Exam 26: Ignition Systems

Which of the following components is part of the primary ignition circuit?

The distributorless ignition system of a V-6 engine may be designed with three ignition coils.

A ____________________ ignition system has one ignition coil per cylinder and also uses spark plug wires.

Some spark plugs have ____________________-tipped electrodes to extend the life of the plug.

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

Ignition coils are being discussed. Technician A says the primary coil is normally composed of 100 to 200 turns of 20-gauge wire. Technician B says the secondary coil consists of 15,000 to 25,000, or more, turns of very fine copper wire. Who is correct?

What is preignition?

What is the function of the crankshaft position sensor [CKP]?

Reach, heat range, and air gap are all characteristics that affect the performance of which ignition system component?

Resistor plugs are being discussed. Technician A says that if the original equipment resistor plugs are replaced with nonresistor plugs, the engine will produce more power at high RPM. Technician B says that if the original equipment resistor plugs are replaced with nonresistor plugs, the engine will run smoother at low RPM. Who is correct?

Spark plug design is being discussed. Technician A says a plug with too short a reach makes it difficult to attach the plug wire boot. Technician B says a plug with too long a reach may cause preignition. Who is correct?

Describe the term "dwell time."

The misfire monitor uses a high data rate CKP [crankshaft position] sensor to detect engine misfires, and the CMP [camshaft position] sensor is used to identify which cylinder is misfiring.

Which of the following is a component of the secondary ignition circuit?

Which of the following is an advantage of EI ignition?
