Circuit Description
The Electronic Ignition (EI) system uses a waste spark method of spark distribution. The Crankshaft Position (CKP)
sensor sends reference pulses to the ECM. The ECM then triggers the EI system ignition coils. Once the ECM triggers
the EI system ignition coils both of the connected spark plugs fire at the same time. One cylinder is on its compression
stroke at the same time that the other is on the exhaust stroke, resulting in lower energy needed to fire the spark plug in
the cylinder on its exhaust stroke.
This leaves the remainder of the high voltage to be used to fire the spark plug in the cylinder on its compression stroke.
Since the CKP sensor is in a fixed position, timing adjustments are not possible or needed.
