IO. ROBIN SOLID STATE IGNITION ENGINE

10-1 FEATURES

Model EY 15V can employ as option a pointless igniton system, called Solid State Ignition, whichis the cir- cuit breaker type ignition device, utilizing the power transistor as an element for controling electric current.

.This system is outer coil type without pulser and is called T.I.C. (Transistor ignition circuit type). To the EY20V this T,I.C.is equipped as standard parts.

Being different from the breaker point type ignition system, this brand-new system is completely free from such troubles as starting-up failure owing to dirty, burnt or oxidized point surface, lowering of igntion effi- ciency being caused by moisture, rough surface of breaker point and incorrect timing resultant from worn mechanical parts.

10-2 BASIC THEORY of T.I.C. (See Fig. 52.)

1T.I.C.(Transistorigntiontype) consists ofthe fly- wheelandignition coil with built-in transistor;and

its basic theory is as follows: Resister Ignition Coil
