About This Quiz

Automobile ignition systems rely on perfect timing.
A simple spark, when delivered at precisely the right moment,
Can mean the difference between a smoothly running,
A powerful engine that operates cleanly and an engine that runs rough,
Lacks power and produces unnecessary emissions. Let’s get your motor running.

1 / 10

For an engine to make the best use of the fuel, the spark should occur before the piston reaches the top of what?

the exhaust stroke

the compression stroke

the intake stroke

2 / 10

The speed of the pistons increases as the engine speed increases. This means that the faster the engine goes, the spark has to occur when?

No change is necessary.

later

earlier

3 / 10

What is it called when the spark timing is moved closer to the top of the compression stroke?

retarding the spark

advancing the spark

promoting the spark

4 / 10

According to the article, retarding the timing may also eliminate what?

compression

knocking

ignition

5 / 10

What is the difference between a “hot” spark plug and a “cold” spark plug?

the lack of a copper gasket

the length of the center electrode

the shape of the ceramic tip

6 / 10

The coil is a simple device — essentially a high-voltage transformer made up of ______ of wire.

a single coil

two coils

three coils

7 / 10

spark plugThe primary role of the distributor is to distribute high voltage from the ______ to the correct cylinder.

spark plug

piston

coil

8 / 10

Spark plugs use this to isolate the high voltage at the electrode, ensuring that the spark happens at the tip of the electrode and not anywhere else on the plug.

a ceramic insert

insulated wires

a copper gasket

9 / 10

Spark timing is so critical to an engine’s performance that most modern cars use a sensor to tell the engine control unit (ECU) what?

the exact temperature of the spark plugs

the exact position of the pistons

the exact location of the coil

10 / 10

In a distributorless ignition system, what component has total control over spark timing?

the spark control unit (SCU)

the engine control unit (ECU)

the coil control unit (CCU)

The average score is 32%
