Technician B Technician A states that when the driver turns the key to the start position, an
electrical connection is made between the vehicle battery and the secondary
winding of the ignition coil. Technician B states that as the engine is cranked, a
switching circuit turns the primary ignition coil circuit on and off. Who is correct?
Induction Coil The component the ignition system uses to convert low-voltage and high current
into high voltage and low current is called the:
A distributor. All of the following components are common to all ignition systems EXCEPT:
Coil-on-plug The latest form of ignition system is the ________________.
Contact breaker point ignition A(n) ________________ system is a mechanical ignition system with a switch, called
contact breaker points.
Step-up transformers Ignition coils are basically:
Induction Coil Which of the following does the ignition system use to convert relatively low-
voltage and high-current flow into very high-voltage and very low-current flow?

,Engine Performance & Emissions.pdf Engine Performance & Emissions.pdf Engine Performance & Emissions.pdf
Ignition switch The ____________ is used to connect the ignition system to the battery during
operation and disconnect it from the battery to turn the engine off.
High-tension leads The ____________ connect(s) the coil to the distributor cap center terminal and the
distributor cap side terminals to the terminals on the top of the spark plugs.
Spark plugs Which component of the ignition system is threaded into the top of each cylinder
and provides a place for the spark to jump within the combustion chamber?
Torque. Spark plug cooling is affected by spark plug:
Operating temperature Spark plugs are identified by three different features: thread size or diameter,
reach or length of the thread, and heat range or ______________.
Taper Spark plugs either use a _______________ design or a washer type of gasket to form a
seal between the spark plug and the cylinder head.
Technician B Technician A says that spark plug heat range is how much heat spark plugs can
physically handle. Technician B says using the wrong heat range plug can result in
pre-ignition. Who is correct?

Ignition Coils In distributorless ignition systems, the distributor is eliminated and replaced by
multiple _____________.
Coil-on-plug ignition system Which of the following systems has the fewest parts, reducing failures and
maintenance the most?
Crankshaft position sensor Which component measures engine speed
Both Technician A and Technician B Technician A states that the crankshaft position sensor in distributorless ignition
systems can be mounted at the front, middle, or back of the engine. Technician B
states that the reluctor or trigger wheel can be mounted to the flywheel, the
crankshaft, or the crankshaft pulley. Who is correct?
Cam angle sensors The main advantage of the distributorless ignition system is the elimination of all
mechanical parts included in a distributor assembly such as all of the following
