When an electric current is passed through a coiled wire, a magnetic field is created. This phenomena is called?
Electromotive Force
Electromagnetic Induction
Resistance
Current
Your ignition coil have primary and secondary windings. Which of the two has more windings in their coil?
Primary
Secondary
Both
Neither
TRUE or FALSE.
Spark plug gap helps ensure that the spark produced will consistently occur and generate the proper high temperature to ignite the air-fuel mixture
True
False
A pulser coil (sometimes referred to as a crankshaft position sensor) is a vitally important sensor. What are the basic functions of the pulser coil?
Uses A/C voltage pulses to determine cylinder piston position
To inform the ECM of engine speed
To report to the ECM the exact position of each of the pistons
All Answers Correct
What is a "Waste Spark" ignition system?
Very compact and don’t require large, secondary wires leading from a conventional coil, since this type of igniting transformer resides directly on top of the spark plug
Dedicated to a single cylinder and fires only that cylinder’s spark plug
Splits its discharge voltage to fire two spark plugs simultaneously. Spark is not only delivered to the cylinder that’s on the compression stroke, but also delivered to the paired cylinder that’s on its exhaust stroke
None of these answers are correct
TRUE or FALSE.
Ignition timing is when a cylinder’s timed ignition event occurs, relative to the crankshaft and the piston’s position
True
False
What is fixed ignition timing?
The ignition timing does not change
and always occurs at the same point
This uses mechanical means to
advance or retard the ignition event
An electronic control unit uses a
variety of sensors to determine the optimum
time for the ignition event to occur
All of the answers are correct
What is mechanical ignition timing
The ignition timing does not change
and always occurs at the same point
This uses mechanical means to
advance or retard the ignition event
An electronic control unit uses a
variety of sensors to determine the optimum
time for the ignition event to occur
None of the answers are correct
What is electronic ignition control?
The ignition timing does not change
and always occurs at the same point
This uses mechanical means to
advance or retard the ignition event
An electronic control unit uses a
variety of sensors to determine the optimum
time for the ignition event to occur
All of the answers are correct
TRUE or False.
Capacitor discharge ignition can operate with A/C or D/C power sources
True
False
TRUE or FALSE.
A transistor acts like an electronic switch
True
False
