Title:
IGNITION DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/225725
Kind Code:
A1
Abstract:
This ignition control device (1) of an internal combustion engine is equipped with: an ignition coil (2) which has a primary coil (21) and a secondary coil (22); a main ignition circuit unit (3) for performing a main ignition operation; and an energy input circuit unit (4) for performing an energy input operation for superimposing a current of the same polarity on a secondary current (I2). The ignition control device is further provided with a signal generation circuit unit (5) which, on the basis of the waveform information of the main ignition signal (IGT) for controlling the main ignition operation, generates an energy input signal (IGW) for controlling the energy input operation and/or a target secondary current command signal (IGA) which prescribes a target secondary current value (I2tgt).
