The ignition system needs to produce high voltage to ignite the air- fuel mixture.
True
False
Mutual induction is used.......
inside the ignition coil
so that a low voltage can be transformed into a higher voltage
to operate the pulser coil
both inside the ignition coil and so that low voltage can be transformed into higher voltage
The spark plug gap....
Puts a strain on the ignition coil if the gap is too large
could cause a poor combustion event if it's too close.
could cause a misfire
all of these events could occur
Ignition timing is variable on all models
True
False
Ignition advance........
is when the timing event happens at TDC
is when the ignition event happens after TDC
is when the ignition event happens sooner than the base timing
is when the ignition event happens later than the base timing
DC based ignition systems are common on large models
True
False
CDI ignition systems use mechanical points to control the ignition event
True
False
If the spark plug gap becomes damaged, it may cause an ignition misfire
True
False
The Pulser coil will produce ______ voltage
AC
DC
If the ignition coils fails on a motor that uses dual lead ignition coils
only the single cylinder will be affected
only the two cylinders that are connected to that coil will not produce an ignition event
only the ignition system timing will be affected
the ignition will be disabled to prevent motor damage
A transistor is used.....
as a one-way valve for electricity
to store electrical energy
like an electronic switch
to resist the flow of current
Mechanical contact points......
need to be checked and serviced regularly
are very durable and trouble free
are used on modern fuel injected motors
are a solid state device used in place of a pulser coil.
A battery based ignition system uses a lighting coil to power the ignition system.
True
False
What are the methods used to control ignition timing?
Mechanical
Electronic
Fixed
All of these options
What is true about a battery based ignition system?
The spark energy varies with motor RPM
it is only used with fixed ignition timing
Is only used on modern fuel injected motors
It can provide stable ignition at all motor rpms
A CDI ignition...
is always an AC system
is always a DC system
can be designed to be either an AC or DC based system
is only used on large performance motors
If a component in an ignition system causes a running issue, it could be due to...
a misfire
advance ignition
wear
based timing
A winding...
is used in ignition coils
has protrusions called reluctors
is adjusted using a timing light
is a type capacitor
The voltage produced by an ignition coil...
can be very dangerous
may exceed 10,000 volts
is produced by mutual induction
All of these options
A spark plug is installed into the combustion chamber...
and must be designed to withstand a very harsh operating environment
and must be serviced or replaced regularly
and has threads that allow it to be screwed into the cylinder head
All of the options
