摘要： An estimation device for a cylinder intake air amount in an internal combustion engine is obtained which can estimate an amount of air actually sucked into a cylinder with a high degree of accuracy by using a physical model of an intake system. A volumetric efficiency corresponding value is calculated based on an exhaust efficiency (a linear function of intake pipe internal pressure) which is an index indicating an amount of residual gas which is an exhaust gas after combustion remaining in the cylinder without being discharged from the interior of the cylinder to an exhaust pipe, and an intake efficiency (a linear function of intake pipe internal pressure) which is an index indicating an amount of air coming into the cylinder from an intake pipe excluding the residual gas, whereby the estimation is carried out to a high degree of accuracy with a small number of adaptation constants.

摘要： In throttle control, a throttle opening is set with sufficient control accuracy in accordance with the operating state of an engine despite variations in a throttle body and various kinds of sensors. A target effective opening area is calculated from a target amount of intake air, an atmospheric pressure, an intake pipe internal pressure and an intake air temperature by using a flow rate formula for a throttle type flow meter. A target throttle opening is calculated from a correlation map. An actual effective opening area is calculated from the amount of intake air, the atmospheric pressure, the intake pipe internal pressure, and the intake air temperature by using the above-mentioned flow rate formula, and a learning throttle opening is calculated from the correlation map. The target throttle opening is corrected by a throttle opening learning value calculated from a deviation between the target throttle opening and the learning throttle opening.

摘要： A control apparatus for an internal combustion engine prevents variation of an air fuel ratio even upon introduction of purge air. A delay time occurring until the intake air detected, after having arrived at the combustion chamber through a surge tank, influences an air fuel ratio sensor, a delay time occurring until purge air containing evaporated fuel generated upon purging a canister, after having arrived at the combustion chamber through the surge tank, influences the air fuel ratio sensor, and a delay time occurring until fuel supplied by an injector, after having arrived at the combustion chamber, influences the air fuel ratio sensor, are represented by simplified physical models. A purge rate in the combustion chamber or in the neighborhood of the air fuel ratio sensor is calculated by using the physical models, and a purge air concentration and a fuel correction amount are calculated based on the purge rate thus obtained.
