IGNITION SYSTEM (DIGITAL IGNITOR)

DESCRIPTION

The fully transistorized ignition system consists of the following components: a generator, ignitor, igni-
tion coil and spark plug. The ignition timing is programmed and stored in the ignitor. The pick-up coil
is mounted in the generator. The induced signal in the pick-up coil is sent to the wave-form
arrangement circuit and the CPU receives this signal and calculates the best ignition timing. The CPU
outputs the signal to the transistor of the ignition coil output circuit which is connected to the primary
windings of the ignition coil which is turned "off" and "on" accordingly. Thus, it induces the secondary
current in the ignition coil's secondary winding and produces the spark between the spark plug gap.
