Name this component
Coil
Stator
Transformer
What are these?
Distributor Rotors
Distributor Caps
Distributor Coils
Coil Packs
Which part is responsible for igniting the air-fuel mixture in gasoline engines?
Ignition Coil
Spark Plug
Ignition Lock Cylinder
Glow Plug
Which of these can transform the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel
All because they are ignition coils and coil packs.
Types of Spark Plugs. Choose all that apply.
Iridium
Stainless
Copper
Platinum
This transfers the voltage from the ignition coil to the spark plugs.
Can be found inside the Distributor Cap
Secret
What does “DIS” stand for/mean?
“Do It Self” – system
“Dance In Sun” system
Distributorless Ignition System
Destabilisorless Ignition System
How many ignition coils are needed in a “Waste Spark” system in a 4 cylinder engine?
One
Two
Three
Four
What does a “coil on plug” system means?
Means “coil on main plug”
Means there is a coil for each spark plug
Actually means plug on coil but reversed because of electrical flow
Means there is a coil for each connector plug
Dark black lines on a spark plugs porcelain can indicate?
Fouled
Carbon tracking
Excessive gap
Bad coil
Why is a spark plug gap important?
A:Because the spark has to jump the gap for ignition
B:Because if the gap is too big, it influences the spark
C:Because if the gap is too small, it influences the spark
All the above A,B & C are correct
Why did car manufacturers do away with the distributor type ignition system?
A:Because there is not enough saturation time for the one coil
B:Because high-tension leads, rotor and rotor gaps gave issues
C:The mechanical system wears out, and become inaccurate
All the above A,B & C are correct
What are the advantages of a “coil on plug” system?
A:More saturation time for each separate coil
B:No high tension leads to give issues
C:More accurate control over the quality of spark
All the above A,B & C are correct
Why do we need an IGNITION system?
A:To create a high voltage in the high-tension lead
B:To create voltage high enough to jump the spark plug gap
C:To create a spark at the right time
All the above A,B & C are correct
