Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/269976
Kind Code:
A1
Abstract:
A processor of an internal combustion engine control device according to the present invention calculates a target ignition total energy representing a target value of the energy required for ignition of an air-fuel mixture in a cylinder of the internal combustion engine, on the basis of an operating condition of the internal combustion engine and a dilution state of the air-fuel mixture (target ignition total energy calculating unit 41). On the basis of a parameter of the internal combustion engine correlated to the flow rate of the air-fuel mixture in the cylinder of the internal combustion engine at the ignition timing, the processor causes an ignition device to assist a discharge current, and causes the ignition device to generate ignition energy corresponding to the target ignition total energy (target ignition energy realizing unit 43).
