Abstract
By utilizing high voltage diodes, a special ignition coil, and a special electronic module, a distributorless ignition system (DIS) having solid state high voltage distribution has been designed and constructed. The ignition coil has two opposite polarity high voltage outputs that alternate in phase upon each firing. Each high voltage terminal is connected to two spark plugs through a pair of high voltage diodes that are arranged in back-to-back polarity. The basic DIS package is suitable for igniting a four cylinder engine. DIS has significant advantages in the areas of RFI emissions, packaging, and “rotor registration”.
