摘要： PROBLEM TO BE SOLVED: To provide a fuel injection quantity control device for an internal combustion engine which avoids deterioration of driving ability and emission to be generated by a fluctuation of an air-fuel ratio due to injection of the fuel at a quantity increased by adding a quantity to correct adhesion of the fuel. SOLUTION: This fuel injection quantity control device is provided with a fuel operation model for estimating a fuel quantity to be adhered to intake passage structural members, and this model estimates the fuel adhesion quantity, and obtains the fuel adhesion correction quantity. When the intake air quantity (a requested fuel quantity) is small, correction of the fuel injection quantity based on the fuel adhesion correction quantity is limited. Deterioration of driving capability and emission to be generated by a large fluctuation of the air-fuel ratio due to an error contained in the fuel adhesion correction quantity is avoided thereby.

摘要： PROBLEM TO BE SOLVED: To reduce an error included in an estimated fuel adhesion amount or reduce a period in which the fuel adhesion amount is changed, by positively adjusting the fuel adhesion amount. SOLUTION: This system 10 is adopted in the internal combustion engine which comprises: an injector 39 which injects fuel to an inside of an intake passage including an intake pipe 41; and a swirl control valve (SVC) 44 provided inside the intake passage. An electrical control unit 70 estimates the fuel adhesion amount to a member constituting the intake passage based on a fuel adhesion model, and corrects a fuel injection amount of a fuel to be injected from the injector in accordance with the estimated fuel adhesion amount. Further, the SCV is controlled depending on a temporal changing amount of the estimated fuel injection amount, and the fuel adhesion amount is positively adjusted. Accordingly, the temporal changing mount of the fuel adhesion amount is maintained to a small value for example, whereby an adhesion rate used in the fuel adhesion model, and accuracy in a residual rate are improved, thereby reducing the error of the estimated fuel adhesion amount.

摘要： PROBLEM TO BE SOLVED: To provide atmosphere in a catalyst with a stoichiometric air-fuel ratio since a lean operation is switched to a stoichiometric operation. SOLUTION: When an output signal level of NOX ammonia sensor 29 is higher than a first reference level while an air-fuel ratio sensor 30 detects a lean air-fuel ratio in a predetermined period time after switching of the engine operation from the lean operation to the stoichiometric operation, a fuel injection amount is increased and corrected. When the output signal level of NOX ammonia sensor 29 is higher than a second reference level while the air-fuel ratio sensor detects a rich air-fuel ratio in a predetermined period, time the fuel injection amount is decreased and corrected. Thus, a fuel injection amount correcting process is performed.

摘要： PROBLEM TO BE SOLVED: To precisely calculate the total NOx volume absorbed in a NOx catalyst. SOLUTION: This device comprises a NOx catalyst 1 absorbing NOx in exhaust gas when an air-fuel ratio of the inflow exhaust gas is lean and capable of reducing and removing absorbed NOx by a reducing agent in the exhaust gas when the air-fuel ratio of the inflow exhaust gas is rich. An area in the NOx catalyst is divided depending upon the volume of NOx which can be absorbed by the NOx catalyst per unit time at maximum. When the air-fuel ratio of the exhaust gas flowing into the NOx catalyst is lean, the NOx volume absorbed per unit time is calculated in every divided area. After a while, the calculated NOx volumes are summed, so as to calculate the total NOx volume absorbed in the NOx catalyst. COPYRIGHT: (C)2008,JPO&INPIT
