摘要： An ECU calculates the air-fuel ratio of each cylinder based on a sensor signal from an A/F sensor arranged at the collecting portion of the exhaust manifold and feedback controls the fuel injection quantity for each cylinder by using the individual cylinder air-fuel ratio obtained. A collecting portion fuel quantity is calculated from the air-fuel ratio at the exhaust collecting portion based on from the A/F sensor signal, and the gas flow rate at the exhaust collecting portion is calculated using the gas flow rate history of each cylinder. An observer using the individual cylinder fuel quantity as a variable is constructed by a model in which the collecting portion fuel quantity is associated with the individual cylinder fuel quantity, so that the individual cylinder fuel quantity is estimated from the result of observation by the observer. Each cylinder's air-fuel ratio is calculated from the estimated individual cylinder fuel quantity.

摘要： In an apparatus for controlling supply power to a conductive porous carrier of a catalyst converter for cleaning an emission, a moisture determiner determines whether moisture is contained in and/or on the conductive porous carrier. A power controller controls supply power to the conductive porous carrier for energization of the conductive porous carrier such that a value of the supply power to the conductive porous carrier when it is determined that the moisture is contained in and/or on the conductive porous carrier is lower than a value of the supply power to the conductive porous carrier when it is determined that the moisture is not contained in and/or on the conductive porous carrier.

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.

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 upstream catalyst and a downstream catalyst are disposed in series in an exhaust pipe, and first through third sensors for detecting the air-fuel ratio or an adsorption amount of hazardous components on the rich/lean side of exhaust gases are disposed on the upstream and downstream sides of the upstream catalyst and the downstream side of the downstream catalyst, respectively. An ECU for controlling an engine controls the air-fuel ratio so that when the adsorption amount of the hazardous components on the rich side of the downstream catalyst is large, that of the hazardous components on the lean side of the upstream catalyst is large. Similarly, the ECU controls the air-fuel ratio so that when the adsorption amount of the hazardous components on the lean side of the downstream catalyst is large, that of the hazardous components on the rich side of the upstream catalyst is large.

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： In a hybrid vehicle that includes an engine and a motor-generator connected to the engine through a power split device, upon acceleration in a running state, there may arise a case where the rotational speed of the MG1 enters a lockup area and, then, the MG1 cannot pull out of the lockup state with ease in such a manner that the rotational speed of the MG1 is shifted from a normal rotation area to a reverse rotation area, in accordance with an increase of a torque produced by the MG1. In this case, the engine is controlled such that a torque produced by the engine is decreased. Thus, the rotational speeds of the engine and MG1 are reduced entirely, so that the MG1 can pull out of the lockup state without increasing the torque produced by the MG1 any more.
