IGNITION COIL AND IGNITION POWER TRANSISTOR <SOHC>
OPERATION
When the power transistor unit A is turned ON by
the signal from the engine control unit, primary
current flows to the ignition coilWhen the
power transistor unit A is turned OFF, the primary
current is shut off and a high voltage is induced
inthe secondarycoilcausingthe ignition
plugsofNo:andNo.cvlindersto spark
When the power transistor unit B is turned OFF,
the ignition plugs of No.2 and No.5 cylinders
spark In addition, when the power transistor unit
is turned OFFthe ignition plugs of No3 and
No. 6 cylinders spark:
Whenthe enginecontrolunit turns OFF the
transistor in the unit, the battery voltage in the
unit is applied to the power transistor unit to turn
it ON. When the engine control unit turns ON the
