Electronic ignition for automobile IC engine - uses controller supplying regulating current for end stage transistor in ignition module providing ignition coil current

摘要

The ignition has an ignition module (6) to supply the ignition coil with current of given amplitude, in response to a control current (J1) supplied to the input stage (5) of the ignition module (6), via a control device (1). The amplitude of the control current (J1) is switched between at least 2 values and is used to control an end stage transistor (T3) within the ignition module (6). The end stage transistor pref. acts as part of a current reflector for converting the control current (J1) into a control voltage (U2). ADVANTAGE - Reduction of ignition energy w.r.t. engine operating parameters without additional wiring.
