<p><P>PROBLEM TO BE SOLVED: To protect an electric field generating unit by controlling generation of the electric field correspondingly to the value of the discharge voltage in the capacitive discharge of the spark discharge in a spark ignition type internal combustion engine. <P>SOLUTION: The spark ignition type internal combustion engine has an ignition plug. In the spark ignition method in the spark ignition type internal combustion engine in which plasma is generated and the fuel-air mixture is ignited by reacting the spark discharge generated by the high voltage applied via an ignition coil to be connected to the ignition plug with the electric field generated in a combustion chamber via the ignition plug by an electric field generating unit, generation of the electric field is inhibited when the output voltage of the ignition coil in the capacitive discharge does not reach the predetermined voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
