Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/235057
Kind Code:
A1
Abstract:
In order to efficiently improve the ignitability of a fuel by a spark plug, this control device for an internal combustion engine comprises a spark control unit 83 that controls the conduction of a spark coil 300 applying electrical energy to the spark plug, said spark plug discharging within a cylinder of the internal combustion engine to ignite the fuel. The spark control unit 83 sets a first electrical energy amount for causing a discharge between electrodes of the spark plug, and a second electrical energy amount for maintaining the discharge, and controls the conduction of the spark coil 300 such that after the supply of electrical energy from the spark coil 300 to the spark plug has been started, when the total amount of supplied electrical energy becomes greater than or equal to the first electrical energy amount, the spark coil 300 is recharged, and then electrical energy greater than or equal to the second electrical energy amount is supplied from the spark coil 300 to the spark plug.
