Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2021/095505
Kind Code:
A1
Abstract:
According to the present invention, an ion current during combustion is detected without installing a power storage means on a secondary side of an ignition coil. This control device 1 for an internal combustion engine comprises an ignition control unit that controls electrification of an ignition coil 300 that provides electric energy to an ignition plug 200 that discharges inside a cylinder 150 of an internal combustion engine 100 and ignites fuel. The ignition coil 300 has a primary coil disposed on a primary side and a secondary coil disposed on a secondary side, wherein the first coil has a main primary coil and a sub primary coil. The ignition control unit controls the electrification of the ignition coil 300 so that the sub-primary coil is electrified after the electrification of the main primary coil is cut off.
