PROCESS AND SYSTEM FOR CONTROLLING THE IGNITION SPARK FREQUENCY OF A MULTIPLE SPARK IGNITION SYSTEM

摘要

A process and device optimise combustion in an internal combustion engine, in particular to increase its efficacy, so that the fuel is completely burned and toxic combustion products are avoided. For that purpose, the ignition system has a current source (1), an ignition coil (2), an electronic switch (3) connected to the primary winding of the ignition coil (2), a pulse generator (4) whose output is connected to the electronic switch (3) and at least one spark plug (7). The input of a feedback signal shaper (6) is connected to the output of the ignition coil (2) at the electronic switch (3) and its output is connected to the frequency control input of the pulse generator (4).
