Chapter 47 Ignition Systems

Ignition coils are basically:

• step-down transformers.

• step-up transformers.

• ballast resistors.

• switching transistors.

A high-voltage spark must cross the spark plug electrode as the piston approaches top dead center (TDC) of the:

• exhaust stroke.

• ignition stroke.

• intake stroke.

• compression stroke.

When the driver turns the key to the start position, an electrical connection is made between the vehicle battery and the ____________ of the ignition coil.

• secondary winding

• ballast resistor

• primary winding

• distributor

The original ignition system found in vehicles was the:

• waste spark system.

• electronic ignition system

• contact breaker points system.

• distributorless ignition system

The type of ignition system in which two cylinders share one coils is called a

• distributor ignition system.

• waste spark ignition system.

• coil-on plug ignition system.

• no answers are correct

Most vehicles today use the _________ type of ignition system.

• coil-on-plug

• waste spark

• breakerless

• distributor

The component the ignition system uses to convert low voltage and high current into high voltage and low current is called the:

• ballast resistor.

• advance mechanism.

• condenser.

• induction coil.

Ignition systems operate according to the laws of induction observed by:

• Pascal.

• Faraday

• Newton.

• Tesla.

The collapse of the magnetic field inside the ignition coil happens as a result of the interruption of current to the:

• primary winding.

• secondary winding.

• ignition control module

• electronic control module (ECM).

The amount of voltage needed to initially get the spark to jump the spark plug gap is called the:

• available voltage.

• required voltage.

• induced voltage.

• no answers are correct.
