摘要： The present invention provides an air-fuel ratio feedback control apparatus for an internal-combustion engine. The apparatus includes an air-fuel ratio detector that is disposed in an exhaust system of the engine so as to detect an air-fuel ratio of exhaust gas, NOx purifier for purifying NOx contained in the exhaust gas during a lean operation and feedback controller for making a feedback control upon an air-fuel ratio of air-fuel mixture to be supplied to the engine based on an output of the air-fuel ratio detector. A diagnostic system diagnoses the NOx purifier based on an output of an O2 sensor disposed downstream of the NOx purifier when the air-fuel ratio of the air-fuel mixture to be supplied to the engine has been changed from lean to rich and gain changer for making a feedback control gain of the feedback controller smaller when the air-fuel ratio is changed from lean to rich.

摘要： A control apparatus for a hybrid vehicle of the present invention determines whether a brake switch flag F_BKSW is “1” or not (step S101), and in the case where the brake is on (“yes”), obtains a deceleration regeneration computation value DECRGN by table retrieval from a #REGENBR table. In the case where the brake is off (“no”), it is determined whether a fuel supply cut delay time regeneration flag F_RGNFCD is “1” or not (step S104). In the case where regeneration is not performed in the fuel supply cut delay time (“no”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #REGEN table (step S105). On the other hand, in the case where regeneration is performed in the fuel supply cut delay time (“yes”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #RGNNFCD table (step S106).

摘要： In order to prevent an occurrence of dieseling phenomenon, and to prevent engine rotation speed from decreasing during idle operation or the idle operation from being stopped, in step S111, it is determined whether the flag value of an idle stop flag F_IDLSTP is “1” or not. If it is determined that the determination result is “YES”, that is, if it is determined that the internal combustion engine body is stopped, 0% is set to a target purge control valve drive duty value PGCMD (step S105), and 0 is set to the target purge flow rate QPGC (step S106). If it is determined that the determination result is “NO”, that is, when the internal combustion engine body is in operation, PGCMD calculation processing is executed (step S112). While the internal combustion engine body is stopped, execution of purge is stopped, thereby an occurrence of a dieseling phenomenon which is caused because the flow rate of the air flowing into the internal combustion engine body increases and the air is compressed, is prevented, thereby suppressing vibration from occurring in the internal combustion engine body.
