Part of Lesson Plan: **Ignition systems types (updated) by Sergio Marquez

Activity Overview / Details

While lecturing, students will follow in their text book (Thomson Delmar Learning, "Automotive Technology: A Systems Approach," 4th edition), pages 595-626.

First, I will explain and show what a standard ignition system consists of, years involved, components and voltage outputs. (For example, early years to about 1974, distributor, cap & rotor, points and condenser, ignition coil, spark plugs and spark plug wires).   Voltage output is about 20KV to 30KV.

Second, I will explain and show  what a high energy electronic ignition system (HEI), consists of, years involved, including the components their function and voltage outputs. (For example, 1975 to 1989, HEI distributor, cap and rotor, ignition module and transistor, pick-up coil, ignition coil, cap and rotor, spark plug wires and spark plugs). Voltage output is about 40KV to 50KV.

Last, I will explain and show what distributorless ignition system consists of, years involved, components and voltage outputs. Explain the coil packs with the waist spark method (for example, 1989 to present date, DIS module, DIS coil pack, crank and cam sensor, spark plug wires and spark plugs). Voltage output 50KV to 60KV. Refer to fig. 24-46.

Explain the benefits, evolution of the DIS, from module, coil-pack, spark plug wires, crank and cam sensor, to no wires, module and individual coils on top of each spark plugs, crank and cam sensor.
