GENERAL INFORMATIONM1162000100202
If the ignition switch is turned to the "START" posi-
tion, current flows in the pull-in and holding coils pro-
vided inside magnetic switch, attracting the plunger,
When the plunger is attracted, the lever connected to
the plunger is actuated to engage the starter clutch.
On the other hand, attracting the plunger will turn on
the magnetic switch, allowing the "B" terminal and
"M" terminal to conduct. Thus, current flows to
engage the starter motor.
When the ignition switch is returned to the "ON" posi-
tion after starting the engine, the starter clutch is dis-
engaged from the ring gear.
An overrunning clutch is provided between the pinion
and the armature shaft, to prevent damage to the
starter.

IGNITION SYSTEM
ENGINE ELECTRICAL16-30
IGNITION SYSTEM
GENERAL INFORMATIONM1163000100294
This system is equipped with two ignition coils (A and
B) with built-in power transistors for the No. 1 and
No. 4 cylinders and the No. 2 and No. 3 cylinders
respectively.
Interruption of the primary current flowing in the pri-
mary side of ignition coil A generates a high voltage
in the secondary side of ignition coil A. The high volt
-
age thus generated is applied to the spark plugs of
No. 1 and No. 4 cylinders to generate sparks. At the
time that the sparks are generated at both spark
plugs, if one cylinder is at the compression stroke,
the other cylinder is at the exhaust stroke, so that
ignition of the compressed air/fuel mixture occurs
only for the cylinder which is at the compression
stroke.
In the same way, when the primary current flowing in
ignition coil B is interrupted, the high voltage thus
generated is applied to the spark plugs of No. 2 and
No. 3 cylinders.
The engine-ECU or engine-A/T-ECU
turns the two power transistors inside the ignition
coils alternately on and off. This causes the primary
currents in the ignition coils to be alternately inter
-
rupted and allowed to flow to fire the cylinders in the
order 1-3-4-2.
The engine-ECU or engine-A/T-ECU
determines which ignition coil should be controlled
by means of the signals from the camshaft position
sensor which is incorporated in the camshaft and
from the crank angle sensor which is incorporated in
the crankshaft. It also detects the crankshaft position
in order to provide ignition at the most appropriate
timing in response to the engine operation condi
-
tions. It also detects the crankshaft position in order
to provide ignition at the most appropriate timing in
response to the engine operation conditions.
When the engine is cold or operated at high alti-
tudes, the ignition timing is slightly advanced to pro-
vide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce out
-
put torque, thereby alleviating shifting shocks.
