the sequence of ignition order. It also adjusts the ignition
timing according to the engine condition.
This vehicle uses the distributor (optical sensor type)
which controls the preminary current of the ignition coil
by the ECM.
The ignition timing change is controlled electronically by
the ECM.
When diagnosing the ignition system, refer to Section
1F, Engine Controls.
IGNITION COIL
Ignition coil is a sort of transformer to generate high volt-
age (15,000–25,000V) which can bring spark at the
spark plugs and has an iron cored closed magnetic type.The closed magnetic typed ignition coil is used for the
High Energy Ignition (H.E.I) system. Comparing with the
iron cored open magnetic type, the closed type almost
has no loss of magnetic flux, and smaller in size, so it
produces the high voltage of secondary voltage.
SPARK PLUG
It is a part of ignition secondary current, and it burns the
compressed mixture by sparking the high voltage in-
duced from the ignition coil.
