INTERNAL COMBUSTION ENGINE CONTROL DEVICE
It is possible to control the EGR amount in a region having a wide range between advance limit ignition timing defined by knock or optimal ignition timing and ignition timing at which combustion instability is detected, making it possible to maximize the EGR amount without deteriorating robustness a...

| description | It is possible to control the EGR amount in a region having a wide range between advance limit ignition timing defined by knock or optimal ignition timing and ignition timing at which combustion instability is detected, making it possible to maximize the EGR amount without deteriorating robustness against disturbance.An internal combustion engine control device that controls the internal combustion engine equipped with an exhaust recirculation passage that allows intake of an exhaust gas of the internal combustion engine again by the internal combustion engine, in which the internal combustion engine includes: a combustion instability calculation unit that calculates a combustion instability of the internal combustion engine on the basis of a rotation speed of the internal combustion engine or an in-cylinder pressure of the internal combustion engine; and a control unit that controls to bring an exhaust recirculation amount together with an ignition advance amount in increasing directions when a difference between an advance limit ignition timing and an ignition timing at which combustion instability has been detected is a predetermined value or more. |
