摘要： In an emission control system, an absorbent in an exhaust-emission passage absorbs a particular component in the emission with a temperature thereof being lower than a first temperature, and desorbs therefrom the absorbed particular component with the temperature thereof being equal to or higher than the first temperature. A catalyst in the exhaust-emission passage converts the particular component desorbed from the absorbent into another component with a temperature thereof being equal to or higher than a second temperature higher than the first temperature. A heat recovery device is disposed in the exhaust-emission passage upstream of the absorbent and recovers heat from the exhaust emission by heat exchange between a heat-transfer medium and the exhaust emission. An adjusting unit adjusts an amount of heat to be recovered by the heat recovery device to thereby adjust a temperature state of the exhaust emission.

摘要： An apparatus is used for diagnosing the temperature state of a catalyst converter. The catalyst converter includes a catalyst for cleaning an emission, and a conductive carrier for carrying the catalyst. The conductive carrier is energized for temperature rise of the catalyst, and the conductive carrier has a characteristic in which resistance drops with temperature increase. In the apparatus, a first obtaining unit obtains a first parameter having a first correlation with supply power to the conductive carrier for energization of the conductive carrier. A second obtaining unit obtains a second parameter having a second correlation with a temperature of the conductive carrier. A diagnosing unit diagnoses the temperature state of the conductive carrier based on a comparison between the first parameter and the second parameter.

摘要： A catalyst for purifying exhaust gas is provided in an exhaust pipe of an engine. When air-fuel ratio dither control is performed, an ECU calculates a requested torque to be generated by combustion of the engine based on an accelerator opening angle or the like operated by a driver. An MBT estimated torque corresponding to MBT (Minimum advance for the Best Torque) in each case is calculated, and a spark timing retard limit estimated torque corresponding to a spark timing retard limit in each case is calculated. An air-fuel ratio amplitude amount in the air-fuel ratio dither control is calculated based on the calculated requested torque, the MBT estimated torque, and the spark timing retard limit estimated torque. An early activation of a catalyst is realized.

摘要： An exhaust gas cleaning system has two catalysts and three sensors. The target voltage of a second sensor arranged upstream of a downstream catalyst is set according to the output voltage of the second sensor and the output voltage of a third sensor. Thus, even if the output voltage of the second sensor shows a stoichiometric condition and the output voltage of the third sensor shows a rich condition, it is possible to restrict the unnecessary correction of the target voltage and to optimize the cleaning rate of the downstream catalyst. Therefore, it is possible to reduce emission from being impaired by an expected variation in the air-fuel ratio.

摘要： Exhaust gas sensors are provided at the upstream side and the downstream side of a catalyst, respectively. An intermediate target value is set on the basis of the output of the downstream-side exhaust gas sensor of preceding computation time and a final target value that is a final downstream-side target air-fuel ratio. The compensation amount of the upstream-side target air-fuel ratio is calculated on the basis of the deviation between the present output of the downstream-side exhaust gas sensor and the intermediate target value. At least one of an update amount and an update rate of the intermediate value, a control gain, a control period and a control range of a sub-feedback control is varied.
