摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of smoothly changing fuel injection control mode arising from the change of an engine load, and suppressing any excessive change of the control mode attributable to any slight load change and the fluctuation of torque accompanied by the change of the control mode. SOLUTION: A fuel injection parameter Q* is determined according to an in-cylinder oxygen amount O2 in a first operational range of an engine, and the fuel injection parameter Q* is determined according to an accelerator pedal step-in amount AP in a second operating range of the engine. When shifted from the first operating range to the second operating range, the fuel injection parameter Q* is determined by using a first shift control map set according to the accelerator pedal step-in amount AP. When shifted from the second operating range to the first operating range, the fuel injection parameter Q* is determined by using a second shift control map set according to the in-cylinder oxygen amount O2.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine smoothly changing a fuel injection control mode along with increase/decrease in engine load, and suppressing torque fluctuation along with excessive switching in control mode caused by a little load change and switching in control mode. SOLUTION: In shifting from a low temperature combustion control for performing low temperature combustion to a normal combustion control performing normal combustion, when an oxygen amount mo2 in a cylinder reaches a first A* map switch threshold value Oxy1, an A* map used for calculating an air adjusting parameter A* for adjusting an intake air amount is switched from a map for the low temperature combustion control to a map for normal combustion control. Then, while keeping engine output torque approximately constant, the oxygen amount mo2 is increased. When the oxygen amount reaches a first Q* map switch threshold valve Oxy3, a Q* map used for calculating a fuel injection parameter Q* performing a control of fuel injection is switched from the map for the low temperature combustion control to the map for normal combustion control.

摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine inhibiting a torque variation on changing of an air-fuel ratio by suitably controlling an injector for injecting fuel into a cylinder. SOLUTION: A cylinder oxygen amount mo2 is estimated according to an engine operation state and a fuel injection parameter Q* is calculated according to the in-cylinder oxygen amount mo2. Fuel injection by the injector is controlled according to the fuel injection parameter Q*. When the air-fuel ratio is changed from a lean air-fuel ratio to a rich air-fuel ratio or when it is changed vice versa, the fuel injection parameter Q* in the transition of the air-fuel ratio is set to smoothly change according to an objective fuel injection parameter Q*tgt and an objective in-cylinder oxygen amount mo2tgt after the change of the air-fuel ratio and to an initial fuel injection parameter Q*ini and an initial in-cylinder oxygen amount mo2ini before the change (S97-S99).
