Exam 26: Ignition Systems

A spark plug fires before the piston reaches top dead center (TDC).

The magnetic field surrounding the pickup coil in a magnetic pulse generator moves when the ______.

Conventional ignition systems are capable of producing higher electrical energy than distributorless ignition systems.

The waste-spark ignition system on a four cylinder engine with dual plug [two spark plugs per cylinder] cylinder heads requires four ignition coils.

Electronic ignition systems with a coil for every two spark plugs use the ____________________ spark method of spark distribution.

While discussing electronic ignition systems, Technician A says an NPN transistor in the PCM or ignition module controls primary current flow through the coil. Technician B says coil saturation is controlled by the length of time the primary ignition current is turned on. Who is correct?

Driving on a rough road can trigger the engine misfire monitor.

Describe the term "dwell time."

The hex size (socket size)used for tightening and loosing the spark plugs is either 5/8 in. or ______.

Many of the inputs used for ignition system control are also used to control other systems, such as fuel injection.

A Hall-effect switch generates a ____________________ wave voltage signal.

Explain how the spark plugs fire in a double-ended coil EI system.

Why is reserve voltage necessary in a secondary ignition system?
