneto be in to internally time it
E gap position
What tools can be used to time the engine
Rotor holding tool
Timing plate
Magnito timing light
Timing marks
Time rite indicator
What is carbon track
A trail of high carbon despostied by an arc across a high volatage component such as a distributor block
What are the two types of high tension leads for a spark plug
Angled lead
Straight lead
What are the two types of spark plugs
All-weather spark plugs
What are the two sizes of spark plugs
5/8-24 and 3/4-20
How can an ignition harness be tested for leaks
Ignition harness tester
How are spark plugs moved
To the next plug in the firing order
What is ice bridging
A spark plug failure that occurs when starting a recip engine in extremely cold weather. Water vapor for the combustion process condenses on the spark plug electrodes and freezes bridging the fire plug.
What are the two types of electrodes
Fine wire and massive wire
What are the two types of heat ranges
Cold spark plug
Hot spark plug
