Starting System Description and Operation 0.8L

Wound field starter motors have pole pieces, arranged around the armature, which are energized by wound field coils.

Enclosed shift lever cranking motors have the shift lever mechanism and the solenoid plunger enclosed in the drive housing, protecting them from exposure to dirt, icy conditions, and splashes.

In the basic circuit, solenoid windings are energized when the switch is closed. The resulting plunger and shift lever movement causes the pinion to engage the engine flywheel ring gear. The solenoid main contacts close. Cranking then takes place.

When the engine starts, pinion overrun protects the armature from excessive speed until the switch is opened, at which time the return spring causes the pinion to disengage. To prevent excessive overrun, the switch should be released immediately after the engine starts.

The engine electrical system includes the battery, the ignition, the starter, the generator, and all the related wiring. Diagnostic tables will aid in troubleshooting system faults. When a fault is traced to a particular component, refer to that component section of the service manual.

The starting system circuit consists of the battery, the starter motor, the ignition switch, and all the related electrical wiring. All of these components are connected electrically.

Distributor distributes the high tension voltage induced from ignition coil, to each spark plug of each cylinder in 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 preliminary current of the ignition coil by the engine control module (ECM).

The ignition timing change is controlled electronically by the ECM.

When diagnosing the ignition system, refer to Electronic Ignition (EI) System Diagnosis .

Ignition coil is a sort of transformer to generate high voltage, 15,000-25,000 volts, 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 (HEI) 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.

It is a part of ignition secondary current, and it burns the compressed mixture by sparking the high voltage induced from the ignition coil.
