Title:
IGNITION DEVICE OF SPARK-IGNITION INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/196469
Kind Code:
A1
Abstract:
This ignition device of a spark-ignition internal combustion engine, which performs ignition with high energy efficiency while reducing electric power supplied to a sparkplug, uses a control circuit (1) to actuate a DC voltage pulse generating circuit (4) for generating a DC voltage pulse between electrodes of a sparkplug (2), and then actuates an AC pulse generating circuit (3) for generating an AC pulse between the electrodes of the sparkplug (2). Furthermore, the control circuit (1) controls the AC pulse generating circuit (3) with a plurality of group pulses, and allows rest time periods between the group pulses.
