Ignition System: Description and Operation

GENERAL INFORMATION

OPERATION
- When crankshaft position sensor and camshaft position sensor signal is input to engine control module, engine control module makes ON-OFF control of power transistors one by one.
- When power transistor A is turned from ON to OFF, the spark plugs of No.1 and No.4 cylinders spark. Turning of power transistor B from ON to OFF will produce sparking in spark plugs of No. 2 and No.5 cylinders. Furthermore, when power transistor C is turned from ON to OFF, sparking is produced in spark plugs of No.3 and No.6 cylinders.
- The rest of operation is the same as described for SOHC engine.
