ABSTRACT:
An ignition system for generating multiple ignitions during a spark interval of an engine cylinder. For controlling an energy of each one of the multiple ignitions, a ramp signal which linearly rises from an initial peak value of a primary charge current for each one of the multiple ignitions of a primary winding of the ignition coil is compared with a preset value and a charge of the primary winding for each one of the multiple ignitions is stopped when the ramp signal exceeds the preset value. After a predetermined time, a primary charge current is supplied again to the primary winding until the ramp signal exceeds the preset value.
