Title:
SPARK IGNITION CONTROL METHOD FOR SPARK-IGNITED INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/102217
Kind Code:
A1
Abstract:
Provided is a spark ignition control method for a spark-ignited internal combustion engine provided with an ignition plug. In the spark-ignited internal combustion engine, the product, which is generated upon a spark discharge triggered by high voltage applied via an ignition coil connected to the ignition plug, is reacted with an electric field that is generated in a combustion chamber via the ignition plug by an electric field-generating means so as to generate plasma and then ignite a gas mixture. According to this method, the electric field is generated using a positive pulsating current. This configuration can facilitate the spread of combustion after ignition.
