Ignition Systems

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
