Abstract
A plasma jet ignition system for an internal combustion engine has a plasma jet spark plug which receives ignition energy from two energy sources, one for a spark ignition and the other for a plasma jet ignition, and performs a plasma jet ignition as well as a spark ignition. There are further provided various control circuits to control the ignition energy to reduce energy consumption and to promote the functions of the plasma jet ignition. One of these circuits is arranged to stop the plasma jet ignition during a cranking period while cranking is continued after duration of a plasma jet ignition for a predetermined time period. Another control circuit is arranged to control the plasma jet ignition energy corresponding to the engine temperature.
