This abstract first appeared for US patent application 20250067238 titled 'CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Original Abstract Submitted
a control device for an internal combustion engine capable of performing ignition retardation control in which an ignition timing for igniting an air-fuel mixture in a combustion chamber is retarded from a normal operation. the device includes: an individual cylinder torque calculation unit that obtains a variation amount of combustion torque of each cylinder; an injection amount correction unit that corrects a fuel injection amount for each cylinder so as to reduce the variation amount of combustion torque of each cylinder obtained by the individual cylinder torque calculation unit; and a misfire determination unit that determines a misfire of a predetermined cylinder based on a combustion torque of the predetermined cylinder among the cylinders. when the combustion torque of any one of the cylinders is equal to or less than a predetermined torque, the injection amount correction unit does not correct the fuel injection amount for each cylinder.
