8-1 ELECTRONIC IGNITION SYSTEM (Solid State Ignition System)

The electronic ignition system features a polver transistor as the current control element. Therefore. the ignition system is an electronic contact point-free type that operates with the po\ver transistor impulses controlling the current. This system also called TIC (transistor igniter circuit) is virtually free of ignition failure which generally results from contamination of the contact points. a typical problem vvrth contact type ignition systems.

Because this ignition system has no contact points. it is not affected by moisture. oil. dust. or other contaminants. 4s a result. this electronic ignition system ensures sure and positive ignition lvith reduced maintenance.

The TIC mechanism consists of a transistor-mcorporated ignition coil and a permanent magneto built-in flywheel which is pressure-fitted on the rotor shaft of the generator.

1)When the permanent magneto built-in flywheel starts rotating. power is generated in the primary coil of the ignition coil and current tlows to the resistor @ _

From the resistor, current flows to the power transistor. RYth this current. the power transistor turns on. releasing current I(@ Thrs stage corresponds to the closmg of contact points.

2)As the tlywheel comes to the point of ignition. the ignition timing detecting circuit is activated while the current @ is flowing through the circuit.

When the ignition timing detecting circuit is activated. the signal transmitter transistor actuates hzith current 8 flow- ing. \Vhen current ,$$ starts flovving. current s flowing through the power transistor is cut quickly. As a result. high voltage is produced in the secondary coil and this voltage is applied simultaneously to the spark plug which ignites for ignition. This stage corresponds to the opening of contact points.
