Abstract: A gasoline engine is provided which is capable of introducing a large amount of EGR gas for performing homogeneous combustion and thus offering a good fuel economy. An external EGR mechanism or an internal EGR mechanism is used to introduce an EGR gas into a combustion chamber (a cylinder). A mixture of fresh air and fuel is thereafter directly injected from a mixture injection valve into the combustion chamber, thereby forming a region of said mixture in an area near an ignition plug. In addition, engine operating parameters are controlled in accordance with the amount of fresh air supplied into the combustion chamber (cylinder) after an intake valve has been closed. This makes possible homogeneous combustion using a large amount of EGR, which eventually increases fuel economy.

To increase the charge temperature in the combustion chamber in the simplest possible manner, there is provided that the residual gases be recirculated through at least one catalyst disposed in the exhaust duct in proximity to the engine.

Abstract: In an estimation apparatus of an air intake flow for an internal combustion engine, an air intake flow rate fed into a portion just upstream of an intake valve at a predetermined timing before starting of fuel injection is calculated based on an output of an air flow meter. A variance in the air intake flow rate caused by the change in the intake pressure at the portion just upstream of the intake vale at the predetermined timing is calculated based on an output of a pressure sensor. The calculated air intake flow rate is added to the variance to obtain an air intake flow rate fed into a cylinder at the predetermined timing. The air intake flow rate fed into the cylinder is corrected to an air intake flow rate required for estimating an actual air intake flow based on an amount of change in the air intake flow rate fed into the cylinder at the predetermined timing.
