Abstract
A solid state ignition system for an internal combustion engine is controlled by a spark advance means in relation to one or more parameters affecting spark quality. Supply battery voltage is monitored by the spark advance means whereby the latter generates control signals that regulate primary ignition current so that the latter attains a predetermined level before primary ignition current is interrupted.
