Study Notes

Primary Ignition System Components

Major components include the battery, ignition switch, primary coil winding, ignition module, reluctor and pickup coil, and distributor.

Secondary Ignition System Components

Key components are the secondary coil winding, coil wire, distributor cap and rotor, spark plug wires, and spark plugs.

Battery

Supplies necessary power to the ignition system for engine start-up.

Ignition Switch

Operates the engine by switching power on or off to the ignition system.

Primary Coil Winding

Consists of several hundred turns of heavy wire, functioning as the low-voltage winding within the ignition coil.

Ignition Module

Acts as a transistorized switch that manages the on and off operation of the primary current.

Reluctor and Pickup Coil

Generates a signal for the ignition module; the reluctor is mounted on the distributor shaft, producing a signal in the stationary pickup coil as it rotates.

Distributor

Driven by the camshaft, it is responsible for timing the spark and directing it to the appropriate cylinder, operating at half the speed of the engine.

Secondary Coil Winding

High-voltage winding consisting of several thousand turns of fine wire wrapped around the primary coil winding.

Coil Wire

Transmits high voltage from the secondary coil winding to the distributor cap.

Distributor Cap and Rotor

Directs high voltage from the coil wire to each cylinder in the correct firing order, allowing a single ignition coil to serve all cylinders.

Spark Plug Wires

Carry high voltage from the distributor cap to each spark plug.

Spark Plugs

Generate the spark that initiates combustion, threaded into the cylinder head and extending into the combustion chamber.
